Answer:

Structure and Function of the Elbow and Forearm Complex

Kinematics

Supination occurs in many functional activities that require the palm to be turned up, such as feeding, washing the face, or holding a bowl of soup. Pronation, in contrast, is involved with activities such as grabbing an object from a table or pushing up from a chair, which require the palm to be turned down.

Supination and pronation occur as the radius rotates around an axis of rotation that travels from the radial head to the ulnar head (see Fig. 5.12). The 0-degree or neutral position of the forearm is the thumb-up position (Fig. 5.14). From this position, 85 degrees of supination and 75 degrees of pronation normally occur. People who lack full range of motion of these movements often compensate by internally or externally rotating the shoulder, so clinicians must be aware of this possible substitution when testing the range of motion of the forearm
