摘要
肌电信号是产生肌力的生物电信号来源,反映了神经-肌肉系统在进行随意性和非随意性活动时的生物电变化情况,它与神经肌肉活动密切相关。伴随着肌电信号特征分析方法的日臻完善,蕴含在信号内的神经、肌肉信息,越来越多地被人们所掌握,并被广泛地应用于临床医学、康复医学、体育科学、医学工程学以及基础研究等诸多领域。因而肌电信号具有重要的应用价值和学术价值。现本文主要针对肌电信号的特征分析方法(时域分析、频谱分析、时频分析等方法)以及肌电信号相关领域的应用情况作以综述。
Electromyographic（EMG） signal is the source of bioelectricity-signal for the generation of muscle force.It reflects the changes of the bioelectricity of the nerve-muscle system during the voluntary movement and the non-voluntary movement,and relates to the neuromuscular activity closely.With the analytical methods of the features of EMG signal become more and more perfect,more and more nerve and muscle information which embody in EMG signal are controlled by us,and it is widely used in clinical medicine,rehabilitation medicine,sports science,medical engineering and basic research fields,and so on.So,EMG signal has important values in the application and the academic.This brief review summarizes the analysis approaches（time-domain analysis,frequency spectrum analysis,Joint time-frequency analysis,and so on） and the applications of EMG signal.
