Supination: Outward rotation of the forearm occurring the radioulnar joint which results in the palms facing forwards or upwards. This is the anatomical position of the arms and hands. The radius and ulna bones of the forearm are arranged so that that, at their distal (elbow) end, the end of the radius is able to cross over the end of the ulna. This crossing results in the rotation of the forearm to a position of pronation. Supination is the uncrossed position of the radius where the bones lie parallel to each other, returning the palmar surface of the hand to the forward or "supine" position. A supinated grip in strength training is one where the palms are facing up or forward, away from the body.
Supination and Pronation of the Forearm and Hand
Supination is also used to describe an excessive outward rolling motion the foot and ankle during a walking or running stride. This motion can place extra stress on the foot. Supination is more common in those with flat feet and can lead to foot aches and pain, such as Iliotibial Band Syndrome,[Plantar Fasciitis, Shin Splints and Knee Pain. Sometimes called under-pronation (or high arches). See Anatomy and Human Movement: Structure and Function (Physiotherapy Essentials) by Nigel Palastanga, et al.
