This study examined the kinematic differences between a body-powered
prosthesis and a biomechatronics prosthesis as a transradial amputee performed
activities that involve flexion/extension and supination/pronation of the wrist.
METHOD: The subject's wrist movements were calculated and compared as he
completed a wrist range of motion test involving simulated flexion/extension and
supination/pronation. RESULTS: The results revealed that, under the test
conditions, the body-powered prosthesis limits an individual's ability to
complete four different tasks of wrist movement especially when it comes to
complete the supination/pronation movement. Conversely, while using
biomechatronics wrist prosthesis, the user was able to compensate for limited
wrist motion through an ability to achieve a greater range of wrist movement.
CONCLUSIONS: The biomechatronics wrist prosthesis provides a greater degree of
freedom of wrist flexion/extension and supination/pronation movements.
