Introduction Exercise as an intervention has been
suggested as having the potential to improve sleep quality (Sherrill DL, et al;1998).
In large surveys, up to 80% of people spontaneously report exercise as a factor that promotes sleep quality (Shapiro CM, et al ;1988)

Introduction
Poor sleep quality is a common and distressing problem for cancer patients.
Patients with cancer often report that their sleep is disturbed during the stressful periods associated with diagnosis, treatment side effects, and physical discomfort (Espie CA, et al ;2008).
![Page 5: Improving Sleep Quality for Cancer Patients: Benefits of a Home-Based Exercise Intervention](https://reader035.vdocuments.net/reader035/viewer/2022062518/56814453550346895db0ef78/html5/thumbnails/5.jpg)
Introduction
Payne et al.(2008) allocated 20 women with breast cancer who were receiving hormonal treatment to usual care or a home-based walking exercise Intervention.
Self-reported sleep quality improved in the exercise group.
![Page 6: Improving Sleep Quality for Cancer Patients: Benefits of a Home-Based Exercise Intervention](https://reader035.vdocuments.net/reader035/viewer/2022062518/56814453550346895db0ef78/html5/thumbnails/6.jpg)
Purpose
1) To determine the effect of a home-based walking exercise program on the sleep quality and quality of life of cancer patients.
2)To determine if enhanced sleep quality was associated with improvement in quality of life over time.

Hypothesized
A home-based walking exercise would have beneficial effects on sleep quality and quality of life.

A home-based walking exercise for cancer patients on sleep quality and quality of life.
Participants were allocated either to usual care (n = 35) or the walking exercise intervention group (n = 36).

Methods -- Exercise training booklet
The 8-week time period was based on previous exercise research among cancer patients.
Patients were instructed to walk at a pace that was faster than normal and based on ratings of perceived exertion (RPE; 11–13).
![Page 14: Improving Sleep Quality for Cancer Patients: Benefits of a Home-Based Exercise Intervention](https://reader035.vdocuments.net/reader035/viewer/2022062518/56814453550346895db0ef78/html5/thumbnails/14.jpg)
Methods -- Exercise training booklet
Three days a week, for 30 minutes a day in the evening before supper(4:00 p.m. to 6:00 p.m.).
A five-minute warm up and finish with a five-minute cool down, after completing the 30-minute walking program.

Procedure Patients were informed consent a baseline
assessment . Randomly assigned to either the
experimental or control group . Data collect from each patient during the
initial visit (baseline) and two follow-up visits(1 and 2 months).

Results
Patients in the exercise group reported significant improvements in sleep quality (β=−3.54, p<0.01)
Among patients who exercised, enhanced sleep quality also corresponded with reduced bodily pain (β=0.98,p=0.04)
Improvements over time in the mental health
dimension of quality of life (β=−3.87, p<0.01).

Conclusions
A home-based walking exercise program can be easily incorporated into care for cancer patients who are suffering from sleep disturbances.
Home-based walking exercise program improves sleep quality and quality of life.

Conclusions
Improvements in quality of life may in part be mediated by sleep.
Enhanced sleep quality also contributed to reduce bodily pain and improvements in the mental health dimension of quality of life.
