As a Physio I can do the exact same treatment as a chiro or an osteo, just as it works in reverse, and we all work from the same evidence base, so I'm not really sure how a Physio treating is much different to another rehab professional? Bar the philosophy on which its based.
Take a PT/Chiro/Osteo of 20 years experience each, I can say with pretty much certainty they will all use the same methodology just in a slightly different manner.
