| 摘 要： | 表面肌电信号是一种使用表面电极来探索和记录肌肉表面电活动的技术。肌电信号在生物力学领域中主要被用来作为肌肉开始激活的指标,同时作为肌肉收缩产生力量以及肌肉内部产生疲劳的指标等。表面肌电信号作为研究肌肉的一种方法,告诉我们肌肉是否被激活、激活的程度大小和疲劳时激活的程度等。旨在着重讨论生物力学领域中的一些特定的表面肌电信号分析方面中的比较类型分析和频率疲劳分析问题。

| Abstract: | Surface electromyography(SEMG) is a technique for detecting and recording the electrical activity of the muscles using surface electrodes.The EMG signal is used in biomechanics mainly as an indicator of the initiation of muscle activation,as an indicator of the force produced by a contracting muscle,and as an index of the fatigue occurring within a muscle.EMG,used as a method of investigation,can tell us if the muscle is active or not,if the muscle is more or less active,when it is on or off,how much active is it,and finally,if it fatigues.The purpose of this article is to discuss some specific EMG signal analysis aspects with emphasis on comparison type analysis and frequency fatigue analysis in biomechanics. |
