Regression to the Mean and Massage

Regression to the Mean and Massage

Or “I’m not as good as I think I am”

As a massage therapist, you become aware that there are a
multitude of different techniques, styles and modalities that are being
taught.  There are proprietary names,
three letter acronyms and jargon, jargon, jargon. 

There is a growing awareness that the narratives espoused by
most of these courses are just plain wrong and that those teaching the courses
could be argued are deluded about how their manual therapy techniques are
affecting the body. 

Some therapists are happy to carry on doing what they’ve
always been doing and believing everything that they have been taught.  And it is quite understandable because they
often achieve good results for their clients and their clients keep returning.  If it ain’t broken, why fix it?

Other (and may I dare to say) more discerning and learned therapists can become challenged by the realisation that they are not changing soft tissue structures.  To quote from

“You’re treating a person, not a skeleton with muscles,
tendons, ligaments and fascia”

I had a fairly heated online discussion the other day with a
couple of therapists who, tongue-in-cheek, wanted to change job title from
“Massage Therapist” to “Muscle Therapist”. 
Not sure that the discussion resolved anything as all parties stuck to
their own biases – mine being that muscles are just living pieces of steak –
how can we think that we are doing anything to change them by massage and
manual therapy?  Instead we are
interacting with the nervous system.

When it comes to treating people who are in chronic pain
then there is a growing awareness that the strength of the therapeutic alliance
between practitioner and therapist is more important than the actual techniques
employed.  In addition, the phenomenon of
Regression to the Mean suggests that therapists are probably overstating their
importance in impacting on client’s chronic pain.

Now the title of this post “Regression to the Mean” sounds
very mathematical with the strong possibility of statistics being
involved.  Whilst it can be explained in
mathematical and statistical language, it can ultimately just be considered common
sense.  Maybe a better title would be
“Get Better Anyway”.

People who are affected by chronic pain are likely to have
fluctuations in how much pain they are experiencing.  Today might be better than yesterday, worse
than yesterday or the same as yesterday. 
Often any changes cannot be attributed to any activity of intervention
that the sufferer has undertaken.  It
just is and there will be bad days and not so bad days.  The pain may change on a daily basis or there
may a few bad/good days in a row before pain levels modify.

Most people will attempt to take action when their pain is
worsening or reaches a particular threshold, eg they will call a massage
therapist on a bad day (or after a couple of bad days).  The therapist will do their magic and lo and
behold the discomfort level may fall over the next few days.

And the therapist takes the credit for the improvement and
it reinforces their bias that the specific treatment they provided was
instrumental in the benefits that the client obtained. 

But the fact is that, very often, the pain levels would have
dropped regardless of what interventions the sufferer took as natural variation
in the client’s condition took hold.

For detailed explanation of this then I would suggest that
you read the article at:

Now this post is not a reason not to book in for a massage
if you are suffering from chronic pain. 
Massage therapists can and do reduce pain and the results can be
relatively quick, relieving and exactly what the client needs.  The change in pain is most likely the result
of the “conversation” between the massage therapist’s touch and the client’s
nervous system.  Calming and providing a
different/interesting stimulus can impact on the brain’s interpretation of the

These benefits though are likely to be the result of touch rather than specific techniques and tools that the therapist has used.  Now it is possible that the massage can impact on the psychosocial component of pain – for example if the client has better quality sleep post massage.  But the reality is that in the days post massage regression to the mean is likely to have more relevance.
