That describes exactly the neurological theories and approach of the physical therapy office I go to. The idea is that after traumatic events, the brain can recalibrate its pain registration threshold. Through the process of pushing to the edge of that boundary (and just barely beyond), over time it teaches your brain to reset back to a normal level. I have been to many physical therapists and this was very unique and compelling for me, and several months in I am on a good path.
