| 摘 要： | 表面肌电信号分析是评价局部肌肉疲劳有效的工具。过去由于受信号处理技术的限制,对肌肉疲劳的评价仅局限于等长、恒力收缩。由于适合于非平稳信号分析的频谱估计技术的发展,使得动态收缩条件下的肌肉疲劳评价得以实现,在工效学、康复医学和运动医学等方面开启了新的应用领域。本文论述了利用表面肌电信号评价肌肉疲劳,特别是在肌肉动态收缩期间评价肌肉疲劳的方法,为进一步探讨肌肉疲劳的发生机制提供理论依据。

| Abstract: | Surface myoelectric signal analysis has proved effective for assessing the electrical manifestations of localized muscle fatigue.In the past,the analysis of muscle fatigue was restricted to isometric,constant force contractions due to the limitation of signal processing technique.The development and recent availability of spectral estimation techniques specifically designed for nonstationary signal analysis have made it possible to extend the employment of muscle fatigue assessment to dynamic contractions,thus opening new application fields such as ergonomics rehabilitation and sports medicine.This paper reviews the current study achievements of using surface myoelectric signals in muscle fatigue assessment,particularly in that during dynamic contractions.The conclusions provide theoretical bases for encouraging further studies on the mechanisms of muscle fatigue. |
