摘　　要：目的提出一种面向下肢截肢患者,可实现等长和等张训练的下肢残肢康复训练识别的新方法。方法使用表面肌电传感器采集并分析10例小腿截肢者在康复训练中股直肌的表面肌电信号,对下肢康复训练模式进行识别。结果利用肌电信号的平均绝对值、方差和功率谱比值进行特征值的提取,可以用肌电信号的特征值作为输出建立表面肌电信号与下肢残肢康复动作之间的关系。结论该方法利用肌电信号可以完成对下肢残肢康复动作的识别,可作为进一步探索下肢残肢康复训练系统的训练方案的依据。Objective To provide a new method for recognizing isotonic or isometric exercise in the rehabilitation of lower residual limbs for the patients after amputation. Methods The signs of surface electromyography （sEMG） of leg quadriceps of 10 amputees in rehabilitation were collected with EMG Sensor and analyzed. Results The absolute magnitude average （MAV）, variance （VAR） and power spectrum coefficient of sEMG can be used as the character value to establish the relation of the sEMG sign and lower limbs motor of rehabilitation. Conclusion A method recognizing the pattern of lower limbs motor in rehabilitation has been advanced, which may be used in further study for the systems controlling lower limbs in rehabilitation of residual limb.
