Elbow and Forearm Mechanics

For supination limitations, loading or positioning the arm in some supination may help restore wrist extension by changing elbow and forearm orientation. Pronation is associated with wrist flexion and ulnar deviation, while supination is associated with wrist extension and radial deviation. Shoulder, elbow, and forearm mobility influence how the wrist is oriented during loaded tasks. Limited supination may affect wrist extension availability. Exercise selection should train people near positions they cannot access while still allowing them to practice the movement.
