摘要： 脑卒中患者异常步态的形成主要与患侧下肢肌肉不同程度的力量下降和张力增高有关，而表面肌电图(sEMG)能客观定量反映神经肌肉的功能状态，对脑卒中患者的异常步态分析具有较高的应用价值。本文主要介绍步行的解剖学基础及sEMG特征、脑卒中患者的异常步态表现以及基于sEMG的脑卒中后异常步态分析，并重点从sEMG应用于分析异常步态相关肌肉活动的时序模式、激活特点和异常步态模式等方面阐述sEMG在脑卒中患者异常步态分析中的研究进展情况。

Abstract: The abnormal gait after stroke was mainly related to the decreasing strength with increasing tension of paretic lower limb muscles. Surface electromyography (sEMG) can respond to the neuromuscular function, that is valuable for abnormal gait analysis for stroke patients. This paper mainly introduced the anatomical basis with sEMG features of walking, the performance of abnormal gait and abnormal gait analysis based on sEMG. It focused on the advances of sEMG in the analysis of temporal patterns and activating characteristics of muscles associated with abnormal gait, as well as abnormal gait pattern.
