CONTRIBUTIONS OF TACTILE, MUSCULO-TENDINOUS AND JOINT MECHANISMS TO POSITION SENSE IN HUMAN SHOULDER

Abstract

The ef-fective participation of tactile and musculo-tendinous receptors was a-bolished separately and the resultant effect upon the accuracy of shoulder position sense was measured by means of a pointing type test previously described. Tactile receptors were interfered with by applying an adhesive tape net to the skin of the shoulder and musculo-tendinous receptors were affected by a 1 k weight held in the hand. It was found that the principal contribution to position sense accuracy of the shoulder is made by articular receptors, although the tactile and musculo-tendinous receptors each make a small but significant and independent contribution.
