Fracture of distal radius bone, which is vicinity of a wrist joint angle, is major disease for elderly people. After the treatment, the associated part must be fixed for a long time. As a result, soft tissues such as muscle, skin, ligaments and like around the affected part often become rigid. Such a case is referred to as contracture in which movable range of the joint is restricted. Thus, effective rehabilitation for the contracture of the wrist joint angle is required. Traction of the wrist during flexing and extending the wrist joint is proposed as efficient rehabilitation procedure. Previously, we fabricated a rehabilitation equipment capable of such rehabilitation, and dynamic motion of carpals in the wrist was observed by radiography. From the obtained results, the rehabilitation effect was evaluated with contribution ratio of the joint angles. This study compares the rehabilitation effect of the fabricated equipment with that of an occupation therapist and confirmed its availability. Furthermore, it is clarified that the evaluation of joint angle displacements is important to investigate the effect of the rehabilitation procedure.
