Sit with your elbow bent at a right angle and tucked against your side, with your thumb pointing up. Slowly turn your palm up towards the ceiling, then slowly turn it down towards the floor. Keep your elbow still against your side. One turn up and one turn down counts as one.
If an exercise hurts more than you expect, stop and contact your clinician.
