Before
getting this week’s article started I have a couple announcements
1) I’m currently halfway through Charlie
Weingroff’s DVD T=R3 and am loving it so far. I hope to do a review of it for
the blog.
2) As next Monday is a long weekend I will not
be posting a new article that week. Tune in in 2 weeks for my next piece -3
applications of Interval Training for Health.
Now getting to the point of my story…
I
understand that I’ll get a ton of flack for saying this but it needs to be said
anyways – manual therapy is not this complex, high skilled task that many
therapists like to think it is. It’s not so simple that just anyone can do it,
it requires you to apply force safely & to know contraindications, but it
isn’t this fancy skill that requires tens of thousands of dollars in training
to get results with.
It’s
important for me to write about this as I see many new therapists that are
underconfident and feel like their manual therapy skills aren’t up to par with
their colleagues. Plus many therapists, myself included, feel (or have felt) very
frustrated when they can’t “find” these pseudobiomechanical faults that other,
more experienced therapists can.
In
this article I will go over why manual therapy is not the high skill activity
that it’s portrayed to be and how to simplify it …..
Disclaimer: this isn’t going to be a debate
about whether or not to use manual therapy. I see enough bickering about it on
Facebook and quite frankly I have better things to do with my time than get
into an endless debate on the topic.
Disclaimer 2: to keep this article short &
not bogged down in references this is not a systematic review by any stretch.
With that out of the way – here is why and how
manual therapy should be simplified.
Part 1: Assessment
In spinal/SI joint pain cases many therapists
will assess each spinal segment to determine which ones are hyper or
hypomobile. However – these assessments are shown to be unreliable1–4..
“Well you just haven’t developed
the magic hands yet”
That’s the most common argument I see when this
evidence gets presented. However, these assessments are unreliable even amongst
experienced therapists – debunking the skill argument.
Realistically – vertebral segments move a few
degrees each and the SI joint only moves a maximum of 4-8 mm.
In SI joint pain therapists sometimes try to
palpate pelvic position to detect “upslips,” “downslips,” and “rotated
innominates.” These positional assessments are also unreliable4,5.
Part 2: Treatment
Back in PT school I always remember my
instructors telling me “you just want to isolate that one segment” and “you
only want to move that segment.” However – research has shown that spinal
manual therapy directed to one segment actually affects multiple segments and
in one study increased ROM at a different segment than the one being mobilized6!!!!!
A small body of research has also questioned
the concave-convex rule of joint arthrokinematics. For instance, in people with
frozen shoulder, a posterior glide was more effective in increasing shoulder
external rotation than an anterior glide7.
Lastly, some studies have compared different
manual therapy techniques for the same condition and shown that they provide
equal effects on pain & disability8,9.
Now before you’re all ready to lynch me…
I’m not saying that manual therapy needs to be
dumped – it just needs to be reconceptualised within a scientific framework. Manual
therapy techniques provide non-specific effects on muscle tension, pain, and
other variables through neurological mechanisms10.
Side note – please read this free open access
paper on the mechanisms of manual therapy if you haven’t https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2775050/.
The best way of approaching manual therapy is
to keep your approach simple. Some research in spinal pain suggests that the
best techniques are the ones you’re most comfortable & confident performing11. So pick a few techniques for each area that
you’re comfortable with, make sure there are no contraindications or
precautions, use a reasonable amount of force and don’t aggressively crank on
the patient (when in doubt gentler is better) and keep it simple.
Anyways if you’ve made it this far and haven’t
clicked out of the article I just want to say thank you and congratulations on
reading and reconceptualising your view of manual therapy in a way that’s in
line with the scientific literature.
Take home points
-
Many
manual therapy assessment tests (e.g. spinal segmental hyper/hypomobility, SI
jt positioning) lack reliability even amongst experienced therapists
-
Spinal
manual therapy affects multiple joints not just the one you are targeting
-
Some
studies have shown different manual therapy techniques produce the same results
for the same condition
-
Manual
therapy has non-specific neurological effects
-
Some
research suggests that the best techniques are the ones you are comfortable
performing
