title: Tendon excursion of wrist movers.
abstract: In mechanical terms, the wrist joint is moved by a system of effective pulleys and levers influenced by the anatomic structures present at the wrist. Assuming that the tendon excursion in a cadaver would reflect the excursion of the corresponding tendon in a live hand moving the wrist through the same arc of motion, this study measures the excursions of the wrist tendons during flexion-extension motion and radioulnar deviation in different positions of forearm rotation and relates tendon function to anatomic configuration. Two separate experiments were performed to measure the tendon excursion, in one of which the data were collected manually and in the other a system of computer-aided data collection was used.
