For those of you manual therapists out there who beleive that you are truly changing the amount of motion at a vertebral level or other joint (on a long term basis due to non-muscular effects) .....here is a question.....
Since you can apparently take a joint that is hypomobile and normalize the motion......
What happens to all of your cont. ed classmates and study partners as you take classes, prepare for certification and practice on each other? If you truly were having a long term effect on the range of motion available, then wouldn't all of the repeated manipulations and mobilizations make most of your "normal" partners hypermobile and lead to problems?
I should be off studying biostats but Iv'e had this question on hand for a while.
Respectfully,
mcap

I believe that most of the effects of mobilization and manipulation are neuromuscular but I do feel that my joint mobility has been permanently affected by taking post-grad courses. My neck creeks, my shoulders pop (all technical terms). I think most of it is from people learning who were using innapropriate force, amplitude, direction, or technique. I remember practicing with one person who cracked my neck. It felt like it was the actual disk that popped. The amplitude felt like she took a running start at it. I do tend to have loose joints.
Will it become problematic? I don't know but I have a subluxing SC joint that has gone from only subluxing at full flexion to subluxing with my arm at my side and from not feeling it at all to feeling distinctly uncomfortable.
There was a recent in vitro study showing stiffness changes in the shoulder capsule after mobilization. So although I feel that most of the effects are neuromuscular I do believe that repeated mobilization and manipulation can have a long lasting effect.
I finished my final stats project on Monday.

mcap,
The more I read and practice manual and manipulative therapy, the more I believe that a lot of what we do can not be explained purely by biomechanics. Biomechanics may aid in deciding what we should do, which way to push, but more understanding of the neuromuscular effects, and the effects on the CNS is warranted. Until then, we will only have part of the picture, not the entire picture.

Hi Mcap,
Like Doug mentioned: my neck creeks etc.after doing the manual therapy course. I think it's hypermobile.
Restoring ROM doesn't necessarily mean it's only bio-mechanical, nor is it just neuromuscular. Henry already mentioned: "we will only have part of the picture, not the entire picture."
I do think that the location of the manipulated area is quit important: I think the (upper) cervical area responds more or less with a neuromuscular reflex, not just in the upper cervical area, but in the whole body as well. Whereas a manipulation in the lumbar region, might be more biomechanical.
BTW, does a manipulation always mean a high velocity thrust??(in the Netherlands it usually does)
Cheers
Ben
PS: Henry, nice to see you here!
