<Introduction> Occupational therapists have been faced on such difficulties to treat the motion of range of limited forearm rotation. Most clients were suffered for their activities of daily living (ADLs): such as holding tray, twisting door knob and key, lifting heavy box, and so on. We had invented the orthosis for those clients who needed more stretching exercise to limited forearm rotation mobility. This Forearm Rotation Orthosis was patented by Japan patent office (No.6955256). <Forearm Orthosis Feature> In order to conduct smooth motion of forearm rotation, we figured out two parts of forearm cylinder which are structured inner part to hold whole forearm with wrist joint and outer part to support inner part. Setting elastic twister band over the elbow joint, it is also helping to assist forearm rotation with concept of anatomical muscle conduction.
<Methods> Two clients (1st client: age 51 female, 2nd client: age 11 female) were consulted invented Forearm Rotation Orthosis to expect additional forearm rotation mobility by doctor in charge. The 1st client was diagnosed heterotropic ossification due to left olecranon fracture fixation. The 2nd client was diagnosed radio-ulna synostosis due to malunited forearm fracture. Both clients had similar histories which had severe forearm limited rotation in approximately 6 months. Informed consent was obtained from both clients regarding this presentation. <Result>Supination(active/passive) and pronation(active/passive) were measured for each client. The 1st client had been fitting invented orthosis from 2 weeks post-operation. The range were starting at supination (65°/80°) and pronation(40°/70°). It was completed with supination(80°/90°) and pronation(70°/80°) in 17 weeks. The 2nd client had been fitting from 2 months post-operation. Invented orthosis had started with supination(65°/85°)and pronation(60°/85°), then had completed with supination(80°/90°) in 1 year. Both clients had no sequelae at all.
<Discussion >As a result, invented Forearm Rotation Orthosis had an effect on reproduce forearm rotation mobility with increasing range of motion. Especially in case of clients who had long period with not using forearm rotation, it unconsciously educated the wrong direction such as trick motion. Thus, we recommend to try this invented Forearm Rotation Orthosis in addition to stretching exercise whenever after forearm operation.
