Pronation

In anatomy, pronation is a rotational movement of the forearm at the radioulnar joint, or of the foot at the subtalar and talocalcaneonavicular joints.

• For the forearm, when standing in the anatomical position, pronation will move the palm of the hand from an anterior-facing position to a posterior-facing position without an associated movement at the shoulder (glenohumeral joint). This corresponds to a counterclockwise twist for the right forearm and a clockwise twist for the left (when viewed superiorly).
• For the foot, pronation will cause the sole of the foot to face more laterally than when standing in the anatomical position. Pronation is the opposite of supination.
