一、引言近年来,在康复医学上逐渐出现各种电子装置帮助残疾人补偿或代替部份功能。通常,外伤性截瘫是由于脊柱骨折或椎间脱位,损伤脊髓或马尾神经造成大脑发出“走路”指令无法传递到腿部肌肉,以至于无法指挥腿部的动作。计算机化的截瘫助行系统是通过各种传感器把大脑发出的“走路”指令经计算机识别后,给肌肉或支配肌肉运动的神经施加一串电脉冲,使肌肉产生收缩动作,从而恢 I. INTRODUCTION In recent years, various kinds of electronic devices have been gradually emerging in rehabilitation medicine to help people with disabilities to compensate or replace some functions. Typically, traumatic paraplegia is due to spinal fractures or intervertebral dislocation, damage to the spinal cord or cauda equina causing the brain to “walk” command can not be transmitted to the leg muscles, so that the leg can not command the action. Computerized paraplegic system is through a variety of sensors to the brain issued a “walk” command by the computer to identify, to the muscle or dominate the muscles of the nerve to impose a string of electrical pulses, the muscles produce contraction action, which restore
