I can vouch for it having been useful for me, even though on at least one occasion I went in as a grump in a lot of pain and came out as a grump in a bit of pain. I've had several different courses of it, for different injuries, and in 2002 the fact that they got me from "barely able to walk without wincing" to "trail riding and hiking up a mountain top" in 4 months was seriously impressive. They stopped my pelvis from completely falling apart in 2003 - physio can be preventative or "problem management" as well as curing - but the post-surgery rehab in 2010 was less helpful (partly because the internal stitches had burst and we didn't realise for a while how badly that was affecting me). Physio on a damaged elbow was amazing - learned all sorts of tricks to get it moving without pain, which work on other bits of me. Am hoping the next course does similar for the healing bit of my shoulder, although there's bugger all they can do for the disintegrating part. For that, I'm just hoping for tips on not making it worse.
