What does supination involve concerning the hand or foot?

Supination refers to the motion of turning the palm of the hand or the sole of the foot upward. When discussing the hand, supination involves rotating the forearm so that the palm faces forward or upward, which is particularly relevant in activities like receiving an object. In the context of the foot, supination describes the movement that results in the outer edge of the foot lifting and the weight shifting from the inner side, which can impact walking and running mechanics. Understanding supination is essential in various fields, including anatomy, physical therapy, and sports science, as it plays a crucial role in maintaining balance and coordinating movements.
