功能性电刺激对健康青年受试者体感及运动诱发电位影响的对照研究

Effects of functional electrical stimulation on somatosensory evoked potentials and motor evoked potentialsof healthy young people

目的:观察功能性电刺激(FES)对健康青年体感诱发电位(SEP)及运动诱发电位(MEP)的影响。方法:采用经颅磁刺激仪(TMS)及肌电图仪,分别测量15例健康青年,其中男10例,女5例,平均年龄(22.9±0.7)岁。单次FES前、后检测SEP值及MEP值,其中11例完成两周FES(每天1次,每次30min),并再次接受SEP及MEP检测。结果:健康青年者单次及2周FES后SEP及MEP值的潜伏期缩短,波幅增高,与FES前比较,差异有显著性意义;非FES侧变化不明显。结论:健康青年者FES前后SEP及MEP值均有变化,尤以波幅明显。

Objective： To observe the effects of functional electrical stimulation （FES） on somatosensory evoked potential（SEP） and motor evoked potential （MEP） of healthy young people. Method： Fifteen subjects were measured SEP and MEP with transcranial magnetic stimulator （TMS） before and after the first FES （30min） ;11 of the 15 subjects were given FES （30min） once daily for 2 weeks, and after the FES course SEP and MEP were measured again as the first time, Result： The latencies of SEP and MEP were shortened and the amplitudes were heightened on FES side after one time and two weeks FES course, the changes were significant. There was no significant difference on the no FES side. Conclusion： Both of SEP and MEP changed after FES, and the changes of amplitudes were significant.
