Background Headache is a major neurobiological disorder, affecting one third of the world’s population. It is estimated that up to 10 million people visit the general practitioner for chronic headache in the United States. Headache can be classified as migraine, tension-type, sinus and cluster. Tension-type headache should not be confused with migraine, which is characterised by recurrent attacks of mostly one-sided, severe headache, although some patients suffer from both types of headaches. Tension-type headache is the most common type of primary headache and the disability attributable to it is larger worldwide than that due to migraine. Neuralgia is a stabbing, burning, and often severe pain due to an irritated or damaged nerve. The nerve may be anywhere in the body, and the damage may be caused by several factors including aging, diseases such as diabetes or multiple sclerosis and an infection, such as shingles. It is a sudden, brief and recurrent (refractory condition) pain of the nerve.
Bell’s palsy, also known as acute idiopathic facial paralysis, is an acute peripheral facial neuropathy which is the most common cause of lower motor neuron facial palsy. The incidence of Bell’s palsy is about 11 to 40 per 100,000 adults each year, and Bell’s palsy is known as a non-fatal disease. Most patients recover spontaneously within three weeks.
Motor dysfunction is a frequent and widely recognised complication that often follows stroke. Stroke represents the third leading cause of mortality in Malaysia. Preliminary data found that, on average, 92 stroke admissions occurred each day across all Malaysian healthcare facilities nationwide. Of these admissions, 40.0% of stroke afflicted patients were of younger age-groups (less than 60 years old). Post-stroke survivors were often burdened with disabilities, with estimates of almost seven out of 10 stroke-afflicted survivors being activities of daily living (ADL)-dependent. Guillain Barre is a rare neurological disorder in which the body's immune system mistakenly attacks part of its peripheral nervous system; the network of nerves located outside of the brain and spinal cord. Guillain Barre can range from a very mild case with brief weakness to nearly devastating paralysis, leaving the person unable to breathe independently. Guillain Barre is estimated to affect about one person in 100,000 each year. Transverse myelitis is one of the rarest diseases of the nervous system affecting one or more segments of the spinal cord. Approximately 40.0% of patients with transverse myelitis have pain as their presenting long-term symptom. Despite extensive research efforts on numerous treatment modalities, patient still pursuit for alternative treatment in attempt to further improve the outcome of the disease as mentioned above, such as acupuncture. Acupuncture is defined as the needling of specific points of the body. It is one of the most widely used complementary therapies in many countries. It is claimed that being a relatively simple, inexpensive and safe treatment compared to other conventional interventions, acupuncture has

been well accepted by Chinese patients and is widely used to improve motor, sensation, speech and other neurological functions in patients. As a therapeutic intervention, acupuncture is also increasingly practiced in some Western countries. Hence, this technology review was requested by Neurology Department, Hospital Pulau Pinang, to provide the best available evidence related to acupuncture for the above purpose. Objective/aim To evaluate the efficacy, safety and cost-effectiveness related to acupuncture for neurological disorder; headache, refractory neuralgia, Bell’s palsy, post-stroke, Guillain Barre and transverse myelitis. Results and conclusions A total of 445 titles were identified through the Ovid interface and PubMed. There were 25 articles included in this review which consist of seven systematic reviews and meta-analysis, one systematic review alone, 13 randomised controlled trials (RCT), and two retrospective studies, one prospective observational study and one cost effectiveness and cost analysis study. There was substantial evidence on acupuncture on headache, Bell’s palsy and post-stroke. However, most of the studies have high risk of bias due to inappropriate randomised sequence generation, lack of allocation concealment, inadequate level of blinding, poor description of patient withdrawals from the studies and the adverse events and hence, varying the quality of the included trials. Nevertheless, the evidence showed that acupuncture may reduce headache frequency and improve response rate to treatment. The evidence was inconclusive for Bell’s palsy. As for post-stroke patients, the evidences showed acupuncture may improve ADL. As for other outcomes means, the results were inconclusive. For refractory neuralgia, Guillain Barre and transverse myelitis, there was insufficient evidence to assess the efficacy of acupuncture in these group patients. There were studies reported on adverse events namely, haematoma and ecchymosis, migraine attacks and headache after treatment, pain and fatigue, seizure, and stomach discomfort. Meanwhile, none of the clinical trials reported any serious adverse events. Acupuncture was approved by United States of Food and Drug Administration (USFDA) in 1996 and classified as Class II (special control). In term of cost-effectiveness, acupuncture was suggested to be clinically relevant benefit and cost-effective in certain sectors. In Malaysia, the cost per session varies according to scope of treatment ranges between RM35 to RM315. However, acupuncture service is being provided for RM20 per session at Traditional and Complementary Medicine Unit in Ministry of Health hospitals as per Perintah Fi (Perubatan) (Pindaan) 2017.

Headache is a major neurobiological disorder, affecting one third of the world’s population. It is estimated that up to 10 million people visit the general practitioner for chronic headache in the United States.1 Headache can be classified as migraine, tension-type, sinus and cluster. Tension-type headache should not be confused with migraine, which is characterised by recurrent attacks of mostly one-sided, severe headache, although some patients suffer from both types of headaches. Tension-type headache is the most common type of primary headache and the disability attributable to it is larger worldwide than that due to migraine.2 Neuralgia is a stabbing, burning, and often severe pain due to an irritated or damaged nerve. The nerve may be anywhere in the body, and the damage may be caused by several factors including aging, diseases such as diabetes or multiple sclerosis and an infection, such as shingles. It is a sudden, brief and recurrent (refractory condition) pain of the nerve.3
Bell’s palsy, also known as acute idiopathic facial paralysis, is an acute peripheral facial neuropathy which is the most common cause of lower motor neuron facial palsy. The incidence of Bell’s palsy is about 11 to 40 per 100,000 adults each year,4 and Bell’s palsy is known as a non-fatal disease. Most patients recover spontaneously within three weeks.5
Motor dysfunction is a frequent and widely recognised complication that often follows stroke.6 Stroke represents the third leading cause of mortality in Malaysia.7 Preliminary data found that, on average, 92 stroke admissions occurred each day across all Malaysian healthcare facilities nationwide. Of these admissions, 40.0% of stroke afflicted patients were of younger age- groups (less than 60 years old).

To evaluate the efficacy, safety and cost-effectiveness related to acupuncture for neurological disorder; headache, refractory neuralgia, Bell’s palsy, post-stroke, Guillain Barre and transverse myelitis.
Traditional acupuncture includes the stimulation of precise points on the body through penetration by solid filiform needles developed by the Meridian notions. Stimulating these points is believed to promote the body's natural healing capabilities and enhance its function. It can be associated with the application of heat, pressure, or laser light to these same points. There are two very different ways of looking at acupuncture; from the traditional Chinese medicine and modern international perspective.15 Figure 1 shows several types of acupuncture. (a) (b) (c) Figure 1: 1(a) normal acupuncture, 1(b) electro-acupuncture, 1(c) moxibustion acupuncture. In traditional Chinese medicine, acupuncture is linked to the belief that disease is caused by disruptions to the flow of energy in the body (called qi, pronounced "chee"). In the Western view, acupuncture likely works by stimulating the central nervous system (the brain and spinal cord) to release chemicals called neurotransmitters and hormones. These chemicals dull pain, boost the immune system and regulate various body functions.16

5.2 Critical appraisal of the included studies
The risk of bias assessment for RCT was assessed using Cochrane Risk of Bias Assessment tool (ROB 2.0) reference. For other study designs, a few important domains were selected to assess the risk of bias. This is achieved by answering a pre-specified question of those criteria assessed and assigning a judgement relating to the risk of bias as either:
+ Indicates YES (low risk of bias)
? indicates UNKNOWN risk of bias
- Indicates NO (high risk of bias)
Risk of bias assessment of the included studies are summarised according to their study design as below.

5.3 Efficacy/ Effectiveness 5.3.1. Headache Ten studies reported the efficacy of acupuncture, of which one was a systematic review with meta-analysis and nine RCTs. 5.3.1.1. Headache frequency A systematic review with meta-analysis by Sun Y et al. (2008) evaluated the efficacy of acupuncture for treatment of chronic headache. Following databases were searched: CENTRAL, MEDLINE, CINAHLS and Scopus up to November 2007 and database of a Chinese medical journal. Thirty-one of 102 potentially relevant studies involving 3916 participants met the inclusion criteria. Seventeen studies included patients with migraine, 10 included patients with tension-type headache and four included patients with mixed chronic headache. The quality of the more recent trials was higher than the previous trials, with more emphasis on proper randomisation, allocation concealment and description of patient dropout. For acupuncture versus medication treatment, two trials reported the SMD in headache frequency was in favour of the acupuncture group. Days with headache per month and attacks (frequency) per months was -0.22 (95% CI: -0.41, -0.03) and -1.22 (95% CI: -2.34, -0.10) respectively.17, level I Wang K et. al (2007) conducted an RCT to examine the effect of acupuncture-like electrical stimulation on chronic tension-type headache in a randomised, double-blinded, placebo-controlled study. Thirty-six adult patients (more than 18 years old) diagnosed with chronic tension-type headache were divided randomly into the treatment and placebo (control) group with 18 in each. The number of headache attacks in the two weeks (Treat-1) during the treatment period was slightly decreased from 10.5 ± 4.6 to 9.5 ± 5.9 and to 8.4 ± 5.7 in the treatment group. There were also slight decreased of headache attack frequency from 11.5 ± 4.0 to 10.6 ± 3.8 at Treat-1 and to 10.7 ± 3.8 in the placebo group. However, there was no significant difference between the two groups (p=0.169) (see Figure 4). After treatment, two out of 36 patients reported that their headache pain had been totally relieved, four patients felt much better, seven patients felt slightly better, 22 patients felt no change, and one patients felt slightly worse.18, level I

Another RCT by Gottschling S et al. (2008) was conducted to investigate whether active laser acupuncture reduced headache frequency more effectively than placebo laser acupuncture in children with migraine or tension-type headache. The 48 patients diagnosed with unilateral or bilateral headache or migraine or tension-type headache (children with age less and equal than 17 years old) were randomly divided into active laser acupuncture group and placebo laser acupuncture group, with 24 patients in each. The study was carried out between October 2006 and March 2007 at two medical centres. The results showed that there was a significant decrease in headache frequency compared to baseline in the active laser treatment group. The mean improvement in headache frequency was significantly greater in the treatment group than the placebo group. From baseline to week five to eight, the number of days decreased by 7.0 days in the active acupuncture group compared to 1.2 days in the placebo group. The difference between active acupuncture versus placebo acupuncture was 5.4 days (p<0.001). The decrease in headache frequency in the placebo group was not significant compared to baseline (p=0.145). Whereas, the headache frequency in the placebo group reached baseline level in weeks nine to 12, headache frequency in the active acupuncture group stayed low until the study endpoint (p<0.001) (see Figure 5).19, level I Figure 5: Headache frequency. Arrow indicating time phase when weekly acupuncture sessions took place. White stars indicating significant changes compared to baseline. Black stars indicating significant differences between placebo and active acupuncture with * indicating (p<0.05) and ** indicating (p<0.001). Data are presented as means. Error bars indicate standard error of the mean (SODM).19, level I
An RCT by Alecrim-Andrade J et al. (2008) was conducted to assess the efficacy of acupuncture in migraine prophylaxis. Thirty-seven patients who were diagnosed with migraine (with or without aura) were divided randomly into the real acupuncture and sham acupuncture groups with 19 and 17 in each. The study was conducted between December 2001 and June 2003 with six months of follow up. The differences with statistical significance between groups appeared in the second month of the treatment. Greater improvement was observed in the real acupuncture group. From the third month of the treatment to the late post-treatment follow-up, the statistical difference between groups disappeared (see Figure 6).20, level I

In this figure, the p value referred to the differences between groups.20, level I
Gildir S et al. (2019) conducted an RCT to explore the effectiveness of trigger point dry needling in patients with chronic tension-type headache. One hundred and sixty-one adult patients (age 20 to 50 years old) who were diagnosed with chronic tension-type headache were divided randomly into a dry needling and sham dry needling groups, with 80 and 81 in each. The trial was carried out between April and August 2017 with one month of follow up. The Friedman test revealed a statistically significant differences between measurements in both groups (all p values were less than 0.05). In the dry needling and sham dry needling group, pairwise comparisons revealed that there were statistically significant differences for headache frequency (p<0.05) (see Table 1).21, level I Table 1: Comparisons of headache intensity, frequency and headache duration at prior to treatment, at the end of therapy and at a one-month follow up, x±s, (95% CI).21,

Another RCT by Tavola T et al. (1992) was conducted to evaluate the efficacy of acupuncture in the treatment of headache pain. Thirty patients who were diagnosed with tension-type headache were allocated randomly into Chinese traditional acupuncture and sham acupuncture group, with 15 in each. The patients were followed up for 12 months. The results reported that the frequency of episodes decreased significantly over time (from baseline period [t0] to t3) (F<time>=16, 34;
MaHTAS Technology Review
12
df=3, 84; p<0.001). The mean decrease of episode frequency from the t0 to t3 was 44.3% and 21.4% in acupuncture and placebo-treated patients, respectively.22, level I
5.3.1.2. Duration with headache Vickers AJ et al. (2004) conducted an RCT to determine the effects of a policy of using acupuncture, compared with a policy of avoiding acupuncture, on headache in primary care patients with chronic headache disorders. Four-hundreds and one adult patients (age 18 to 65 years old) who were diagnosed with migraine or tension-type headache were randomly assigned to acupuncture and no acupuncture groups, with 205 and 196 in each. The recruitment took place between November 1999 and January 2001 with one year of follow up. The result showed that differences between groups were not sensitive to the definition of headache day.23, level I Another RCT by Linde K et al. (2005) was conducted to investigate the effectiveness of acupuncture compared with sham acupuncture and with no acupuncture in patients with migraine. Three-hundreds and two patients (adults of age 18 to 65 years old) who were diagnosed with migraine (with or without aura) were divided randomly into acupuncture, sham acupuncture and waiting list control groups, with 145, 81 and 76 in each. According to Figure 7, between baseline and week nine to 12 the number of days with headache of moderate or severe intensity decreased by a mean (standard deviation [SD] of 2.2 (2.7) days in the acupuncture group versus 2.2 (2.7) days in the sham acupuncture group and 0.8 (2.2) days in the waiting list group (difference acupuncture versus sham acupuncture, 0.0 days; 95% CI: -0.7, 0.7; p=0.96; acupuncture versus waiting list, 1.4 days, 95% CI: 0.8, 2.1; p=0.001). Response differences in the waiting list group became apparent after the first four weeks of treatment and increased until week 12. Furthermore, results in the sham acupuncture group tended to be slightly better than those in the acupuncture group, however the differences were not significant.24, level I

Melchart D et al. (2005) conducted an RCT to investigate the effectiveness of acupuncture compared with minimal acupuncture and with no acupuncture in patients with tension-type headache. A total of 270 adult patients (age 18 to 65 years old) who were diagnosed with episodic or chronic tension-type headache were assigned to acupuncture, minimal acupuncture and no acupuncture (waiting list) groups randomly, with 132, 63 and 75 in each group. The follow up took place for six

months. From baseline to week nine to 12, the number of days with headache decreased by 7.2 (SD 6.5) days in the acupuncture group compared with 6.6 (SD 6.0) days in the minimal acupuncture group and 1.5 (SD 3.7) days in the waiting list group (difference: acupuncture versus minimal acupuncture, 0.6 days, 95% CI: 1.5, 2.6; p=0.58; acupuncture versus waiting list, 5.7 days, 95% CI: 4.2, 7.2; p<0.001).25, level

There was a significant decrease in monthly headache hours in the active acupuncture group compared to baseline with the mean improvement being greater in the active acupuncture group. The mild benefit of placebo acupuncture disappeared after eight weeks from baseline whereas the beneficial effect of active laser acupuncture lasted until the end of the follow up. The monthly headache hours decreased almost solely due to a reduction of the headache frequency.19, level I It was reported that greater improvement was observed in the real acupuncture group. From the third month of the treatment to the late post-treatment follow-up, the statistical difference between groups disappeared (see Figure 8).20, level I

Diary 1 = baseline period, diary 2 = first month of the treatment, diary 3 = second month of the treatment, diary 4 = third month of the treatment, diary 5 = first month after the treatment, and diary 6 = sixth month after the treatment. In this figure, the p value is referred to the differences between groups.20, level I
5.3.1.3. Headache intensity and headache score For acupuncture versus sham acupuncture groups, the pooled data showed there was no significant difference between acupuncture and sham groups at either early follow-up period. Combined data from three trials in migraine headache also did not show any difference. However, combined data from seven trials at the late follow-up period showed a weight mean difference (WMD) of -2.62 mm in favour of acupuncture (95% CI: -5.07, -0.17). For acupuncture versus medication treatment groups, the patients receiving acupuncture from two trials reported significant improvement at the early follow-up period (WMD: -8.54 mm, 95% CI: -15.52, -1.57) but the result was heterogeneous (see Figure 9).17, level I Furthermore, the average headache intensity was lower at Treat-1 (two weeks) and Treat-2 (up to four weeks) compared with the baseline. The pain intensity decreased from 4.9 ± 1.1 to 3.9 ± 1.6 at Treat-1, and to 3.3 ± 1.8 at Treat-2 in the treatment group. The effect size was 0.73 (95% CI: 1.93, 0.08) and 1.03 (95% CI: 2.58, 0.53).18, level I

Gottschling S et al. (2008) reported that the pain intensity in the active treatment group decreased significantly compared to baseline. The improvement in the active acupuncture group was greater than in the placebo group. Nevertheless, there was a significant beneficial effect of placebo laser acupuncture in weeks one to four and 13 to 16 from baseline (p=0.024; p=0.004). The effect of the active laser acupuncture on pain severity was weaker than the other parameters but still significantly superior compared to placebo acupuncture at all times points (p<0.001).19, level I Meanwhile, for dry needling and sham dry needling groups, pairwise comparisons revealed that there were statistically significant differences for headache intensity (p<0.05).21, level I
Severity of headache was recorded by using a daily diary four times a day on a six-point Likert scale (0 = no headache, 5 = intense, incapacitating headache) and the total summed to give a headache score. In the primary analysis mean headache scores were significantly lower in the acupuncture group. Scores fell by 34.0% in the acupuncture group compared with 16.0% in controls (p=0.0002). When the pre-specified cut-off of 35.0% was used as a clinically significant reduction in headache score, 22.0% more acupuncture patients improved than controls, equivalent to a number needed to treat of 4.6 (95% CI: 9.1, 3.0). The effects of acupuncture seemed to be long lasting; although few patients continued to receive acupuncture after the initial three-months treatment period (25, 10, and six patients received treatment after three, six and nine months respectively), headache scores were lower at 12 months than at the follow-up after treatment.23 level I 5.3.1.4. Response rate Response rate was an overall assessment of improvement after treatment. Response was defined as at least 33.0% improvement by assessing headache index or by overall evaluation. For acupuncture versus sham acupuncture, 14 trials reported data on the proportions of patients responding to treatment at an early follow-up period. Combined data demonstrated a statistically significant higher response rate in the acupuncture group compared with sham acupuncture. Five-hundred ten of 961 (53.0%) acupuncture patients. A significant difference was also found in subgroup analysis for tension-type headache. Risk ratio was 1.26 (95% CI: 1.10, 1.44) without heterogeneity (I2=0). However, there was no significant difference between treatment groups for migraine. Only two studies reported the response rate at late follow-up in

which combined data show that RR was 1.22 (95% CI: 1.04, 1.43), again without heterogeneity (I2=0) (see Figure 10).17, level I Figure 10: Response rate in acupuncture versus sham-controlled trials for chronic headache. RR relative risk; CI confidence interval.17, level I
For acupuncture versus medication treatments groups, the pooled data from seven trials showed 62.0% of patients receiving acupuncture had a significantly higher response rate to treatment, compared with 45.0% of patients receiving medication at the early follow-up period. Risk ratio was 1.80 (95% CI: 1.16, 2.81). This significant difference was also found at one-year follow-up in one study.17, level I
5.3.1.5. Quality of life (QoL) Various scales and questionnaires were provided to assess health-related quality of life (QoL). The combined data of four studies by Sun Y et al. (2008) showed no significant difference between acupuncture and sham acupuncture in both physical and mental health, in either the early follow up or late follow up period. For acupuncture versus medication treatments groups, three trial reported suitable data for health-related QoL in the early-period. Pooled data from three trials showed that acupuncture produced significantly better physical function in the early follow-up period (WMD: 4.16, 95% CI: 1.33, 6.98). However, no significant difference was found in mental health. One study reported that patient well-being improved in the physiotherapy treatment group only when compared to acupuncture.17, level I
The short-form (SF-36) health status questionnaire was completed at baseline, three months and one year. Every three months after randomisation, patients completed additional questionnaires that monitored use of headache treatments and days sick from work or other usual activity. The results reported that SF-36 data generally favoured acupuncture, although differences reached statistical significance only for physical role functioning, energy and change in health.23, level I Table 2 shows

statistically significant differences between the groups on the following subscales. The Mann-Whitney U test revealed statistically significant differences between the groups on the subscales of physical functioning, role physical, bodily pain and vitality. General Linear Model revealed statistically significant differences between the groups on the general health, social functioning, role emotional and mental health subscales after controlling for the differences of the initial measurements.21, level I

5.3.1.6. Medication score/ days with medication Medication use was assessed by asking patients to describe the exact proprietary name of the drugs that they were taking and the number of doses of each. Medication scores at follow-up were lower in the acupuncture group. Although differences between groups did not reach statistical significance for all end-points. Total medication taken by patients after randomisation, weekly use fell by 23.0% in controls, but by 37.0% in the acupuncture group (adjusted difference between groups 15.0%, 95% CI: 3, 27, p=0.01).23, level I Other three studies reported that there was a reduction in the total intake of rescue medications in control and intervention groups. However, there were no statistical significant differences between them.18,20,22, level l
5.3.1.7. Use of alternative treatments and Minor Symptom Evaluation Profile
(MSEP) Sodenberg EI et al. (2011) conducted an RCT to study the comparison of three non-pharmacologic treatments; acupuncture, relaxation training and physical training on subjective well-being patients with chronic tension-type headache. Eighty-eight of adult patients (age 18 to 65 years old) who were diagnosed with chronic tension-type headache were randomly assigned to acupuncture, physical training and relaxation training groups, with 29, 30, and 29 in each. The patients were followed up for six months. The Minor Symptom Evaluation Profile questionnaire (MSEP) was used to assess central nervous system (CNS)-related symptoms. The MSEP comprised of 24 self-administered standardised items using a visual analogue scale (VAS); low scale values reflect positive feeling, high scale values reflect negative feeling. The items were categorised into three dimensions; contentment (happiness, self-control, well-being), vitality (enthusiasm, endurance, responsiveness) and sleep (nocturnal, quality, insomnia).26, level I For between-group comparisons, no difference in MSEP was found immediately after treatment among the three treatment groups, when total scores were compared. At the three-months follow-up, the proportion of individuals with an improved total score
MaHTAS Technology Review
17
was significantly greater in the physical training group compared with the acupuncture group (p=0.036). At the six-months follow-up, the proportion of individuals with improved levels was maintained in the physical training group and slightly increased in the relaxation training group. No significant differences were found at the six-month follow-up. Vitality was significantly higher in the relaxation training group compared with the acupuncture group at the six-months follow-up (see Table 3). Sleep was also significantly higher in the relaxation training group compared with the acupuncture group at the six-months follow-up. When the contentment dimensions were compared, no significant difference was found.26, level I Table 3: Proportions of individuals with an improved vitality dimension score of at least 10 or at least 25 VAS units, by treatment group.26, level I
Meanwhile for within-group comparisons, in the acupuncture group (n=30), total MSEP scores of 17 (56.7%) patients were improved immediately three and six months after treatment compared with baseline. In the physical training group (n=30), total scores were improved in 19 patients (63.3%) immediately after training and in 26 (86.7%) and 24 (80.0%) patients at the three-month and six-month follow-ups, respectively, compared with baseline. In the relaxation training group (n=30), total scores were improved in 23 (76.7%) patients immediately after treatment and in 20 (66.7%) and 22 (73.0%) patients at the three-month and six-month follow-ups, respectively, when compared with baseline.26, level I 5.3.2. Refractory neuralgia There was no comparative study retrieved to show the efficacy of acupuncture on refractory neuralgia. 5.3.3. Bell’s palsy Three studies reported the efficacy of acupuncture, of which, two were systematic reviews with meta-analysis and one RCT. Zhang R et al. (2019) conducted a systematic review with meta-analysis to investigate whether Bell’s palsy patients would benefit from acupuncture treatment comparing with drug therapy. The search was done without language restrictions via: PUBMED, EMBASE, CENTRAL, CNKI, Wan Fang Database up to July 2018. Eligible studies included RCT with intervention of manual acupuncture therapy (combined or not

combined with moxibustion) and compared with drug therapy. Two investigators independently extracted the information from each study. A 323 potentially relevant studies were found, of which 11 publications (1256 patients who were diagnosed with Bell’s palsy; facial paralysis or idiopathic facial paralysis or herpetic facial paralysis) fit the criteria for inclusion. Of those 11 publications, three trials used acupuncture combined with moxibustion, and the rest eight trials used traditional acupuncture. The results however, should be interpreted cautiously, because of the poor quality of included studies due to the insufficient information. Analysis of the risk of bias indicated that the high-risk bias of the included studies was mainly due to the fact that the study process was not blinded or unreported, and assessment of the results were not blinded or unreported. The outcomes were measured on the cure rate and total effective rate. The total cure rates for the acupuncture and drug groups were 59.7% and 32.5%, respectively. Acupuncture treatment was associated with an increased cure rate (RR=1.77, 95% CI: 1.41, 2.21), with significant heterogeneity in the pooled results (I2=67%, p=.0008) (see Figure 11). The total effective rates in the acupuncture and drug groups were 96.9% and 83.0%, respectively. Acupuncture therapy was associated with an increased total effective rate (RR=1.18, 95% CI: 1.07, 1.31, with significant heterogeneity in the pooled results (I2=90%, p<.00001). The authors concluded that acupuncture seemed to be an effective therapy for Bell’s palsy.27, level I
Figure 11: Meta-analysis on acupuncture for cured rate on Bell’s palsy.27, level I
Another systematic review with meta-analysis was conducted by Li P et al. (2015) to assess the efficacy of acupuncture for Bell’s palsy. Two investigators independently extracted the information from studies which were retrieved via: PUBMED, EMBASE, CENTRAL up to July 2014. Eligible studies included RCTs that limited the intervention acupuncture technique to conventional stimulation of points by needle insertion and electric acupuncture stimulation. A 249 potentially relevant studies were found, of which 14 publications fit the criteria for inclusion. Of those 14 publications, five studies used electro-acupuncture technique and nine studies used conventional acupuncture. Almost all studies included were of poor methodological quality and all the selected studies were considered at high risk of bias or unclear bias. The total effective response rates in 13 trials were reported in the acupuncture and control groups, were 95.48% and 82.81%, respectively. Acupuncture therapy was associated with an increased total effective response rate (RR 1.14, 95% CI: 1.04, 1.25, p=0.005), with significant heterogeneity among the included studies (I2=87%). In the subgroup analysis, eight articles compared acupuncture plus drug therapy against drug therapy in patients with Bell’s palsy and eleven studies compared acupuncture

19
against other interventions. The total effective response rates of these two groups were 96.47% and 96.33%, respectively. Significant associations were observed in both groups (acupuncture plus drug group: RR 1.14, 95% CI: 1.08, 1.20, p<0.00001; acupuncture group: RR 1.11, 95% CI: 1.00, 1.24, p=0.05). No heterogeneity was found in the acupuncture plus drug subgroup (I2=19%, p=0.29). However, there seemed to be huge degree of heterogeneity in the acupuncture versus other intervention subgroup (I2=90%, p<0.00001) and that versus drug therapy subgroup (I2=84%, p<0.00001). A total of six studies compared acupuncture against drug therapy, and the result showed significant association in these two groups (RR 1.18, 95% CI: 1.02, 1.36, p=0.02). There were three studies comparing acupuncture against blank control. However, the meta-analysis of these three studies was not performed due to unavailability of data. The authors concluded that, the current available evidence was insufficient to support that acupuncture was an effective therapy for Bell’s palsy due to the poor quality of included researches.28,
level I Zhang CY et al. (2016) conducted an RCT to evaluate the effects of the traits of personality on the objective outcome when different acupuncture techniques were used in treating patients with Bell’s palsy. The 316 adult patients (age 18 to 65 years old) who were diagnosed with facial nerve weakness were allocated randomly into acupuncture (with de qi) and acupuncture (without de qi) control groups. The outcome was measured on the House-Brackmann score: a score to grade the degree of nerve damage in a facial nerve palsy (grade I - normal, grade II - slight dysfunction, grade III - moderate dysfunction, grade IV - moderate severe dysfunction, grade V – total dysfunction, grade VI - total paralysis), and 16 Personality Factors (16PF): an assessment tool used to establish a person’s personality, usually in the form of a test consisting of a questionnaire. After six months, it was found that more patients had complete recovery in de qi group (89.8%) than control group (70.8%) (adjusted for age, gender, treatment center, interval between onset of palsy and start of treatment, House-Brackmann score on day one; adjusted odds ratio [OR]: 4.16, 95% CI: 2.23, 7.78). For the comparison between the groups, see Table 4. It was found that in both groups, the score of experience and belief in acupuncture questionnaire, gender, age, education status, occupation, and attention had no prominent effects on objective outcome after six months. The authors concluded that the needle sensation of fullness could predict better facial function and personality traits might influence outcomes of acupuncture treatment.29, level I Table 4: Analyses of factors associated with complete recovery for Bell’s palsy.29, level

5.3.4. Post-stroke Nine studies reported the efficacy of acupuncture, of which five were systematic reviews with meta-analysis, one systematic review without meta-analysis and three RCTs. 5.3.4.1. Motor function Zhan J et al. (2018) conducted a systematic review with meta-analysis to assess the effectiveness and safety of electro-acupuncture combined with rehabilitation therapy and/or conventional drugs for improving post-stroke motor dysfunction. They searched the following English electronic databases: China National Knowledge Infrastructure, Chinese Biological Medicine Database, Chinese Scientific Journal Database (VIP), Cochrane Library, MEDLINE, EMBASE, PUBMED and Cochrane up to December 2016. Eligible studies included RCTs that evaluated clinical efficacy of electro-acupuncture in adult patients (age more than 18 years old) with non- electro-acupuncture. The review included 19 RCTs involving 1434 patients; all trials were conducted in China only. Of those 19 publications, 16 trials compared electro-acupuncture plus conventional drugs and rehabilitation therapy with conventional drugs plus rehabilitation therapy. Three trials gave electro-acupuncture and rehabilitation therapy to the experimental groups, while the control groups only received rehabilitation therapy. Most of the included trials had methodological defects. The funnel plots of Fugl-Meyer Assessment Scale (FMA) and Egger’s tests suggested a potential publication bias. These issues potentially lead to high risk of bias.30, level I The outcome of interest was measured in 13 trials with 1010 patients. There were no significant differences in treatment duration in the meta-regression model (adjusted R2: 0.124, t=−1.57, p=0.144). The FMA score in the electro-acupuncture group increased more than those in the non-electro-acupuncture group, and there was a significant difference (WMD 10.79, 95% CI: 6.39, 15.20, p<0.001). For FMA of upper extremity (FMA-U), one trial with 98 participants used the FMA for upper extremity to evaluate the function of the upper extremity, and the difference between the electro-acupuncture group and the non-electro-acupuncture group was significant (p<0.050). Furthermore, the FMA for lower extremity (FMA-L) was also assessed in four trials with 234 participants. There was a significant difference between the electro-acupuncture group and the non-electro-acupuncture group in the FMA-L (WMD 5.16, 95% CI: 3.78, 6.54, p<0.001). In the subgroup analysis (electro-acupuncture plus rehabilitation therapy and conventional drugs versus rehabilitation therapy plus conventional drugs), 10 trials used FMA to measure the motor function of 796 participants with post-stroke motor dysfunction. A random-effects model was used to analyse the effect on FMA due to significant heterogeneity. There was a significant difference between electro-acupuncture combined with rehabilitation therapy and conventional drugs versus rehabilitation therapy plus conventional drugs (WMD 8.03, 95% CI: 5.17, 10.90, p<0.001). Three trials with 214 participants applied FMA to compare the effectiveness of electro-acupuncture plus rehabilitation therapy against rehabilitation therapy alone. Meta-analyses with a random-effects model were performed on three trials to evaluate the effect on FMA in this subgroup analysis owing to statistical heterogeneity. There was a significant difference in these three trials favouring electro-acupuncture plus rehabilitation therapy plus conventional drugs against rehabilitation therapy plus conventional drugs only (WMD 20.90, 95% CI: 18.61, 23.19, p<0.001).30, level I

Another systematic review with meta-analysis by Yang A et al. (2016) was conducted to determine the efficacy and safety of acupuncture therapy in people with subacute and chronic stroke. The search included 10 computerised literatures such as Cochrane Stroke Group Trials Register, CENTRAL, MEDLINE, EMBASE, CINAHL, AMED, China Biological Medicine Database, Chinese Science and Technique Journals Database, China National Infrastructure and Wan Fang database up to July 2015. All RCTs that compared acupuncture with needling, with placebo acupuncture, sham acupuncture and no acupuncture in the treatment of patients in the subacute or chronic stage were included. The methodological quality of most of the included trials was not high. The quality of evidence for the main outcomes was low or very low based on the assessment using GRADE. Many studies did not provide detailed information on the severity of the disease, the exact time of starting the acupuncture treatment, the modalities of acupuncture technique and acupuncturist's background, and possible adverse effects relevant to acupuncture treatment. The result found that there was no evidence of effectiveness in terms of changes in motor function between real acupuncture and sham acupuncture among people with stroke in the convalescent stage.31, level I Sze FKH et al. (2002) conducted an RCT to examine whether acupuncture has additional value to standard post-stroke motor rehabilitation. One hundred and six Chinese patients who were diagnosed with haemorrhagic or ischaemic stroke were divided randomly into Traditional Chinese manual acupuncture and no acupuncture groups, with 31 (the patients were divided into group 1A; received five weeks [± 1 week] of inpatient rehabilitation, followed by five weeks [± 1 week] of day hospital rehabilitation, and group 1B; received three weeks [± 1 week] of inpatient rehabilitation, followed by seven weeks [± 1 week] of day hospital rehabilitation) and 22 (the patients also divided into group 2A and 2B, who received the same routine as group 1A and 1B) in each. No differences were seen between the intervention arm and the control arm in either group 1 or group 2, when comparing impairment scores of FMA of Physical Performance - Motor subsection (FMAM) and FMA at 10 weeks.32,
level I Another RCT was conducted by Johansson BB et al. (2001) to study effects of acupuncture and transcutaneous electrical nerve stimulation on functional outcome and quality of life after stroke versus a control group that received subliminal electrostimulation. One hundred and fifty patients with acute stroke were allocated into acupuncture, transcutaneous electrical nerve stimulation and subliminal electrostimulation control groups randomly, with 48, 51 and 51 in each. Overall motor function showed that in intention-to-treat analyses, no clinically meaningful or statistically significant differences existed. Moreover, most patients in all groups were unable to score more than zero in the Nine Hole Peg Test, which was used to assess fine motor function of the affected hand.33, level I Junhua Z et al. (2009) conducted a systematic review to determine whether complex Traditional Chinese Medicine (cTCM) treatments improves post-stroke motor recovery. Two independent reviewers searched the following electronic databases through December 2007: PubMed, EMBASE, CBM, the Cochrane Library, and other Chinese journal databases. All RCTs that compared cTCM with acupuncture (with or without physical exercise) were included. A total of 11235 potentially relevant studies

were found, of which 34 publications (4521 patients with ischaemic or haemorrhagic stroke) fit the criteria for inclusion. All the included studies were single-centre, parallel-design and randomised. In general, the methodological quality of the trials included was poor. According to the Cochrane handbook, all of the trials included were of low quality classified as “C”. A strong publication bias was present in the review as the asymmetry of the funnel plot was reported. The results showed that four of the 12 trials of cTCM versus acupuncture alone showed statistically significant higher effective rate ratio (ERR) after treatment with the cTCM ([ERR=1.37: 95% CI: 1.02, 1.85], [ERR=1.38; 95% CI: 1.06, 1.80], [ERR=1.57; 95% CI: 1.18, 2.08], [ERR=1.11: 95% CI: 1.03, 1.20]). The remaining eight trials did not show statistically significant differences between the experimental and control groups. In two other trials the control group included acupuncture plus physical exercise, only one showed a statistically significant result (ERR=1.16; 95% CI: 1.04, 1.31).36, level I 5.3.4.2. Activities of daily living (ADL) Kong JC et al. (2010) conducted a systematic review with meta-analysis to critically evaluate the effectiveness of acupuncture as an adjunct to mainstream stroke rehabilitation. The study searched 20 computerised literatures which were MEDLINE, AMED, CINAHL, EMBASE, PsycINFO, British Nursing Index, Cochrane Library, Asian journals and 12 major Korean traditional medicine journals up to October 2009. The RCTs that compared acupuncture and electro-acupuncture with sham acupuncture and sham electro-acupuncture in the treatments of patients with acute, subacute and chronic stage of stroke were included. Applicable follow up were six months. The PEDro score was used to determine the quality of clinical trials and consists of a checklist of 10 scored yes-or-no questions pertaining to the internal validity and the statistical information provided (high quality = 6-10, fair quality = 4-5 and poor quality ≤ 3). The quality of the study showed that the mean PEDro score was 6.6 (standard deviation [SD] 1.5), with a range of four to nine points. The Cochrane risk of bias varied. The results showed that seven trials tested the effects of acupuncture on activities of daily living (ADL) according to the Barthel Index: the measurement of the degree of assistance required by an individual on 10 items of mobility and self-care ADL (a higher number being a reflection of greater ability to function independently following hospital discharge), the modified Barthel Index, or the Sunaas Index of ADL. Two of these studies (both from China) showed favourable effects on ADL.34, level I Zhan J et al. (2018) reported that the effect of electro-acupuncture on ADL was analysed using a random-effects model, due to significant heterogeneity in 12 trials with 970 participants. The improvement of ADL in the electro-acupuncture group was better than that in the non-electro-acupuncture group (SMD 1.37, 95% CI: 0.79, 1.96, P<0.00001). In the subgroup analysis (electro-acupuncture plus rehabilitation therapy and conventional drugs versus rehabilitation therapy plus conventional drugs), a random-effects model was used to analyse the effect on ADL due to significant heterogeneity. There was a significant difference between electro-acupuncture combined with rehabilitation therapy and conventional drugs versus rehabilitation therapy plus conventional drugs (WMD 8.03, 95% CI: 5.17, 10.90, p<0.001). Electro-acupuncture plus rehabilitation therapy and conventional drugs for the improvement of ADL was better than that of rehabilitation therapy plus conventional drugs (SMD 1.29, 95% CI: 0.55, 2.02, p<0.001). Meta-analyses with a random-effects model were performed on three trials to evaluate the effect on ADL in this subgroup analysis also owing to statistical

heterogeneity. There was a significant difference in these three trials (WMD 20.90, 95% CI: 18.61, 23.19, p<0.001). In the comparison of electro-acupuncture plus rehabilitation therapy versus rehabilitation therapy alone in the three trials, the improvement in ADL was statistically significant (SMD 1.63, 95% CI: 1.01, 2.25, p<0.00001) (see Figure 12).30, level I

Yang A et al. (2016) reported that, compared with no acupuncture, for people with stroke in the convalescent phase, acupuncture had beneficial effects on the improvement of dependency (ADL) measured by Barthel Index (nine trials, 616 participants; mean difference (MD) 9.19, 95% CI: 4.34, 14.05; GRADE very low).31, level

5.3.4.3. Neurological deficit effect Four trials evaluated the effects of acupuncture on neurologic deficits using the National Institutes of Health Stroke Scale, the European Stroke Scale, or the Scandinavian Stroke Scale. A lower score typically indicated normal function in that specific ability, while a higher score indicated some level of impairment. One of the four studies showed positive therapeutic effects. However, the three trials did not show a significant difference between the two groups (n=216; SMD 0.20, 95% CI: −0.23, 0.62; I2=59%).34, level I Yang A et al. (2016) also reported on neurological deficit effect. Compared with no acupuncture, for people with stroke in the convalescent phase, acupuncture had beneficial effects on the global neurological deficiency (seven trials, 543 participants; odds ratio (OR)=3.89, 95% CI: 1.78, 8.49; GRADE low).31, level I Zhang S et al. (2015) conducted an RCT from April 2001 to February 2002 (pilot phase) and from February 2002 to February 2004 (main study) to assess the efficacy and safety of acupuncture in a more robustly designed larger scale trial.

hundreds and sixty-two adult patients (age 18 to 65 years old) who were diagnosed with acute ischaemic stroke were divided randomly into traditional Chinese acupuncture (plus routine ischaemic stroke treatment) and routine ischaemic stroke treatment control groups, with 427 and 435 in each. The patients were followed up for six months. For the evaluation on neurological deficit, at the end of the scheduled treatment period, there was also a significantly greater change of Scandinavian Stroke Scale score from baseline in acupuncture group (9.70±7.85) than in control group (7.57±12.58; p=0.03), which indicated that patients in acupuncture group had greater reduction in their neurological deficit.35, level I
5.3.4.4. Quality of life (QoL) Kong JC et al. (2010) reported that, of the five trials that assessed the effects of acupuncture treatment on QoL, none showed favourable effects. A meta-analysis of the data from the two studies that involved patients in the chronic stage of stroke (one was excluded due to incomplete data) also did not show favourable effects of acupuncture on function according to the Modified Ashworth Scale: a muscle tone assessment scale used to assess the resistance experienced during passive range of motion, which does not require any instrumentation and is quick to perform; 0 indicates no increase in muscle tone, 4 indicates affected part(s) rigid in flexion or extension, (n=58; MD 0.01, 95% CI: −0.65, 0.67; I2=0%).34, level I Furthermore, there was also no evidence of differences in the changes of QoL between real acupuncture and sham acupuncture for people with stroke in the convalescent stage. However, the score on energy was more favourable in the acupuncture group than in the two other groups, but the differences did not reach statistical significance (see Table 5).33, level I

5.3.4.5. Other parameters A systematic review with meta-analysis was conducted by Wu P et al. (2010) to comprehensively assess the efficacy of acupuncture in post-stroke rehabilitation. The search was done without language restrictions via: MEDLINE, AMED, CINAHL, Alt Health Watch, Nursing and Allied Health Collection: Basic and Cochrane Database of Systematic Reviews, CNKI, CBM up to September 2009. Eligible studies included RCTs that evaluated the clinical efficacy of acupuncture in adult patients (age more

than 18 years old) with disability due either to ischaemic or haemorrhagic stroke. A total of 463 potentially relevant studies were found, of which 56 publications fit the criteria for inclusion. Of those 56 publications, 16 trials used electro-acupuncture, 24 trials used both scalp and body acupuncture, 28 trials used body acupuncture only and four studies used scalp acupuncture only for the treatment groups. The overall quality of the studies was fair and most studies have small sample size (median n=86; range, 16 to 241). In general, randomisation and allocation concealment were poorly reported. Seven studies adequately reported allocation concealment. Assessor blinding was reported in a total of 16 studies.37, level I Positive results were reported in 45 studies. Six studies reported a positive benefit only in a subgroup analysis. No significant differences between acupuncture intervention and control were reported in five studies. Thirty-eight trials provided numeric data for meta-analyses, the results of which yielded a highly significant odd ratio (OR) demonstrating efficacy in post-stroke rehabilitation with acupuncture compared with no acupuncture (OR=4.33, 95% CI: 3.09, 6.08; I2=72.4% (see Figure 13). Randomisation, modes of delivery, method of control, study of source country and reporting of randomisation might explain some of the heterogeneity observed between the studies.37, level I

Berg Balance Scale was conducted to objectively determine a patient's ability (or inability) to safely balance during a series of predetermined tasks. It is a 14 items list with each item consisting of a five-points ordinal scale ranging from zero to four, with zero indicating the lowest level of function and four the highest level of function and takes approximately 20 minutes to complete. It does not include the assessment of gait. The assessment was done in one trial with 120 participants. The improvement of Berg Balance Scale in the electro-acupuncture group was preferable to that in the non-electro-acupuncture group (p<0.050).30, level I Zhang S et al. (2015) reported on death, dependency level and institutional care of the patients at six months. Fewer patients had died or were dependent in the acupuncture group (113/410, 27.6%) than in control group (137/405, 33.0%) at three

months, the tendency continued at six months (80/385 [20.7%] versus 102/396 [25.8%]), but the difference was not statistically significant (OR=0.75; 95% CI: 0.54, 1.05). There was also no significant difference in death or institutional care between the two groups at six months (8.0% versus 7.6%; OR=1.06; 95% CI: 0.63, 1.79). Pre-planned subgroup analysis showed that only when patients who received 10 sessions or more of acupuncture were included in the analysis, a significant difference was detected at six months (57/298 [19.1%] versus 102/396 [25.8%]; OR=0.68; 95% CI: 0.47, 0.98; number needed to treat 15). However, death occurred in 6.2% and 4.5% of patients in the two groups, respectively (OR=1.39%; 95% CI: 0.74, 2.60).35, level I
Compared with no acupuncture, Yang A et al. (2016) reported that acupuncture had beneficial effects on the improvement of cognitive function measured by the Mini-Mental State Examination (five trials, 278 participants; MD2.54, 95% CI: 0.03, 5.05; GRADE very low). Mini-Mental State Examination is a test of cognitive function among the elderly; it includes tests of orientation, attention, memory, language and visual-spatial skills. Hamilton Depression Scale is a multiple item questionnaire used to provide an indication of depression, and as a guide to evaluate recovery. An improvement was reported on depression measured by the Hamilton Depression Scale (six trials, 552 participants; MD: -2.58, 95% CI: -3.28, -1.87; GRADE very low). The swallowing function measured by drinking test (two trials, 200 participants; MD: -1.11, 95% CI: -2.08, -0.14; GRADE very low), and pain measured by the VAS (two trials, 118 participants; MD: -2.88, 95% CI: -3.68, -2.09; GRADE low) also showed some improvements.31, level I
5.3.5. Guillain Barre Only one study reported on efficacy of acupuncture. Rapson LM et al. (2003) conducted a retrospective study to investigate the effects of an EA protocol for the treatment of below-level central neuropathic pain developed at the Toronto Rehabilitation Institute, Lyndhurst Center, Toronto, Ontario, Canada. Patients who were referred to the Lyndhurst Acupuncture Clinic by staff physiatrists were selected. Thirty-six inpatients with spinal cord injury due to traumatic and non-traumatic causes were recruited, however only one patient was diagnosed with Guillain Barre syndrome as a cause of spinal cord injury. The selected patients were divided into electro-acupuncture and non-electro-acupuncture groups. The study described the outcomes of individuals with traumatic and non-traumatic spinal cord injury who were treated according to an electro-acupuncture protocol that was developed at the Lyndhurst Center, called the Lyndhurst Centre Central Neuropathic Pain Acupuncture Protocol (LCCNPAP). The pain ratings were assessed using the 11-points VAS. Two of the authors independently examined each patients’ chart information and identified which pain characteristic(s) applied to each patient. Disagreements were resolved by a third investigator's independent review of the raw data. A significance level of p<0.05 was set for the χ2 statistical analyses. According to patient self-reports, of the 36 patients identified, 24 experienced improvements in response to the LCCNPAP including the only one patient with Guillain Barre syndrome after one treatment. The VAS showed a reduction of pain at discharge which was from seven to two.38

5.3.6. Transverse myelitis (TM) Two studies reported the efficacy of acupuncture. Wu J et al. (2018) conducted a prospective observational study to preliminarily explore the effect of electro-acupuncture on bladder and bowel dysfunction in patients with transverse myelitis. Sixteen patients who had acute or subacute-onset complete or incomplete transverse spinal cord injury, simultaneous bladder and bowel dysfunction or isolated bladder dysfunction caused by transverse myelitis were recruited. Participants were treated with electro-acupuncture at bilateral (BL) BL32, BL33, and BL35 once a day, five times a week for the first four weeks, and once every other day, three times a week for the following four weeks. The patients were then followed up for six months. Bladder and bowel function, and the safety of electro-acupuncture, were assessed. For the assessment of bladder function, after eight weeks of treatment, five (5/16, 31.0%) patients resumed normal voiding, three (6/16, 38.0%) regained partially normal voiding, and five (5/16, 31.0%) had no change. After treatment, the residual urine volume decreased by 100 mL (interquartile range [IQR] 53–393 mL; p<0.05) in nine patients with bladder voiding dysfunction; in 11 patients with urinary incontinence, the number of weekly urinary incontinence episodes, 24-hours urinary episodes, and nocturia episodes per night diminished by 14(95% CI: 5, 22), 5(95% CI: 1, 9), and 4(95% CI: 0, 7) episodes, respectively (all p<0.05) (see Table 6). For bowel function assessment, after eight weeks of treatment in eight patients with faecal retention, four (4/8, 50.0%) resumed normal bowel movements, three (3/8, 38.0%) regained partially normal bowel movements, and one (1/8, 13.0%) had no change. These effects were sustained after six months. The authors concluded that electro-acupuncture might be a promising alternative for the management of bladder and bowel dysfunction in patients with transverse myelitis.39 Table 6: Outcomes for bladder function assessment.39
Rapson LM et al. (2003) reported in retrospective study, the only one patient with transverse myelitis as a cause of spinal cord injury experienced improvement after the two treatments. The VAS showed that the patient could not do scale at discharge due to language difficulty, but the burning pain was reported as much better.38

I Acupuncture was approved by United States of Food and Drug Administration (USFDA) in 1996 and classified as Class II (special control); acupuncture needles must comply with the following special controls:
1. Labeling for single use only and conformance to the requirements for prescription devices set out in 21 CFR 801.109.
2. Device material biocompatibility. 3. Device sterility.42
5.5 Cost analysis and cost-effectiveness There was only one retrievable study on cost-effectiveness and cost-analysis of acupuncture for headache. A multicentre, RCT was conducted by Witt CM et al. (2008) to assess costs and cost-effectiveness of additional acupuncture treatment in patients with headache compared with patients receiving routine care alone. Adult patients; age more and equal than 18 years who were diagnosed with primary headache for more than 12 months and at least having two headaches per month were recruited. The 3182 patients were allocated randomly into acupuncture and control groups, with 1613 and 1569 in each. The International Classification of Diseases (ICD)-10 codes was used to identify costs due only to headache and related conditions. These codes were also provided by the insurance companies for all resources such as days of lost work. In the Germany, an arbitrary and hypothetical threshold of maximum €50000 per quality-adjusted life year (QALY) was used.40, level I For cost-analysis, the mean overall costs incurred by acupuncture patients during the treatment period were €857.47 (95% CI: 790.86, 924.07) and €527.34 (95% CI: 459.81, 594.88) in control patients (p<0.001). Three months after randomisation, the mean cost difference between the two treatment groups [total overall: €330.12 (95% CI: 235.27, 424.98), was primarily due to the acupuncture costs in the acupuncture group [€365.64 (95% CI: 362.19, 369.10)]. In acupuncture patients, the overall cost difference between baseline and the end of the three-month treatment period was €362.05 (95% CI: 293.78, 430.32) compared with €7.05 (95% CI: -62.17, 76.27) in control patients (p<0.001). Excluding the costs of acupuncture revealed that there was no significant overall cost differences between the two study groups. Also in single cost components no significant differences between the two study groups could be detected (see Table 7). Over three-months, costs were higher in the acupuncture group compared with the control [€857.47; 95% CI: 790.86, 924.07, versus €527.34 (459.81, 594.88), p<0.001, MD: €330.12 (235.27, 424.98)]. This cost increase was primarily due to costs of acupuncture [€365.64 (362.19, 369.10)]. The incremental cost-effectiveness ratio (ICER) was €11657 per QALY gained.40, level I

Table 7: Mean costs and cost differences (costs during the three-months treatment period–costs during the three months prior to study initiation) in EURO per patient for acupuncture and control group.40, level I
The cost-effectiveness analysis showed that a gain of 0.0301 ± 0.004 QALYs was observed in the acupuncture group compared with the control group, with additional costs [overall: €350.85 (95% CI: 216.63, 485.07), diagnosis-specific: €365.38 (95% CI: 341.74, 389.02)]. The ICER was €11657 (overall) and €12140 (diagnosis-specific) per QALY gained. Therefore, for the assumed threshold value of €50000, the additional acupuncture intervention would appear to be cost-effective.40, level I Sensitivity analysis reported that for migraine, it was found that acupuncture treatment in men seems to be more cost-effective than in women (ICER men €-810 versus women €19 228). In contrast, for tension-type headache, the acupuncture treatment was more cost effective for women (ICER men €34775 versus women €4109; adjusted ICER men €12599 versus women €2619). The cost acceptability curves represented the probability of cost effectiveness against different threshold values ranging from €0 to €50000 (see Figure 14). The authors concluded that by using acupuncture in addition to routine care to treat patients with primary headache resulted in a marked and clinically relevant benefit and was cost-effective.40, level I

I 5.6 Limitations This review has several limitations. The selection of the studies and appraisal was done by one reviewer. Although there was no restriction in language during the search, only English full text articles were included in the report. The most important limitation was the methodological quality of the included trials which had a high risk of bias. The inappropriate randomised sequence generation, lack of allocation concealment, and an inadequate level of blinding could cause selection or study quality bias. Another weakness is the poor description of patient withdrawals from the studies and the adverse events. There was substantial evidence on acupuncture on headache, Bell’s palsy and post-stroke. However, most of the studies have high risk of bias due to inappropriate randomisation sequence generation, lack of allocation concealment, inadequate level of blinding, poor description of patient withdrawals from the studies and the adverse events and hence, varying the quality of the included trials. Nevertheless, the evidence showed that acupuncture may reduce headache frequency and improve response rate to treatment. The evidence was inconclusive for Bell’s palsy. As for post-stroke patients, the evidence showed acupuncture may improve ADL. As for other outcomes means, the results were inconclusive. For refractory neuralgia, Guillain Barre and transverse myelitis, there was insufficient evidence to assess the efficacy of acupuncture. There were studies reported on adverse events namely, haematoma and ecchymosis,
migraine attacks and headache after treatment, pain and fatigue, seizure, and stomach discomfort. Meanwhile, none of the clinical trials reported any serious adverse events.
6.0 CONCLUSION
MaHTAS Technology Review
32
Acupuncture was approved by United States of Food and Drug Administration (USFDA) in 1996 and classified as Class II (special control). In terms of cost-effectiveness, acupuncture was suggested to have clinically relevant benefit and cost-effective in certain sectors. In Malaysia, the cost per session varies according to scope of treatment ranges between RM35 to RM315. However, acupuncture service is being provided for RM20 per session at Traditional and Complementary Medicine Unit in Ministry of Health hospitals as per Perintah Fi (Perubatan) (Pindaan) 2017..

Study Description
A 102 potentially relevant studies were found, of which
31 publications fit the criteria for inclusion. Of those 31
publications, 16 trials included a sham acupuncture
control group, eight a medication treatment control
group and two a comparator group receiving
physiotherapy.
Study Quality
The quality of the more recent trials was higher than
the previous trials, with more emphasis on proper
randomisation, allocation, concealment and
description of patient dropout.
Outcome Measures

i) Response Rate
Fourteen trials reported data on the proportions of
patients responding to treatment at an early follow-
up period. Combined data demonstrated a
statistically significant higher response rate in the
acupuncture group compared with sham
acupuncture. A significant difference was also
found in subgroup analysis for tension-type
headache. RR was 1.26 (95% CI: 1.10, 1.44)
without heterogeneity (I2=0). However, there was

no significant difference between treatment
groups for migraine.
Only two studies reported the response rate at late
follow-up in which combined data show that RR
was 1.22 (95% CI: 1.04, 1.43), again without
heterogeneity (I2=0).
ii) Headache intensity
Pooled data showed there was no significant
difference between acupuncture and sham groups
at either early follow-up period. Combined data
from three trials in migraine headache also did not
show any difference.
However, combined data from seven at the late
follow-up period showed a WMD of -2.62 mm was
in favour of acupuncture (95% CI: -5.07, -0.17),
whereas data from trials in tension-type headache
showed that acupuncture significantly reduced the
headache score at either the early follow-up or late
follow-up period, where WMD was -3.77 mm (95%
CI: -7.00, -0.55) and -3.66 mm (95% CI: -6.54, -
0.79), respectively.
iii) Health-related QoL
Combined data of four studies showed no
significant difference between acupuncture and
sham acupuncture in both physical and mental
health, in either the early follow up or late follow up
period.

Acupuncture vs medication treatment
i) Headache intensity
Patients receiving acupuncture from two trials
reported significant improvement at the early
follow-up period (WMD: -8.54 mm, 95% CI: -15.52,
-1.57) but the result was heterogeneous.
ii) Headache frequency
Two trials reported the standardized mean
difference in headache frequency was also in
favour of the acupuncture group. Days with
headache per month and attacks (frequency) per
months was -0.22 (95% CI: -0.41, -0.03) and -1.22
(95% CI: -2.34, -0.10) respectively.
iii) Response rate
Pooled data from seven trials showed 62% of
patients receiving acupuncture had a significantly
higher response rate to treatment, compared with
45% of patients receiving medication at the early
follow-up period. RR was 1.80 (95% CI: 1.16,
2.81). This significant difference was also found at
one-year follow-up in one study.
iv) Health-related QoL
Three trial reported suitable data for health-related
QoL in the early-period. Pooled data from three
trials showed that acupuncture produced
significantly better physical function in the early
follow-up period (WMD: 4.16, 95% CI: 1.33, 6.98).

Acupuncture vs physiotherapy (nonpharmalogical
controls)
Three studies found that nonpharmacological
therapies, including physiotherapy and massage
were significantly better than acupuncture for
chronic headache.
A recently published study found similar effects
between acupuncture and physiotherapy for
tension-type headache. However, only one study
reported that patient well-being improved only in
the physiotherapy treatment group.
Conclusion
Acupuncture was more effective for the treatment of
chronic headache when compared with sham
acupuncture and medication treatment.

Randomised Controlled Trial Objective:
To determine the effects of a policy of using acupuncture, compared with a policy of avoiding acupuncture, on headache in primary care patients with chronic headache disorders. Method:
Recruitment took place between November 1999 and January 2001. The evaluation was done on the headache score, medication score, headache days and health status score (using Short Form Survey, SF-36).
I
Adult patients (age 18 – 65 years). Diagnosed as migraine or tension-type headache. 401 patients; 205 acupuncture, 196 no acupuncture.
Acupuncture No acupuncture (usual care)
One year Headache score
In the primary analysis mean headache scores were significantly lower in the acupuncture group. Scores fell by 34% in the acupuncture group compared with 16% in controls (p = 0.0002).
When the pre-specified cut-off of 35% was used as a clinically significant reduction in headache score, 22% more acupuncture patients improved than controls, equivalent to a number needed to treat of 4.6 [95% confidence interval (CI) 9.1 to 3.0].
The effects of acupuncture seemed to be long lasting; although few patients continued to receive acupuncture after the initial 3-month treatment period (25, ten, and six patients received treatment after three, six and nine months respectively), headache scores were lower at 12 months than at the follow-up after treatment.
Medication score
Medication scores at follow-up were lower in the acupuncture group, although differences between groups did not reach statistical significance for all end-points.
Total medication taken by patients after randomisation, weekly use fell by 23% in controls, but by 37% in the acupuncture group (adjusted difference between groups 15%, 95% CI 3 to 27%, p = 0.01).
Headache days
The result showed that differences between groups were not sensitive to the definition of headache day.
Health status score SF-36

SF-36 data generally favoured acupuncture, although differences reached statistical significance only for physical role functioning, energy and change in health.
Conclusion
The study suggested that acupuncture led to persisting, clinically relevant benefits for primary care patients with chronic headache, particularly migraine.

Randomised Controlled Trial Objective:
To investigate the effectiveness of acupuncture compared with sham acupuncture and with no acupuncture in patients with migraine. Method:
The study was held between April 2002 and January 2003 approximately 2000 patients with headaches. The evaluation was done on: Primary outcome: the difference in number of days with headache of moderate or severe intensity; Secondary outcome: the number of migraine attacks, total number of headache days, proportion of treatment responders and days with medication.
I
Adult patients (age 18 – 65 years). Diagnosed with migraine (with or without aura). 302 patients; 145 acupuncture, 81 sham acupuncture, 76 waiting list control.
Acupuncture Sham acupuncture, waiting list control
Primary outcome
Between baseline and week nine to 12 the number of days with headache of moderate or severe intensity decreased by a mean (SD) of 2.2 (2.7) days in the acupuncture group vs 2.2 (2.7) days in the sham acupuncture group and 0.8 (2.2) days in the waiting list group (difference acupuncture vs sham acupuncture, 0.0 days; 95% confidence interval [CI], −0.7 to 0.7 days; P=.96; acupuncture vs waiting list, 1.4 days, 95% CI, 0.8 to 2.1 days; P.001.
Secondary outcome
The proportion of responders (reduction of headache days with moderate or severe pain by at least 50%) was 51% in the acupuncture group, 53% in the sham acupuncture group, and 15% in the waiting list group.
Compared with the waiting list control group, patients receiving acupuncture or sham acupuncture fared significantly better for most secondary outcome measures; however, there were no significant differences between the acupuncture group and the sham acupuncture group.
Response differences in the waiting list group became apparent after the first 4 weeks of treatment and increased until week 12.
Conclusion
Acupuncture was no more effective than sham acupuncture in reducing migraine headaches although both interventions were more effective than a waiting list control.

Randomised Controlled Trial Objective:
To investigate the effectiveness of acupuncture compared with minimal acupuncture and with no acupuncture in patients with tension-type headache. Method:
The investigation took place between March 2002 and January 2004. The evaluation was done on: Primary outcome: the difference in number of days with headache between the four weeks before randomisation and weeks nine to 12 after randomisation. Secondary outcome: headache diary from weeks nine to 12, and pain questionnaire at week 12.
I
Adult patients (age 18 – 65 years). Diagnosed with episodic or chronic tension-type headache. 270 patients; 132 acupuncture, 63 minimal acupuncture, 75 no acupuncture (waiting list).
Acupuncture Minimal acupuncture, no acupuncture
Six months Primary outcome
From baseline to week nine to 12, the number of days with headache decreased by 7.2 (SD 6.5) days in the acupuncture group compared with 6.6 (SD 6.0) days in the minimal acupuncture group and 1.5 (SD 3.7) days in the waiting list group (difference: acupuncture v minimal acupuncture, 0.6 days, 95% confidence interval − 1.5 to 2.6 days, P = 0.58; acupuncture v waiting list, 5.7 days, 4.2 to 7.2 days, P < 0.001).
Secondary outcome
Compared with the waiting list control group, patients receiving acupuncture or minimal acupuncture fared significantly better for most secondary outcome measures; however, no significant differences were found between the acupuncture and the minimal acupuncture group.
The improvements seen in the acupuncture and minimal acupuncture group persisted during the follow-up period. The patients in the waiting list group who received acupuncture in weeks 13 to 20 also showed significant improvements after treatment, although not to the same extent as the patients who had received immediate treatment.
Conclusion
The acupuncture intervention investigated in this trial was more effective than no treatment but not significantly more effective than minimal acupuncture for the treatment of tension-type headache.

Randomised Controlled Trial Objective:
To examine the effect of acupuncture-like electrical stimulation on chronic tension-type headache in a randomised, double-blinded, placebo-controlled study. Method:
The evaluation was done on headache pain description, daily headache duration, average headache intensity, frequency of headache attacks, and use of medication.
I
Adult patients (> 18 years) Diagnosed with chronic tension-type headache. 36 patients; 18 treatment group, 18 placebo group.
Acupuncture Sham acupuncture
Headache pain description
After treatment, 2/36 patients reported that their headache pain had been totally relieved, 4/36 patients felt much better, 7/36 patients felt slightly better, 22/36 patients felt no change, and 1/36 patients felt slightly worse.
Daily headache duration
It indicated a 30% reduction at Treat-1, 17% at Treat-2, and 13% at the end of recording of Post-3 in the treatment group. It also indicated a 14% reduction at Treat-1, 12% at Treat-2, and 12% at the Post-3 in the placebo group.
However, a direct comparison of the changes in headache duration between the treatment and placebo group was not significant (P>0.253) with a change from 8.6 ± 7.4 to 6.0 ± 7.7 (effect size: 0.34; 95% CI: 7.67 to 2.54) in the treatment group and 9.8 ± 8.0 to 8.4 ± 8.9 (effect size: 0.17; 95% CI: 4.34 to 7.14) in the placebo group (effect size: 0.41; 95% CI: 0.11 to 0.45).
In the post-treatment period the differences between the treatment and placebo group became less apparent.
Average headache intensity
The average headache intensity was lower at Treat-1 and Treat-2 compared with the baseline. The pain intensity decreased from 4.9 ± 1.1 to 3.9 ± 1.6 at Treat-1, and to 3.3 ± 1.8 at Treat-2 in the treatment group. The effect size was 0.73 (CI: 1.93 to 0.08) and 1.03 (CI: 2.58 to 0.53).
The pain intensity also decreased from 5.4 ± 1.5 to 5.1 ± 1.7 at Treat-1, and to 5.1 ± 2.0 at Treat-2

in placebo group and the effect size was 0.58 (CI: 0.15 to 2.02).
However, there was no significant difference in pain intensity changes between the two groups (P>0.061). The effect size was 0.57 and the mean difference between group was <16% (CI: -0.03 to 0.34).
Frequency of headache attacks
The number of headache attacks in the two weeks (Treat-1) during the treatment was slightly decreased from 10.5 ± 4.6 to 9.5 ± 5.9 and to 8.4 ± 5.7 in the treatment group. The effect size was 0.47 (CI: 8.08 to 1.48).
There were also slight decreases from 11.5 ± 4.0 to 10.6 ± 3.8 at Treat-1 and to 10.7 ± 3.8 in the placebo group. The effect size was 0.23 (CI: 1.74 to 3.54).
Use of medication
The consumption of analgesics decreased from 26.1 ± 23.3 to 16.9 ± 22.9 at Treat-1 (two weeks) in treatment group. The effect size was 0.40 (CI: 8.10 to 6.44).
There were no apparent changes in analgesic consumption at any stage in the placebo group.
The mean difference between the groups was <34%, and the effect size was 0.57 (CI: -0.75 to 0.06).
The direct comparison between the two groups did, however, not indicate any significant differences (P>0.095).

Randomised Controlled Trial Objective:
To study the comparison of three non-pharmacologic treatments; acupuncture, relaxation training and physical training on subjective well-being patients with chronic tension-type headache. Method:
The evaluation was done on the Minor Symptom Evaluation Profile (MSEP); contentment, vitality and sleep.
I
Adult patients (age 18 - 65 years) Diagnosed with chronic tension-type headache. 88 patients; 29 acupuncture, 30 physical training, 29 relaxation training
Acupuncture Physical training, relaxation training
Six months Between-group comparisons
No difference in MSEP was found immediately after treatment among the 3 treatment groups, when total scores were compared.
At the three-month follow-up, the proportion of individuals with an improved total score was significantly greater in the physical training group compared with the acupuncture group (P=0.036).
At the six-month follow-up, the proportion of individuals with improved levels was maintained in the physical training group and slightly increased in the relaxation training group. No significant differences were found at the six-month follow-up.
Vitality was significantly higher in the relaxation training group compared with the acupuncture group at the six-month follow-up.
Sleep was also significantly higher in the relaxation training group compared with the acupuncture group at the six-month follow-up.
When the contentment dimensions were compared no significant difference was found.
Within-group comparisons
In the acupuncture group (n=30), total MSEP scores of 17 (56.7%) patients were improved immediately after and three and six months after treatment compared with baseline.
In the physical training group (n=30), total scores were improved in 19 patients (63.3%) immediately after training and in 26 (86.7%) and 24 (80.0%) patients at the three-month and six-month follow-ups, respectively, compared with baseline.
In the relaxation training group (n=30), total scores were improved in 23 (76.7%) patients immediately after treatment and in 20 (66.7%) and 22 (73.0%)

Randomised Controlled Trial Objective:
To investigate whether active laser acupuncture reduced headache frequency more effectively than placebo laser acupuncture in children with migraine or tension-type headache. Method:
The study was carried out between October 2006 and March 2007 at two medical centres. The evaluation was done on the headache frequency, duration of headache and pain intensity.
I
Children (age ≤17 years). Diagnosed with unilateral/ bilateral headache or migraine or tension-type headache. 48 patients; 24 active laser acupuncture, 24 placebo laser acupuncture.
Active laser acupuncture
Placebo laser acupuncture
Headache frequency
There was a significant decrease in headache frequency compared to baseline in the active laser treatment group.
The mean improvement in headache frequency was significantly greater in the treatment group than the placebo group.
From baseline to week five to eight, the number of days decreased by 7.0 days in the active acupuncture group compared to 1.2 days in the placebo group.
The difference active acupuncture vs. placebo acupuncture was 5.4 days (p < 0.001).
The decrease in headache frequency in the placebo group was not significant compared to baseline (p = 0.145).
Whereas, the headache frequency in the placebo group reached baseline level in weeks nine to 12, headache frequency in the active acupuncture group stayed low until the study endpoint (p < 0.001).
Duration of headache
There was a significant decrease in monthly headache hours in the active acupuncture group compared to baseline with the mean improvement being greater in the active acupuncture group.
The mild benefit of placebo acupuncture disappeared after eight weeks from baseline whereas the beneficial effect of active laser acupuncture lasted until the end of the follow up.
The monthly headache hours decreased almost solely due to a reduction of the headache frequency.

Pain intensity in the active treatment group decreased significantly compared to baseline.
Again the improvement in the active acupuncture group was greater than in the placebo group.
Nevertheless, there was a significant beneficial effect of placebo laser acupuncture in weeks one to four and 13 to16 from baseline (p = 0.024; p = 0.004).
The effect of the active laser acupuncture on pain severity was weaker than on the above-mentioned parameters but still significantly superior compared to placebo acupuncture at all time points (p < 0.001).
Conclusion
Laser acupuncture could provide a significant benefit for children with headache with active laser treatment being clearly more effective than placebo laser treatment.

Differences with statistical significance between groups appeared in the second month of the treatment in three parameters: number of days with migraine per month (P = 0.006), the total duration of migraine pain in hours per month (P = 0.025), and reduction of ≥40% in the frequency of migraine attacks (P = 0.004).
Greater improvement was observed in the real acupuncture group. From the third month of the treatment to the late post-treatment follow-up, the statistical difference between groups disappeared.
Rescue medication
There was a reduction in the total intake of rescue medications in both groups. However, there were no statistical significant differences between them.
Associated symptoms
There were no statistical significant differences between groups in the associated symptoms (nausea and vomiting).
In the analysis within each group appeared a significant and progressive reduction in the frequency of nausea during migraine attacks in the real acupuncture group from the first month of acupuncture through to the late post-treatment follow-up. The same was not observed in the sham group.
Conclusion
Analysis within each group demonstrated that the sham and real acupuncture had effects in almost all pain parameters evaluated.

Randomised Controlled Trial Objective:
To explore the effectiveness of trigger point dry needling in patients with chronic tension-type headache. Method:
The trial was carried out between April and August 2017. The evaluation was done on the headache intensity, frequency and duration, and health-related quality of life (HRQoL); physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (V), social functioning (SF), role emotional (RE) and mental health (MH).
I
Adult patients (age 20 – 50 years). Diagnosed with chronic tension-type headache. 161 patients; 80 dry needling, 81 sham dry needling.
Dry needling (DN)
Sham dry needling (SDN)
One month Headache intensity, frequency and duration
The result showed a statistically significant differences between measurements in both groups (all P values < .05).
In the DN group, pairwise comparisons revealed that there were statistically significant differences for all headache variables groups (all P values < .05), with the exception of headache duration in the period from post-treatment to follow-up (P=.089).
In the SDN group, pairwise comparisons revealed that there were statistically significant differences for all headache variables (all P values < .05).
HRQoL
A statistically significant differences was showed between the groups on the subscales of PF, RP, BP, V, GH, SF, RE, and MH.
The Mann-Whitney U test revealed statistically significant differences between the groups on the subscales of SF, RF, P, and V. General Linear Model (GLM) revealed statistically significant differences between the groups on the GH, SF, RE, and MH subscales after controlling for the differences of the initial measurements.
Conclusion
The results of this clinical trial suggested that trigger point dry needling in patients with chronic tension-type headache was effective and safe in reducing headache intensity, frequency and duration, and increasing health-related quality of life.

12 months Headache frequency
The frequency of episodes decreased significantly over time (from t0 to t3) (F < time > = 16, 34; df = 3, 84; P < 0.001).
The mean decrease of episode frequency from the baseline period to t3 was 44.3% and 21.4% in acupuncture and placebo-treated patients, respectively.
Headache index
Even the headache index decreased significantly over time (F < time > = 19, 75; df 3, 84; P < 0.0001), but no significance was found for the time/treatment interaction. Between the baseline period and t3, the headache index decreased by a mean of 58.3% and 27.8% in acupuncture and placebo treated patients, respectively
Analgesic consumption
The analgesic consumption decreased significantly over time (F < time > = 10, 09; df = 3, 84; P < 0.0001>, with time x treatment interaction approaching significance (F < time x treatment > = 2. 69; df = 3, 84; P = 0.0513).
In the acupuncture and placebo groups, the mean decrease of analgesic assumption was 57.7% and 21.7%, respectively.
Follow up (six and 12 months)
There were no differences between the two groups relative to intensity and duration of headache episodes, while the frequency of episodes, headache index and consumption of analgesics decreased significantly over time.

Systematic Review with Meta-analysis Objective:
To investigate whether Bell’s palsy patients would benefit from acupuncture treatment comparing with drug therapy. Method:
The search was done without language restrictions via: PUBMED, EMBASE, CENTRAL, CNKI, Wan Fang Database to July 2018. Eligible studies included randomised clinical trials with intervention of acupuncture therapy. Two investigators independently extracted the information from each study. The statistical heterogeneity was set at the I2 statistic >50% and/or Cochrane Q test P<0.10.
I
Patients with Bell’s palsy (facial paralysis/ idiopathic facial paralysis/ herpetic facial paralysis). The 11 RCTs included 1258 patients; 646 in treatment group, 612 in control group.
Manual acupuncture (combined/ not combined with moxibustion)
Drug therapy Study Description
A 323 potentially relevant studies were found, of which 11 publications fit the criteria for inclusion. Of those 11 publications, three trials used acupuncture combined with moxibustion, and the rest eight trials used traditional acupuncture. Study Quality
The results should be interpreted cautiously, because of the poor quality of included studies due to the insufficient information. Risk of Bias of the Trials
Analysis of the risk of bias indicated that the high-risk bias of the included studies was mainly due to the fact that the study process was not blinded or unreported, and assessment of the results were not blinded or unreported. Outcome Measures
Primary outcome: cure rate
The total cure rates for the acupuncture and drug groups were 59.7% and 32.5%, respectively.
Acupuncture treatment was associated with an increased cure rate (RR=1.77, 95% CI: 1.41–2.21, with significant heterogeneity in the pooled results (I2=67%, P=.0008).
Secondary outcome: total effective rate
The total effective rates in the acupuncture and drug groups were 96.9% and 83.0%, respectively.
Acupuncture therapy was associated with an increased total effective rate (RR=1.18, 95% CI: 1.07–1.31, with significant heterogeneity in the pooled results (I2=90%, P<.00001).

Study Description
A 249 potentially relevant studies were found, of which 14 publications fit the criteria for inclusion. Of those 14 publications, five studies used electro-acupuncture technique and nine studies used conventional acupuncture. Study Quality
Almost all studies included were of poor methodological quality. Risk of Bias of the Trials
All the selected studies were considered at high risk of bias or unclear bias. Outcome Measures
Total effective response rate The total effective response rates (13 trials) in the acupuncture and control groups were 95.48% and 82.81%, respectively.

effects were used, depending on the existence of heterogeneity. A value of P less than 0.05 was considered to be statistically significant.
95% CI 1.08–1.20, P < 0.00001; acupuncture group: RR 1.11, 95% CI 1.00–1.24, P = 0.05).
No heterogeneity was found in the (acupuncture plus drug) subgroup (I2 = 19%, P = 0.29). However, there seemed to be huge degree of heterogeneity in the acupuncture versus other intervention subgroup (I2 = 90%, P < 0.00001) and that versus drug therapy subgroup (I2 = 84%, P < 0.00001).
A total of six studies compared (acupuncture) against (drug therapy), and the result showed significant association in these two groups (RR 1.18, 95% CI 1.02–1.36, P = 0.02).
There were three studies compared acupuncture against blank control. However, the meta-analysis of these three studies was unable to perform because two of these studies’ data was unavailable.
Conclusion
The current available evidence was insufficient to support that acupuncture was an effective therapy for Bell’s palsy due to the poor quality of included researches.

Needle Sensation and Personality Factors Influence Therapeutic Effect of Acupuncture for Treating Bell’s Palsy: A Secondary Analysis of Multicentre Randomised Controlled Trial. Chin Med J. 2016; 129: 1789-1794 CHINA
Randomised Controlled Trial Objective:
To find the effects of the traits of personality on the objective outcome when different acupuncture techniques were used in treating patients with Bell’s palsy. Method:
The evaluation was done on the facial nerve function (House-Brackmann [HB] score) and 16 Personality Factor Questionnaire (16PF); Social Boldness Score, Vigilance Score, Tension Score.
I
Adult patients (age 18 – 65 years) with facial nerve weakness. 316 patients; 159 to intervention group, 157 to control group.
Acupuncture with de qi
Acupuncture without de qi
After six months, more patients had complete recovery in de qi group (89.8%) than control group (70.8%) (adjusted for age, gender, treatment center, interval between onset of palsy and start of treatment, HB score on day 1; adjusted odds ratio [OR]: 4.16, 95% confidence interval [CI]: 2.23–7.78).
In de qi group, low HB score on day 1 (OR: 0.13, 95% CI: 0.03–0.45) and low Social Boldness score (OR: 0.63, 95% CI: 0.41–0.97) in 16PF were associated with the better facial function.
In control group, low HB score on day 1 (OR: 0.25, 95% CI: 0.13–0.50) and low Vigilance score (OR: 0.66, 95% CI: 0.50–0.88) and high Tension score (OR: 1.41, 95% CI: 1.12–1.77) in 16PF were associated with better facial function.
The de qi (treatment) group’s score of needle sensation of fullness was 0.58, more than the control group, and the de qi group’s HB score at month 6 was 0.32, less than the control group.
It was found that in both groups, the score of experience and belief in acupuncture questionnaire, gender, age, education status, occupation, and attention had no prominent effects on objective outcome after 6 months.
Conclusion
The needle sensation of fullness could predict better facial function and personality traits might influence outcomes of acupuncture treatment.

Systematic Review with Meta-analysis Objective:
To comprehensively assess the efficacy of acupuncture in post-stroke rehabilitation. Method:
The search was done without language restrictions via: MEDLINE, AMED, CINAHL, Alt Health Watch, Nursing and Allied Health Collection: Basic and Cochrane Database of Systematic Reviews, CNKI, CBM to September 2009. Eligible studies included randomised clinical trials that evaluated the clinical efficacy of acupuncture in adult patients with disability after stroke. Three reviewers assessed eligibility based on the full-text papers and conducted data extraction independently using a standard pre-piloted form.

Study Description
A 463 potentially relevant studies were found, of which 56 publications fit the criteria for inclusion. Of those 56 publications, 16 trials used electro-acupuncture, 24 trials used both scalp and body acupuncture, 28 trials used body acupuncture and four studies used scalp only for the treatment groups. Study Quality
The overall quality of the studies was fair and most studies were small (median n=86; range, 16 to 241). Risk of Bias of the Trials
In general, randomization and allocation concealment were poorly reported. Seven studies adequately reported allocation concealment. Assessor blinding was reported in a total of 16 studies. Outcome Measures
Positive results were reported in 45 studies. Six studies reported a positive benefit only in a subgroup analysis.
No significant differences between acupuncture intervention and control were reported in 5 studies.
Thirty-eight trials provided numeric data for meta-analyses, the results of which yielded a highly significant OR demonstrating efficacy in post-stroke rehabilitation with acupuncture compared with no acupuncture (OR=4.33, 95% CI: 3.09 to 6.08; I2 =72.4%.
Randomisation, modes of delivery, method of control, study of source country and reporting of randomisation might explain some of the heterogeneity observed between the studies

Systematic Review with Meta-analysis Objective:
To summarise and critically evaluate the evidence for and against the effectiveness of contralateral acupuncture (CAT) for post-stroke rehabilitation as compared to ipsilateral acupuncture (IAT). Method:
The search was done without language restrictions via: MEDLINE, EMBASE, CINAHL, AMED, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Methodology Register, a Chinese medical database (CNKI), three Japanese medical databases, six Korean medical databases, and four major Korean traditional medical journals to June 2010.

Post-stroke hemiplegic patients. The eight RCTs included 534 patients; six trials followed two-arm parallel group design, two trials followed four-arm parallel group design.
CAT (electro-acupuncture [EA]/ manual acupuncture)
IAT (electro-acupuncture [EA]/ manual acupuncture)
Study Description
A 119 potentially relevant studies were found, of which eight publications fit the criteria for inclusion. Of those eight publications, four of the RCTs included subjects with cerebral infarction, while the other four included subjects with either cerebral infarction or intracranial hemorrhage. Study Quality
Patient blinding was assumed when the control intervention was indistinguishable from acupuncture, even if the word “blinding” was not used in the report. Risk of Bias of the Trials
Three of the included RCTs described the sequence generation and they all used proper methods. It was not clear whether group assignment was adequately concealed in any of the included trials. All of the included trials were rated as ‘U’ or ‘N’ for patient blinding, and two studies were rated as ‘Y’ for outcome assessor blinding. For incomplete outcome data reporting, one study did not clearly report how many patients were analysed. (Y=Yes, N=No, U=Unclear). Outcome Measures
Response rate
Six of the included trials examined the effects of CAT as compared to IAT on response rate. Only one trial showed a favourable effect of CAT.
A meta-analysis, however, showed that CAT had superior effects compared to IAT on response rate (n = 361; RR, 1.12; 95% CIs, 1.04 to 1.22, P = 0.005; heterogeneity: χ2 = 2.71, P = 0.75, I2 = 0%).

General comments
Eligible studies included prospective randomized clinical trials comparing the clinical effects of CAT to those of IAT. Disagreements were resolved by discussion between the two reviewers. The data was pooled across studies using a random effects model (when appropriate). The chi square, tau2 and Higgins I2 tests were used to assess heterogeneity.
Subgroup analysis also showed favourable effects of CAT for patients with cerebral infarction (n = 261; RR, 1.15; 95% CIs, 1.04 to 1.27, P = 0.006; heterogeneity: χ2 = 0.65, P = 0.88, I2 = 0%).
Further analysis including patients with cerebral infarction and intracranial hemorrhage, however, failed to find these favourable effects (n = 100; RR, 1.11; 95% CIs 0.85 to 1.46, P = 0.43; heterogeneity: χ2 = 1.78, P = 0.18, I2 = 44%).
Activities of Daily Living (ADL)
Three of the RCTs assessed the effects of CAT on ADL compared to IAT. Only one trial showed favourable effects of CAT.
A meta-analysis of these studies failed to show superior effects for CAT compared to IAT with regard to ADL (n = 193; SMD, 0.17; 95% CIs, -0.20 to 0.54, P = 0.37; heterogeneity: χ2 = 4.65, P = 0.20, I2 = 36%).
Neurological Deficit Score (NDS)
Two of the RCTs assessed the effects of EA-CAT compared to EA-IAT on NDS. Only one trial showed the significant superior effects of EA-CAT.
A meta-analysis failed to show significant difference between the two methods (n = 121; WMD, 2.23; 95% CIs, -1.35 to 5.77, P = 0.22; heterogeneity: χ2 = 2.48, P = 0.12, I2 = 60%).
Motor function

Systematic Review with Meta-analysis Objective:
To assess the effectiveness and safety of electro-acupuncture (EA) combined with rehabilitation therapy (RT) and/or conventional drugs (CD) for improving post-stroke motor dysfunction (PSMD). Method:
The search was done via: the China National Knowledge Infrastructure, Chinese Biological Medicine Database, Chinese Scientific Journal Database (VIP), Cochrane Library, MEDLINE, EMBASE, PUBMED and Cochrane to December 2016. Two authors independently extracted information from the included trials. The information was entered into an Excel-formatted table.
I
Adult patients (age > 18 years). Patients with acute stage of stroke (onset of the first stroke with motor dysfunction). The 19 RCTs included 1434 patients; all trials were conducted in China.
Electro-acupuncture (EA)
Non EA Study Description
A 892 potentially relevant studies were found, of which 19 publications fit the criteria for inclusion. Of those 19 publications, 16 trials compared (EA plus CD and RT) with (CD plus RT). Three trials gave EA and RT to the experimental groups, while the control groups only received RT. Study Quality
Most of the included trials had methodological defects, and the funnel plots of Fugl-Meyer Assessment Scale (FMA) and Activities of Daily Living (ADL) suggested a potential publication bias. These issues potentially lead to low quality of evidence. Risk of Bias of the Trials
Thirteen trials and 12 trials respectively showed a difference in FMA and ADL between the EA and the non-EA groups.
Outcome Measures Primary outcomes
Fugl-Meyer Assessment Scale (FMA)
The outcome was mentioned in 13 trials with 1010 patients.
There were no significant differences in treatment duration in the meta-regression model (adjusted R2: 0.124, t=−1.57, P=0.144).
The FMA score in the EA group increased more than those in the non-EA group, and there was a significant difference (WMD 10.79, 95%CI 6.39 to 15.20, P<0.001).

General comments
A fixed-effects model was chosen to pool the data (for insignificant heterogeneity); otherwise, a random-effects model was used after considering clinical homogeneity.
One trial with 98 participants used the FMA for upper extremity to evaluate the function of the upper extremity, and the difference between the EA group and the non-EA group was obvious (P<0.050).
FMA for lower extremity (FMA-L)
The function of the lower extremity was assessed in four trials with 234 participants. There was a significant difference between the EA group and the non-EA group in the FMA-L (WMD 5.16, 95%CI 3.78 to 6.54, P<0.001).

Activities of Daily Living (ADL)
The effect of EA on ADL was analysed using a random-effects model, due to significant heterogeneity in 12 trials with 970 participants.
The improvement of ADL in the EA group was better than that in the non-EA group (SMD 1.37, 95%CI 0.79 to 1.96, P<0.00001).
Response/ Effective rate (ER)
Two trials with a total of 171 participants showed that there was no significant difference in ER between EA and non-EA groups (RR 1.13, 95%CI 1.00 to 1.27, P=0.050; fixed-effects model).
Berg Balance Scale (BBS)
The assessment was done in one trial with 120 participants. The improvement of BBS in the EA group was preferable to that in the non-EA group (P<0.050).

Subgroup analysis (EA plus RT and CD) versus (RT plus CD)
Ten trials used FMA to measure the motor function of 796 participants with PSMD. A random-effects model was used to analyse the effect on FMA and ADL in this subgroup analysis due to significant heterogeneity.
There was a significant difference between (EA combined with RT and CD) versus (RT plus CD) (WMD 8.03, 95%CI 5.17 to 10.90, P<0.001).
(EA plus RT and CD) for the improvement of ADL was better than that of (RT plus CD) (SMD 1.29, 95%CI 0.55 to 2.02, P<0.001).
(EA plus RT) versus (RT alone)
Three trials with 214 participants applied FMA to compare the effectiveness of (EA plus RT) against (RT alone). Meta-analyses with a random-effects model were performed to evaluate the effect on FMA and ADL in this subgroup analysis owing to statistical heterogeneity. There was a significant difference in these three trials (WMD 20.90, 95%CI 18.61 to 23.19, P<0.001).
In the comparison of (EA plus RT) versus (RT alone) in the three trials, the difference in ADL was obvious (SMD 1.63, 95%CI 1.01 to 2.25, P<0.00001).
Conclusion
EA as a complementary therapy seemed to have clinical benefits in terms of improving the function of extremities, ADL and balance function.

> Three months
Study Description
A 5874 potentially relevant studies were found, of which 31 publications fit the criteria for inclusion. Of those 31 publications, two trials compared real acupuncture plus baseline treatment with sham acupuncture plus baseline treatment, and the remaining 29 trials compared acupuncture plus baseline medication or treatment with baseline medication or treatment alone. Study Quality
The methodological quality of most of the included trials was not high. The quality of evidence for the main outcomes was low or very low based on the assessment by the system of Grades of Recommendation, Assessment, Development and Evaluation (GRADE). Risk of Bias of the Trials
Many studies did not provide detailed information on the severity of the disease, the exact time of starting the acupuncture treatment, the modalities of acupuncture technique and acupuncturist's background, and possible adverse effects relevant to acupuncture treatment.
Publication bias might be present, as indicated by the asymmetric funnel plot for the effect of acupuncture on the improvement of dependency measured by the Barthel Index.
Outcome Measures
Real acupuncture plus baseline treatment with sham acupuncture plus baseline treatment
There was no evidence of differences in the changes of motor function and quality of life

Systematic Review Objective:
To determine whether complex Traditional Chinese Medicine (cTCM) treatments improves post-stroke motor recovery. Method:
The search was done via: PubMed, EMBASE, CBM, the Cochrane Library, and other Chinese journal databases to December 2007. Two reviewers independently examined titles and abstracts of the trials for inclusion, based on the selection criteria outlined. Statistical analysis was performed using software provided by the Cochrane Collaboration (Review Manager 5).
I
Patients with ischaemic or haemorrhagic stroke. The 34 RCTs included 4521 patients; 11 trials included patients with ischemic stroke only, 23 included patients with ischemic and hemorrhagic stroke.
cTCM Acupuncture (with/ without physical exercise)
Study Description
A 11235 potentially relevant studies were found, of which 34 publications fit the criteria for inclusion. All the included studies were single-center, parallel-design and randomised. Study Quality
In general, the methodological quality of the trials included was poor. According to the Cochrane handbook, all of the trials included were of low quality classified as “C”. Risk of Bias of the Trials
A strong publication bias was present in the review as the asymmetry of the funnel plot was reported. Outcome Measures
Effective Rate Ratio (ERR): cTCMs Versus Acupuncture
Four of the 12 trials of cTCM versus acupuncture alone showed statistically significant higher ERR after treatment with the cTCM ([ERR, 1.37: 95% CI, 1.02 to 1.85], [ERR, 1.38; 95% CI, 1.06 to 1.80], [ERR, 1.57; 95% CI, 1.18 to 2.08], [ERR, 1.11: 95% CI, 1.03 to 1.20]).
The remaining eight trials did not show statistically significant differences between the experimental and control groups.
In two other trials the control group included acupuncture plus physical exercise, only one showed a statistically significant result (ERR, 1.16; 95% CI, 1.04 to 1.31).

7. Sze FKH, Wong E, Yi X, Woo J. Does Acupuncture Have Additional Value to Standard Poststroke Motor Rehabilitation? Stroke. 2002; 33: 186-194 CHINA
Randomised Controlled Trial Objective:
To examine whether acupuncture has additional value to standard post-stroke motor rehabilitation. Method:
The evaluation was done on the Fugl-Meyer Assessment of Physical Performance (FMA), Barthel Index (BI), Functional Independence Measure (FIM), Abbreviated Mental Test (AMT), and NIH Stroke Scale (NIHSS).
I
Chinese patients with hemorrhagic or ischemic stroke. 106 patients; 31 to group 1A and 1B, 22 to group 2A and 2B. Group 1: Received five weeks (± 1 week) of inpatient rehabilitation, followed by five weeks (± 1 week) of day hospital rehabilitation. Group 2: Received three weeks (± 1 week) of inpatient rehabilitation, followed by seven weeks (± 1 week) of day hospital rehabilitation. Group A: intervention group. Group B: control group.
Traditional Chinese manual acupuncture
No acupuncture
No differences were seen between the intervention arm and the control arm in either group 1 or group 2, when comparing impairment scores of FMAM and FMA, or disability scores of FIM-cognition, FIM-motor, FIM, and BI at 10 weeks.
The median score changes of FMAM, FMA, FIM-cognitive, FIM-motor, FIM, and BI over 10 weeks from baseline also did not show statistical difference between the two arms.
In fact, both arms showed similar improvement in motor impairment and disability, and the improvement was faster in the first five weeks.
Conclusion
Traditional Chinese manual acupuncture on the body has no additional value to standard post-stroke motor rehabilitation.

Six months Primary outcome
Death/ dependency at six months
Fewer patients had died or were in the acupuncture group (113/410, 27.6%) than in control group (137/405, 33%) at three months, the tendency continued at six months (80/385 [20.7%] versus 102/396 [25.8%]), but the difference was not statistically significant (OR, 0.75; 95% CI, 0.54–1.05).
Death/ institutional care at six months
There was also no significant difference in death or institutional care between the two groups at six months (8.0% versus 7.6%; OR, 1.06; 95% CI, 0.63–1.79).
Pre-planned subgroup analysis showed that only when patients who received ≥10 sessions of acupuncture were included into analysis, a significant difference was detected at six months (57/298 [19.1%] versus 102/396 [25.8%]; OR, 0.68; 95% CI, 0.47–0.98; number needed to treat 15).
Secondary outcome
Death at six months
Death occurred in 6.2% and 4.5% of patients in the two groups, respectively (OR, 1.39%; 95% CI, 0.74–2.60).
Neurological deficit score
At the end of the scheduled treatment period, there was significantly greater change of Scandinavian Stroke Scale score from baseline in acupuncture group (9.70±7.85) than in control group (7.57±12.58; P=0.03), which indicated that

Randomised Controlled Trial Objective:
To study effects of acupuncture and transcutaneous electrical nerve stimulation (TENS) on functional outcome and quality of life after stroke versus a control group that received subliminal electrostimulation. Method:
The evaluation was done on activities of daily living (ADL) (used Barthel Index [BI]), overall motor function (used Rivermead Mobility Index), fine motor function (used Nine Hole Peg Test), and quality of life (QoL) (used Nottingham Health Profile).
I
Patients with acute stroke. 150 patients; 48 allocated to acupuncture group, 51 allocated to TENS group, 51 to subliminal (control) group.
Acupuncture TENS, subliminal electrostimulation
12 months Overall motor function In intention-to-treat analyses, no clinically meaningful or statistically significant differences existed in overall motor function. Fine motor function Most patients in all groups were unable to score more than zero in the Nine Hole Peg Test, which was used to assess fine motor function of the affected hand. Barthel’s ADL Index Neither at three or 12-months follow-up did any statistically significant differences occur between the three groups. QoL The score on energy was more favourable in the acupuncture group than in the two other groups, but the differences did to not reach statistical significance. Conclusion
When compared with a control group that received subliminal electrostimulation, treatment during the subacute phase of stroke with acupuncture or transcutaneous electrical nerve stimulation with muscle contractions had no beneficial effects on functional outcome or life satisfaction.

Prospective Observational Study Objective:
To preliminarily explore the effect of electro-acupuncture (EA) on bladder and bowel dysfunction in patients with transverse myelitis (TM). Method:
Participants were treated with EA at bilateral BL32, BL33, and BL35 once a day, five times a week for the first four weeks, and once every other day, three times a week for the following four weeks. Patients were then followed up for six months. Bladder and bowel function, and the safety of EA, were assessed.
Sixteen patients: Had acute or subacute-onset complete or incomplete transverse spinal cord injury; Had simultaneous bladder and bowel dysfunction or isolated bladder dysfunction caused by TM.
Electro-acupuncture
Six months Assessment of bladder function
After eight weeks of treatment, five (5/16, 31%) patients resumed normal voiding, three (6/16, 38%) regained partially normal voiding, and five (5/16, 31%) had no change.
After treatment, the residual urine volume decreased by 100 mL (IQR 53–393 mL; P<0.05) in nine patients with bladder voiding dysfunction; in 11 patients with urinary incontinence, the number of weekly urinary incontinence episodes, 24-hour urinary episodes, and nocturia episodes per night diminished by 14 (95% CI 5 to 22), 5 (95% CI 1 to 9), and 4 (95% CI 0 to 7) episodes, respectively (all P<0.05).
Assessment of bowel function
After eight weeks of treatment in eight patients with faecal retention, four (4/8, 50%) resumed normal bowel movements, three (3/8, 38%) regained partially normal bowel movements, and one (1/8, 13%) had no change. These effects were sustained after six months.
Conclusion
EA might be a promising alternative for the management of bladder and bowel dysfunction in patients with transverse myelitis.

Cost effectiveness and cost analysis Objective:
To assess costs and cost-effectiveness of additional acupuncture treatment in patients with headache compared with patients receiving routine care alone. Method:
The multicentre, randomised controlled trial was carried out. The International Classification of Diseases (ICD)-10 was used to identify costs due only to headache and related conditions. In the Germany, an arbitrary and hypothetical threshold of maximum €50000 per QALY was used.
Adult patients (age ≥ 18 years). Diagnosed with primary headache (>12 months) and at least two headaches per month. 3182 patients; 1613 acupuncture, 1569 controls.
Acupuncture + routine care
Routine care alone
Cost analysis
The mean overall costs incurred by acupuncture patients during the treatment period were €857.47 (95% CI 790.86, 924.07) and €527.34 (95% CI 459.81, 594.88) in control patients (P < 0.001).
Three months after randomization, the mean cost difference between the two treatment groups [total overall: €330.12 (95% CI 235.27, 424.98), was primarily due to the acupuncture costs in the acupuncture group [€365.64 (95% CI 362.19, 369.10)].
In acupuncture patients, the overall cost difference between baseline and the end of the three-month treatment period was €362.05 (95% CI 293.78, 430.32) compared with €7.05 (95% CI -62.17, 76.27) in control patients (P < 0.001).
Excluding the costs of acupuncture reveals that there were no significant overall cost differences between the two study groups. Also in single cost components no significant differences between the two study groups could be detected.
Over three-months costs were higher in the acupuncture group compared with the control [€857.47; 95% confidence interval 790.86, 924.07, vs. €527.34 (459.81, 594.88), P < 0.001, mean difference: €330.12 (235.27, 424.98)]. This cost increase was primarily due to costs of acupuncture [€365.64 (362.19, 369.10)]. The ICER was €11 657 per QALY gained.
Cost effectiveness analysis
A gain of 0.0301 ± 0.004 QALYs was observed in the acupuncture group compared with the control group.

General comments
However, this gain was associated with additional costs [overall: €350.85 (95% CI 216.63, 485.07), diagnosis-specific: €365.38 (95% CI 341.74, 389.02)]. The ICER was €11657 (overall) and €12140 (diagnosis-specific) per QALY gained. Therefore, for the assumed threshold value of €50000, the additional acupuncture intervention would appear to be cost-effective.
Sensitivity analysis
For migraine it was found that acupuncture treatment in men seems to be more cost-effective than in women (ICER men €-810 versus women €19 228).
In contrast, a reverse situation was observed for tension-type headache (TTH). Therefore, the acupuncture treatment was assessed as a more cost effective treatment for women (ICER men €34775 versus women €4109; adjusted ICER men €12599 versus women €2619).
The cost acceptability curves represented the probability of cost effectiveness against different threshold values ranging from €0 to €50 000. In female patients, acupuncture treatment reaches a maximum overall cost effectiveness probability of approximately 100% versus a probability of approximately nearly 100% (98.8%) in men
Conclusion
This study has shown that using acupuncture in addition to routine care to treat patients with primary headache resulted in a marked and clinically relevant benefit and was cost-effective.
