pronation
Quick Summary
Pronation is a rotational movement of the forearm and hand, or the foot. In the forearm, pronation occurs when the palm faces backward or downward. This is achieved by the radius and ulna bones crossing each other. In the foot, pronation involves the inward and downward rotation of the midtarsal bones, which can cause the foot to land on its inner edge during walking. The muscles responsible for pronation in the forearm include the pronator quadratus and pronator teres. There is no comparable movement in the leg to the supination and pronation seen in the arm.123
