摘要
目的:观察功能性电刺激(FES)对脑卒中患者上肢体感诱发电位(SEP)及运动诱发电位(MEP)的影响。方法:符合入选标准的13例脑卒中患者分为FES组(9例)和FES安慰刺激组(4例)。患侧上肢腕背伸拇外展肌群接受FES治疗(30min)或安慰刺激(30min),FES治疗频率30Hz,脉宽200μs,强度为患者最大耐受量;治疗前后分别接受SEP及MEP检测,记录SEP检测中N9及N20潜伏期和波幅,MEP检测中正中神经的肘部刺激点,臂丛区刺激点,C7刺激点及皮质刺激点潜伏期和波幅;比较同一测试时间点MEP重复检测的信度,并对组内同侧治疗前后,组间治疗前后SEP、MEP变化率进行比较。结果:2组患者MEP值各部位5次测量值的相关系数值均在0.8317—1.0000之间;2组患者患侧皮质MEP均未引出;FES组治疗后患侧SEP及MEP潜伏期均有缩短,波幅明显增高(P<0.05);FES组健侧和安慰刺激组双侧刺激后SEP及MEP变化不明显;刺激前后变化率比较差异有显著性意义(P<0.05)。结论:脑卒中患者患侧上肢FES后SEP及MEP潜伏期有缩短,波幅有增高。
