摘要： 目的探讨肌电生物反馈对正常人脑血流动力学的影响及其变化规律。方法总数30人的健康正常受试者纳入研究,按照表格法随机分为生物反馈实验组和对照组。其中生物反馈组20人,对照组10人。该试验采用肌电生物反馈作为反馈方法,记录两组试验前后双侧大脑前动脉、大脑中动脉和大脑后动脉的平均血流速度和脉动指数。每次生物反馈试验后间隔3天,作为一个生物反馈阶段,总共进行7个阶段。结果生物反馈组大脑中动脉的平均血流速度在试验前、后高于对照组(P<0.05),而其脉动指数则低于对照组(P<0.05)。生物反馈组在试验前、后大脑中动脉的平均血流速度随着生物反馈次数的增加而增快(P<0.05),而脉动指数则随之而降低(P<0.05)。结论肌电生物反馈能够增加正常人大脑中动脉的平均血流速度和降低其脉动指数,且随着生物反馈次数的增加而呈现累积效应。

Abstract: Objective To discuss the effect of electromyographic biofeedback on cerebral hemodynamics in health people. Methods A total of 30 healthy volunteers were enrolled in this study, and randomly divided into biofeedback group (n=20) and control group (n=10). The biofeedback group had been done with electromyographic biofeedback for seven times with 3 days intervals after each test. The data including the mean velocity (Vm) and pulse index (PI) of anterior cerebral artery, middle cerebral artery (MCA) and posterior cerebral artery were collected bilaterally before and after the test using transcranial Doppler in the two groups. Results The values of Vm (P<0.05) were higher and PI (P<0.05) were lower in biofeedback group than those in control group before and after the test. The values of Vm (P<0.05) increased and PI (P<0.05) decreased gradually in biofeedback group from 1st to 7th tests. Conclusion The electromyographic biofeedback can induce to the increasing of velocity of cerebral blood flow and decreasing of PI in MCA, and the additive effect was observed during the 7 tests in biofeedback group.
