Workers in many jobs are required to perform the same tasks day after day. As a result of this repetitious work, many employees are developing what is know as Cumulative Trauma Disorders (CTD). There has been much research done on ways to prevent these disorders. Cumulative Trauma Disorders involving the wrist are of special concern. Repetitive motions and awkward positions of the wrist are a major cause of CTD's in the wrist. One such factor dealing with the posture is the angle between the hand and the forearm. In order to help limit the affects of CTD's of the wrist, a system was developed to compare the amount of muscle activity with the angle of wrist deviation. Muscle activity can be related to the amount of stress occurring in the wrist. This system can be used to help evaluate current jobs and proposed techniques for wrist stress.
