摘要
表面肌电信号是从肌肉表面通过电极引导、记录下来的神经肌肉系统活动时的一维时间序列信号 ,其变化与参与活动的运动单位数量、运动单位活动模式和代谢状态等因素有关 ,能够实时地、准确地和在非损伤状态下反映肌肉活动状态和功能状态。本文拟就 s EMG信号分析及其应用研究进展进行系统回顾。
sEMG signal is a one dimensional time series signal of neuromuscular system recorded from skin surface. Its time and frequency domain characters are related to the number and activity patterns of MU and the state of muscle metabolism, and the sEMG measurement can reflect the states of muscle activity and muscle function accurately and non-invasively. The sEMG signal analysis and application are reviewed in this paper.
