There is some efficacy, especially relating to musculoskeletal issues. Whenever I have a sore elbow, or neck pain, I make a beeline for my colleagues in our OMT dept, Drs ED or KC. It amazing how they fix me.
Yet a good chunk OMT remains in the realm of unproven claims, and probably is more based upon observer bias. There is a lot of subjectivity and my students complain bitterly at exam time how Dr A tests one technique one way, and Dr B tests the same technique a different way.
Some things that are overtly preposterous
may be efficacious, but require a more realistic explanation (like craniosacral therapy...those bones do NOT move.) Foundations like Chapman's points are unproven.
A lot of the techniques for a particular ailment are very testable as hypotheses. I am dumbfounded that many of my DO colleagues are unwilling to test their cherished notions. The nature of Medicine is that if something doesn't work, you toss i tout and try something else.
The big picture that DOs are more holistic that MDs is insulting to our MD colleagues. If one is going to make a claim, it needs to be backed up with data. the claim might have been true 100+ years ago when there were very few things that were effective as treatments.
There might be some patient satisfaction surveys out there somewhere, but I'd be happier if we could see them.
I tell my more skeptical students "just suspend your disbelief and see if you can learn something useful". I believe that the palpatory skills and the comfort in touching other human beings does yield positive effects in the doctor/patient relationship.
The DO stigma is less about OMT now
and more about poor clinical training in years 3 and 4.
I'm sorry if this is a dumb or offensive question, I know very little, but I sincerely want to know, how legit is the OMM stuff taught in DO schools? I know it's said that in the end both MDs and DOs are pretty much the same, but I'm genuinely wondering how much impact OMM has. I've always been interested in natural medicine and the like, but as we all know homeopathy is not taken very seriously. Still, the fact that DO schools offer something other than traditional medicine is intriguing to me. From what I've seen, medicines can be as harmful as they are helpful.
So is OMM just a tacked-on thing that sounds good, or is it a legit methodology that is useful?
