• Written for the public

• Describes in easy to understand language what happens when we adjust a VS

[email protected]

Where are you at now?

In pairs (one being the chiro, the other the patient) each take turns explaining:

What a subluxation is

How chiropractic care works

How did that go?

Where you confident?

Do you know if your ‘story’ has scientific backing?

The big picture

In a nutshell

What is a subluxation?

How does chiropractic care work?

A subluxation is.....

“a central segmental motor control problem”

Which means that the central nervous system is notcontrolling the movement pattern of the spinalsegment as it should, which alters the stretching ofthe paraspinal muscles which changes the input to thebrain which impacts how it processes otherinformation

So that it can accurately perceive what is going on and respond

appropriately

which in turn improves the communication between your brain,

the body and the environment

Chiropractic is a healing art that improves the health and function of

the spine

Wisdom vs Knowledge

When talking about the chiro-relevant scientific studies:

1. This is what they did

2. This is what they found

3. This is what that possible means to you

4. BUT..... (mention limitations with study for you patient)

My potential role

Help you communicate about the key neuroscience concepts vital to understand how chiro care likely works

Help you to understand and communicate about the chiropractic relevant neuroscience research

To patients, the public, and to other health care providers

Help you to understand and communicate about the chiropractic relevant neuroscience research specific to particular groups

Sports, paediatric, asymptomatic,

What I can help you with

Various topics:

Research and science

Difference between different research methods

Evidence based practice

The Brain & CNS 101

The Matrix

Principles of Neural Science by Eric R. Kandel, James H. Schwartz, and Thomas M. Jessell. Elsevier, 2000, 4th Ed, Ch 33, p. 654

“IN THE PRECEDING PART of this book we considered how the brain constructs internal representations of the world by integrating information from the different sensory systems.

These sensory representations are the framework in which the motor systems plan, coordinate, and execute the motor programs responsible for purposeful movement.”

This is SENSORI-MOTOR-INTEGRATION

This is MULTI-MODAL-INTEGRATION

In pairs, take turns explaining to each other the following concepts:

Multimodal integration and the inner brain reality

Sensorimotor integration and its importance for accurate purposeful movements

How did that go?


Did any questions arise?

The inner brain realityis it always accurate?

Phantom limb pain

Central filtering of info

Sensory information in the central nervous system is processed in stages, in the sequential relay nuclei of the spinal cord, brain stem, thalamus, and cerebral cortex. Each of these processing stations brings together sensory inputs from adjacent receptors and—using networks of inhibitory neurons—transforms the information to emphasize the strongest signals.

Kandel, Schwartz, and Jessell, 2000, p.428

“We are continuously exposed to stimulation across our senses; some of which is relevant to the task at hand but most of which is not. The ability to isolate and process appropriate sensory stimulation whilst inhibiting irrelevant stimulation is essential in order to achieve our goals in a timely and efficient manner. However as we age it is thought that the inhibition of irrelevant information becomes more difficult such that available sensory information is processed more extensively.”

(Setti et al 2011, Experimental Brain Research, 209;p.379)

Brain fills in the gaps and/or alters your reality based on past expectations, surrounding information and intentions.

Pain and Plasticity

“We can mess with that”

Blind spot testing

Neural plasticity

Neural Plasticity

“Many important behaviors are learned. Indeed, we are who we are largely because of what we learn and what we remember. We learn the motor skills that allow us to master our environment, and we learn languages that enable us to communicate what we have learned, thereby transmitting cultures that can be maintained over generations. But not all learning is beneficial. Learning also produces dysfunctional behaviors, and these behaviors can, in the extreme, constitute psychological disorders.”

Kandel, Schwartz, and Jessell, 2000, p.1228

Maladaptive vs Adaptive Plasticity

Symptoms don’t just appear out of thin air

Neuroscience concepts covered:

CSN, PNS, neurons, synapses, networks Internal representations

– Internal body schema– Inner Matrix

Problems with false internal body schema– Phantom limb pain, tinnitus, and on smaller

scale Central filtering Brain filling in the gaps (blind spot) Neural plasticity (good and bad) Sensorimotor integration and movement control

The connection between the neuroscience and chiropractic!

Paraspinal Muscles act as CNS sensors

Spinal muscle afferents are important for the brain sensory integration of other afferent input

Aberrant spinal movement

Can mean that the brain may not be fully aware of what is going on in your spine, which appears to influence how it controls the rest of the body

– Growing body of research supports this!

May impact the accuracy of our Matrix

– Theory, but with some evidence that suggests this

Spinal function impacts integration of sensory information

Growing body of research supports this!

This could lead to accidents, the develop pain and dysfunction, syndromes, conditions, etc.

So that it can accurately perceive what is going on and respond

appropriately

which in turn helps clear up the communication between your brain,

the body and the environment

Chiropractic care improves the health and function of the spine

The floor-plan research methodology analogy

Systematic Reviews

Editorials, Expert Opinion

Randomised Controlled Trials

Cohort Studies

Case-control Studies

Case Series, Case Reports

The hierarchy of evidence

Turn to your neighbour and explain the difference between basic science and clinical science and answer the following:

1. How can you tell the difference between basic science and clinical science? What evidence do each provide?

2. Can you think of some difficulties scientist have when doing research into the subluxations and effects of adjusting them?

3. What is the key difficulty when trying to do clinical science with a chiropractic intervention?

4. What is the benefit to you with good chiropractic basic science?

5. What is the benefit to you with positive chiropractic clinical science?

2. Issues for scientists wishing to explore the subluxation and the effects of the adjustment

An intervention is supposed to be properly defined and repeatable

– What is a subluxation?

– How do you find one?

– Can you find them reliably?

– What is the spinal manipulation / adjustment intervention?

– Can it be repeated in a reliable manner?

3. What is the key difficulty when trying to do clinical science with a chiropractic intervention?

Clinical research is about the effects of an intervention on a particular condition

So what (conditions) does chiropractic treat?

Afternoon Tea

3.00 – 3.45

Lets get stuck into some studies

Clinical research

Read and be able to discuss the RCTs and reviews that demonstrate spinal manipulation is as good as anything else out there for

– Back pain (E.g. UK BEAM study 2004 BMJ; LBP Brontfort et al 2008; AM-LBP - Bishop et al 2010)

– Neck pain (Haldeman S, Carroll L et al. (2008) The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders; Executive Summary, Spine 33(4S):S5-S7)

– Headaches (See review in The chiropractic report Sept 2010)

Clinical research

And that chiro patient satisfaction is MUCH better than other care (See review in The chiropractic report Jan 2007)

And we are more cost effective (See review in The chiropractic report Nov 2009)

And we are safe (Cassidy JD, Boyle, E, Cote et al. 2008 Risk of Vertebrobasilar Stroke and Chiropractic Care: Results of a Population-Based Case-Control and Case-Crossover Study, SPINE 33(4S): S176-183)

There is even evidence for maintenance care for low back pain (Senna MK, Machaly SA. 2011. Does Maintained Spinal Manipulation Therapy for Chronic Non-Specific Low-Back Pain Result in Better Long Term Outcome? SPINE)

In groups of 3 practice telling your patient about the clinical research there is about chiropractic

See if you can turn the subject’s attention from the clinical research to the basic science research in simple language

Pre Adjustments

Post Adjustments

17/90 impaired FFA

13/17 retested 6 month later

38% improvement in FFA times after SI adjustments

Example 1

This is what they did and this is what they found:– They tested 90 healthy young male cricket players in their ability to feed-forward

activate their abdominal muscles - 19/90 could not– Six months later 13/17 still could not– One adjustment session – 40% improvement

This is what this means to you– You may not be able to feed forward activate your core abdominal muscles– These are important low back support mechanism for you– If you cannot you are basically causing mini low back whiplash each time you lift

your arm– No symptoms in those guys, so you may not have felt it either – so can be why

your low back pain started.... You said you did not know why – We know being unable to activate core muscles leads to LBP

Caution/Limitations.......... ‘BUT...’– You are a woman, the study was only on men– We dont know how long the effects last, was only one pre/post

Practice this

In groups of three (chiro, patient, assessor) practice telling a patient about this study. Remember:– What did they do– What did they find– What does this mean to your patient– But....limitations of study

Swap around so everyone has a go at being chiro Assessors: please provide feedback to chiropractor! Patient:

– create a story for the chiro (e.g. I’m a 48 female with LBP)– And ask questions like – why did I get low back pain, I

had no injury, it just happened, why would chiropractic work for me?

How did that go?


What was easy?

What was hard?


Example 2

This is what they did and this is what they found:– Twenty-five SCNP participants and 18 control participants were tested for their elbow

JPS before to see if SCNP participants JSP was worse than controls – and they were!– The SCNP group then were retested after either SM or control intervention. SM

improved elbow JPS!!

This is what this means to you– If your brain is not fully aware of where your elbow is, it could be why you keep

knocking it in doorframes– This study suggests that spinal function impacts how accurately your brain can

interpret propriocpetive information from your arms

Caution/Limitations.......... ‘BUT...’– You are a older than the individuals in this particular study, although there is an study

done in 65 + year olds done with anckle JPS and they improved significantly over a four week period

– We dont know how long the effects last, was only one pre/post– The anckle study showed effects of 12 weeks chiro care, but no follow up done

Practice this

In groups of three (chiro, patient, assessor) practice telling a patient about this study. Remember:– What did they do– What did they find– What does this mean to your patient– But....limitations of study

Swap around so everyone has a go at being chiro Assessors: please provide feedback to chiropractor! Patient:

– create a story for the chiro (e.g. I’m a 48 female with LBP)– And as questions like – why did I get low back pain, i had

no injury, it just happened, why would chiropractic work for me?

How did that go?
