What Does Supination of the Foot Mean?
Supination of the foot is when the foot rolls outwardly. This motion is normal during walking and running, particularly as the foot is pushing off from the ground. Like any motion, this places stress on the joint and muscles. Over repetition or incorrect repetition of supination can cause musculoskeletal injuries.
In the foot correct supination is needed for the person’s gait to be correct whether walking, running or jogging. If the supination is such that too much pressure or weight is placed on the outer portion of the foot, several medical issues can arise. In the work area those without correct supination may have difficulties in accessing machinery where they have to have full range of motion with their forearms. If the worker is one who continually walks long distances, especially over a hard surface like a concrete floor, stress fractures can occur.
Supination is also known as underpronation.
