Sit at a table with your forearm resting on it and your hand open. Slowly bend your fingers down into a hook shape. Then close them slowly into a loose fist, as far as is comfortable. Open your hand slowly again. Never force the fingers. Warming your hands in warm water first can ease stiffness.
If an exercise hurts more than you expect, stop and contact your clinician.
