Movement Patterns at Joints *Click images to enlarge*
Pronation occurs at the elbow and involves internal (medial) rotation between the radius and humerus, as well as the crossing of the radius and the ulna. It normally occurs when the palm of the hand is moved from facing upwards to facing downwards.
Supination is the opposite of pronation and once again takes place at the elbow joint. This movement is external (lateral) rotation between the radius and the humerus, and occurs when the radius and ulna are parallel. When the palm of the hand is turned so that it faces upwards, supination has taken place.
