The most common cause of shoulder pain in the older population is due to soft tissue injuries 1. These include frozen shoulder, subacromial impingement, rotator cuff tendinopathy or rupture, and acromioclavicular joint osteoarthritis. The pain may also be caused by glenohumeral osteoarthritis or rheumatoid arthritis, due to the degeneration and, or destruction of the joint. In addition, pain may be referred, from in particular, the cervical spine.
