dc.description.abstractIn small quadrupeds, internal rotation of the humerus and subsequent supination of the forearm are related to locomotion. Internal humeral rotation is correlated with backward movement of the limb during the stance phase. In the opossum, an early predecessor of primates including man, the internal humeral rotation imposes supination on the forearm during the propulsion stroke. In planar movement of the human hand, e.g. a vertical shift overa flat surface,rotation of the humerus is involved. Forward movement implies an internal rotation, backward movement an external rotation. This external rotation imposes some degree of pronation on the lower arm. As a consequence, excessive repetitive forward-backward shifting of the hand (palm downwards) may result in overactivity of the m.pronator teres, and may eventually lead to pathological conditions like repetitive strain injuries (RSI). Such injuries do often occur in PC-workers, as a consequence of their handling of the computer mouse. The present study focused on the anatomical features of the pronator teres muscle investigated in normal human anatomical specimens by means of dissection, morphometry and roentgenphotogrammetry. Humeral (superficial) and ulnar (deep) heads of m. pronator teres fuse, their common tendon inserting on the tuberositas pronatoria of the radius. Vectorial decomposition of forces indicates that the effective contribution of m. pronator teres to pronation of the forearm may be considered as somewhat limited. M. pronator teres' vector of elbow flexion appears to be about 4 x its pronating vector. Further reduction of the pronating muscle activities in shifting of the hand (palm downwards) when handling the PC-mouse, may be attained by preventing the lower arm to use its full range of pronation. Using lightly slanted computer mice thus prevents the hand to display fully palm-downwards positions. Consequently, decreased pronator teres activities in PC-workers using such mice were demonstrated (Chen & Leung, 2007)..-
