- The shoulder is made up of three bones that are connected and stabilized by the rotator cuff. Impingement occurs when the arm is raised above shoulder level and the space between one of the bones and cuff narrows causing rubbing within the point. This "impingement" causes pain and irritation. The main symptom for this condition is the pain from the rubbing.
In physical therapy, range of motion will be focused on as a mechanism to reduce the pain and then the goal will be to strengthen the muscles of the rotator cuff.
