One treatment that I have been receiving in physical therapy recently which I have noticed has helped me a lot has been the Graston technique. It’s a technique that uses blade-like instruments to break up scar tissue and fascial restrictions to help the muscle function normally. Although it has been reported that people can experience minor discomfort during the treatment, I have not experienced any. What I have experienced, however, is improved ROM in the knee along with increased strength during exercise.
