ABSTRACT
Objective To evaluate the effect of prosthetic rehabilitation and analyze the exercise training program with myoelectric signal for upper limb stumps.Methods Twenty canes with 22 upper limb stumps were treated with exercise for strength training,muscle contraction and control training and the complication of stump were managed.The myoelectrlc signal of upper limb stumps were detected and the stumps were trained with electronic biofeedback software system,including basic signal of biofeedback training and visual biofeedback training.Then the myoelectric prostheses were assembled.Results After prosthetic rehabilitation and myoelectfic signal training,there Wan no significant atrophy of muscle of stumps,muscle strength and range of motion of these twenty limb stumps increased.The amputees could control muscle contraction and grasp,pinch,wrist rotation,elbow extension or flexion consciously.Twenty myoelectrie prostheses were assembled.Conclusion The prosthetic rehabilitation and myoelectric signal training of limb stump is important for assembling myoelectric prosthesis.
