摘要
肌肉疲劳通常是指肌肉运动系统最大作功能力或者最大收缩能力的暂时下降,sEMG信号可以在一定程度上反映肌肉收缩功能的变化,其检测具有非损伤性、实际性、多靶点测量等优点。多年来,应用sEMG信号分析评价肌肉疲劳的应用性研究主要集中在线性的时、频分析两个领域,主要的研究包括肌肉活动和肌肉疲劳的sEMG信号维数、复杂度、熵变化规律和特点等,认为肌肉疲劳至少存在两类作用机制,即外周机制和中枢机制。
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. The test has the characters of non-damage and practicably. In many years, the application of signal of sEMS on evaluation of muscular fatigue mainly focus on two aspects of linear time and frequency. It includes the signal of sEMS of muscular activity, fatigue. Muscular fatigue may exist two kinds of function mechanism, the peripheral and central mechanism.
