When I came to PT for the first time I was six weeks post knee surgery. I could barely walk. PTI helped me build my strength. Now I’m back up and, in the process, I learned where I had been compensating. They taught me how to do things correctly so that I would stop compensating. 2.5 months later I am stronger than I was pre-op and I am functioning normally! I didn’t think I would ever get back to normal, but they made it happen!
