Objective To explore the effect of Kegel exercise combined with biofeedback electric stimulation on the management of postpartum pelvic floor rehabilitation. Methods A total of 200 full-term pregnant women who delivered vaginally in our hospital from May 2018 to April 2019 were randomly divided into two groups: the control group and the observation group, with 100 cases in each group. The control group was only given Kegel exercise method, and the experimental group was given Kegel exercise method combined with biofeedback electrical stimulation. After 2～3 months of intervention, the improvement of pelvic floor muscle function and quality of life of the two groups were compared. Results After intervention, the recovery rate of pelvic floor muscle type I muscle strength in the observation group was 86.0% (86/100), higher than that in the control group (56/100), and the recovery rate of pelvic floor muscle type II muscle strength in the observation group was 83.0% (83/100), higher than that in the control group (54/100). The difference was statistically significant (P<0.05). After the intervention, the patients situations in the experimental group were lower than those in the control group (P<0.05) including abdominal discomfort, urinary incontinence, abnormal urination, abnormal defecation and abnormal vaginal secretion, and the score of sexual quality of life was higher than that in the control group (P<0.05). Conclusion Kegel exercise combined with biofeedback electrical stimulation may promote pelvic floor muscle strength, improve the symptoms of urinary incontinence, pelvic organ prolapse and other pelvic floor abnormalities, and improve the quality of life of patients.

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。

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.

Objective The mechanism about biofeedback is not complete clear. Our aim was to study changes of cardiac function (electrophysiology) during biofeedback with the help of approximate entropy (ApEn), and a potential new mechanism about neurofeedback may be detected. Methods A total of 30 healthy volunteers participated in this study which consisted of the neurofeedback group(n=20) and the control group (n=10). We applied electromyogram neurofeedback as the feedback method, and simultaneously recorded electroencephalogram(EEG) and electrocardiogram(ECG). We applied the nonlinear analysis ApEn assess obtained data. Results In the biofeedback group the average of heart rate was higher than that of control group in the last two sessions. As the biofeedback experiment sessions were progressed, the standard deviation of heart rate gradually reduced and the ApEn of ECG increased with statistic significance in the biofeedback group. Conclusion We found that biofeedback can influence cardiac electrophysiological system and make cardiac systems progress healthily and achieve greater ability of anti-stress.
