How to test for subscapularis tendonitis?

The subscapularis muscle is the biggest rotator cuff muscle and is the key to shoulder strength when weight lifting and internal rotation of the arm. Motions such as lifting the arm overhead are most likely to cause pain. Weight lifters, tennis players, and swimmers are more likely to injure this muscle. Acute tears can occur with a single instance of heavy weight lifting. The lift-off test is performed by asking the patient to put their hand behind their back, palm facing away from the body with thumb pointing up, and then lift it away from the back against resistance. Pain and weakness suggest tendonitis and/or tendon tear.
