Ask a PT Response: "I would recommend that you speak with the PT that was working with your son to determine if there are additional exercises that he could perform to help minimize his condition. Another thing I would have the PT look at would be his throwing and swinging mechanics. I often find with the athletes which I work with that poor mechanics will often contribute to an injury. Often times, the athlete would compensate mechanics as a result of weakness, instability or tightness at another part of the body thus resulting in added stresses and or injury. I hope this helps and thanks for using CyberPT."
