Shoulder pain accounts for 33.2% of physician office visits for musculoskeletal pain in the United States. The prevalence of shoulder pain is 7% to 27% for adults and is increasing for women and older individuals. The most frequent cause of shoulder pain is subacromial impingement syndrome (SIS), which includes a number of pathological entities: rotator cuff syndrome, tendonitis and bursitis in the shoulder. SIS occurs when the soft tissues of the glenohumeral joint between the coracoacromial arch and the humeral tuberosity are compressed, disturbing the normal slidingmechanism when elevating the arm. Current approaches to treat SIS include conservative management comprising rest (but not immobilization), ice packs, physiotherapy, or NSAIDS, or any combination of these approaches. In some cases, surgical treatment may be considered an option.
