Here is a very interesting series of articles on pain and rehabilitation.
I believe it might help give insight into why some of the rehab protocols we do work.
As well it might help in tuning how you do your rehab/prehab work for your situation.
There are many other good articles on the subject here, but these i found particularly interesting, and help round out some of the ongoing discussions on the forum.
