上肢残肢的常规康复治疗和肌电信号反馈训练

The prosthetic rehabilitation and training of myoelectric signal for upper limb stumps

目的探讨上肢截肢患者的常规康复治疗、残肢肌电信号训练程序以及装配肌电假肢的方法，并观察其效果。方法对20例截肢患者（22个残肢）进行常规康复治疗，包括肌力训练、肌肉收缩控制训练和残肢并发症的处理。采用德国Otto Bock公司提供的肌电信号检测和训练软件系统进行肌电信号训练（分为基础肌电信号训练和视觉反馈训练两个阶段），并装配肌电假肢。观察患者的治疗效果。结果20例截肢患者22个残肢肌肉无明显萎缩，肌力好，关节活动范围无明显受限，患者能较好地控制残肢肌肉收缩。装配肌电假肢20例（20个），所有残肢均能有意识地引出肌电信号，控制假肢的手指打开、闭合以及腕关节的旋转或肘关节的屈伸。结论残肢常规康复治疗和肌电信号训练对装配肌电假肢，实现有意识地控制假肢功能极为重要。

Objective To evaluate the effect of prosthetic rehabilitation and analyze the exercise training program with myoelectric signal for upper limb stumps. Methods Twenty cases 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 myoelectric signal of upper limb stumps were detected and the stumps were trained with electronic bio- feedback software system, including basic signal of biofeedback training and visual biofeedback training. Then the myoeleetric prostheses were assembled. Results After prosthetic rehabilitation and myoeleetrie signal training, there was 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 myoelectric prostheses were assembled. Conclusion The prosthetic rehabilitation and myoelectric signal training of limb stump is important for assembling myoelectric prosthesis.
