Dart-throwing motion has attracted attention as a functional and novel movement. To date, wrist joint splints regarding traction function and dart-throwing motion with a single splint have been hardly investigated. Therefore, a new artificial muscle-type dynamic traction splint incorporating this novel motion pattern was devised, aiming to investigate the therapeutic use of the dynamic traction splint by artificial muscle in patients with wrist joint contractures. Four hands of three patients diagnosed with wrist joint contractures were assessed. The average splint usage period was 5 weeks. The wrist joint range of motion and grip strength were evaluated initially and after 5 weeks. The wrist joint range of motion was evaluated over a 6-week period. The splints were required to be worn four times. The traction force was initiated at 500 kPa and was appropriately altered based on patient symptoms. The mean (±standard deviation) palmar flexion angle was 21.3° (±5.4) initially and 43.8° (±9.7) at 5 weeks; the improvement in the angle was 22.5°. The mean dorsal flexion angle was 16.3° (±4.4) initially and 45.0° (±6.9) at 5 weeks; the improvement in the angle was 28.7°. The grip strength improved from 15.7% of the healthy side at the start to 72.5% after 5 weeks. These results indicated that therapeutic outcomes with the dynamic traction splint by artificial muscle were almost the same as those with rehabilitation for both dorsiflexion and palmar flexion, suggesting that dynamic traction splint by artificial muscle may be an effective splint for the management of wrist joint contractures. |
