Supination, Orthopedia Wiki

Supination, opposite of pronation, is the position of a body part or the entire body being ventral side up. In the case of the foot, the plantar surface is the ventral surface.  The body is in a supine position when it is ventral side up. This would be laying down on the back, stomach up. Supination in the foot is a triplanar position, caused by the motions of inversion, adduction, and plantarflexion. This could lead to a bow-legged stance.  The hand is in a supine position when it is palm up.
