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. 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...
