随着康复医学的快速发展,表面肌电图(surfaceelectromyography,sEMG)作为一种肌肉功能评估的无创、实时客观的手段,在康复医学领域的应用越来越多。表面肌电图是利用电极在皮肤表面采集到肌肉活动状态下的肌电信号,通过收集、分析、放大、显示而记录到的类似于噪声的一种一维电压信号。该信号经过不同的分析转换后得出的指标可一定程度上反映肌肉功能的变化情况。其中,表面肌电屈曲-放松(Flexion-
With the rapid development of rehabilitation medicine, surface electromyography (sEMG), as a noninvasive, real-time and objective means of evaluating muscle function, has been used more and more in the field of rehabilitation medicine. Surface EMG is the use of electrodes in the skin surface to collect muscle activity under the EMG signal, collected, analyzed, enlarged, displayed and recorded a noise-like one-dimensional voltage signal. After the signal is transformed by different analysis, the index can reflect the change of muscle function to a certain extent. Among them, the surface EMG buckling - relaxation (Flexion-
