摘要
表面肌电信号的检测是一种无创电检测方法,它的检测分析对临床诊断及康复医学,运动医学等具有重要意义。肌肉疲劳产生过程中,肌电图的振幅和频谱指标均会产生相应变化,肌肉疲劳通常是指肌肉运动系统最大做功能力或最大收缩能力暂时下降。SEMG信号可以在一定程度上反映肌肉收缩功能的变化,在运动性肌肉疲劳研究中将发挥重要作用。
The detection of surface EMG signal is a noninvasive method,which has great importance in clinical diagnosis rehabilitation medicine and sport medicine The amplitude and power spectrum of EMG will change while muscle fatigue will develop.Muscular fatigue refers to temporary decline of maximal power ability or contractive ability for muscle movement system.The signal of SEMG can reflect the change of muscular fatigue at certain extent.Surface EMG will play an important role in studying athletic muscle fatigu...
