During the closed-chain strengthening portion, participants will be asked to perform 6 exercises focusing on the shoulder girdle. Closed-chain strengthening will be performed with the shoulder moving over a fixed hand. Resistance will be provided by body weight against gravity. To off-load and progress the amount of body-weight resistance, elastic bands will be used to support body weight. The elastic bands will be attached to support frame used for the exercises. As the patient improves, less elastic band support will be provided to allow increased resistance via the patient's body weight. The criteria for determining if the resistance is too high or the exercise is too difficult will be based on 2 criteria: 1.) after the exercise is completed, the participant rates their shoulder pain > 2/10 increase as compared to baseline pain taken at the start of that day's treatment session, on the numeric pain rating scale, and 2.) BORG scale > 3 (moderate difficulty) and an inability of the participant to maintain proper exercise form and full range of motion. If these criteria are met then the physical therapist will modify the exercise so the subject can perform similar movement pattern without pain. The goal will be for the participant to perform 2 sets of 20 repetitions, of each exercise. When the participant is able to perform 24 repetitions with the given load, over 2 successive treatment sessions, then the resistance will be increased.
