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.
在这项研究中，我们通过对胫前肌进行表面肌电图（sEMG）分析，研究了功能性电刺激（FES）对中风患者足下垂管理的效果。十名受试者被分配到FES治疗组，在临床环境中，每周5天，每天60分钟，与传统的中风康复计划相结合，为期12周。对胫前肌肌电信号的时间和频谱参数进行了基线和治疗后测量。评估结果显示，在最大自主收缩（MVC）期间监测胫前肌改善情况时，平均绝对值（MAV）、均方根（RMS）增加，表面肌电图功率谱的幅度和中位频率（MF）也有所改善。我们得出结论，FES系统与传统康复计划相结合的步行方式可提高中风幸存者的肌肉力量。
