摘要: 目的 探讨脑卒中患者下肢前后肌群在步态周期及其各分相中表面肌电(sEMG)信号的变化,以便有针对性地对脑卒中患者进行步态康复训练。 方法 2018年1月至6月,采用Noraxon表面肌电无线采集系统记录20例脑卒中患者和20例健康对照者在自然行走过程中双下肢胫骨前肌(TA)、股直肌(RF)、腓肠肌内侧头(GM)和股二头肌(BF)的sEMG信号。 结果 健康受试者双下肢TA、RF、GM和BF的肌电活动随步态周期呈活动与静止周期性变化、双侧同名肌肉交替活动,而脑卒中患者双下肢相关肌肉肌电活动发生明显改变,且失去规律性。 结论 sEMG能反映脑卒中患者步态相关肌肉受损情况,可用于指导步态康复训练。

Abstract: Objective To explore the changes of surface electromyography (sEMG) signal during gait cycle and its various phases of the lower limbs of stroke patients, to guide targeted gait rehabilitation training for stroke patients. Methods From January to June, 2018, 20 stroke patients and 20 healthy subjects were involved in this study. All the subjects were asked to walk naturally. At the same time, the sEMG signals of bilateral tibialis anterior (TA), rectus femoris (RF), gastrocnemius medial (GM) and biceps femoris (BF) were recorded by Noraxon wireless surface electromyography acquisition system. Results The electromyographic activities of TA, RF, GM and BF of healthy subjects changed with the activity and static periodicity during gait cycle, and the muscles of the same name alternated, and they were disturbed in stroke patients. Conclusion The surface electromyography can reflect the gait-related muscle damage in stroke patients and can be used to guide gait rehabilitation training.
