在这项工作中，我们研究了功能性电刺激（FES）对中风患者跌落足的治疗效果，分析了胫骨前肌（TA）的表面肌电图（sEMG）。10名受试者在临床环境中接受FES治疗结合常规卒中康复计划，每周5天，每天60分钟，为期12周。基线和治疗后测量TA肌肌电信号的时间和频谱参数。评估结果报告了平均绝对值（MAV），均方根（RMS）的增加，并改善了肌电能谱的振幅和中位数频率（MF），以监测最大自主收缩（MVC）期间胫骨前肌的改善。我们的结论是，与FES系统结合常规康复计划行走可以提高中风幸存者的肌肉力量。
In this work we have examined the effect of functional electrical stimulation (FES) in the management of drop foot in stroke subjects with surface electromyographic (sEMG) analysis from the tibialis anterior (TA) muscle. Ten subjects were assigned to FES therapy combined with conventional stroke rehabilitation program 5 days a week, 60 min a day, for 12-weeks in clinical settings. Baseline and post-treatment measurements were made for temporal and spectral parameters of EMG signals of TA muscle. The evaluation results reported an increase in mean-absolute-value (MAV), root-mean-square (RMS) and also improved the amplitude and median frequency (MF) of the sEMG power spectrum in monitoring the improvement of the tibialis anterior muscle during maximum voluntary contractions (MVC). We conclude that walking with FES system combined with a conventional rehabilitation program improves the muscle strength in stroke survivors.
