摘　　要：目的:观察功能性电刺激(FES)对健康年轻人运动诱发电位(MEP)的影响。方法:13例健康年轻志愿者参与了研究,其中男9例,女4例;年龄(24.9±3.1)岁。分别接受30minFES和安慰刺激。采用经颅磁刺激仪(TMS)与肌电图仪(EMG)在FES前、后,安慰刺激后分别检测每一对象的MEP,计算潜伏期、波幅和中枢运动传导时间。结果:健康年轻人在FES后MEP值潜伏期缩短,波幅增高,中枢运动传导时间无明显变化;而安慰刺激后MEP的个参数均无明显变化。结论:MEP值可以反映FES后健康年轻人大脑兴奋性的改变趋势。Objective： To observe the effects of functional electrical stimulation （FES） on motor evoked potentials （MEP） of healthy young subjects. Method：Thirteen healthy young volunteers （9 males, 4 females） were recruited into the study, mean age （24.9±3.1） years. Each subject received FES for 30 min each session and placebo FES respectively. Transcranial magnetic stimulator（TMS） and electromyograph（EMG） were used to measure MEP for each subject before and after FES or placebo FES. Latency and amplitude of MEP and the central motor conduction time （CMCT） were examined. Result： The latencies of MEP were shortened and the amplitudes were heightened after FES, the difference was significant; but there was no significant change of CMCT. In placebo group there was no significant change of indexes of MEP. Conclusion： MEP can reflect the trend of changes of healthy people＇s brain excitability after FES.
