Active assisted shoulder internal and external rotation in neutral (using your own arm) is a gentle mobility exercise that targets the rotator cuff muscles—primarily the subscapularis (for internal rotation) and infraspinatus and teres minor (for external rotation). This exercise is typically performed with the elbow resting by the side of the body, keeping the shoulder in a neutral position. It’s often prescribed during early stages of shoulder rehabilitation to improve rotational range without placing excessive stress on the joint, especially following rotator cuff injuries, shoulder surgeries, or adhesive capsulitis.
