肌电生物反馈对脑梗死急性期心率变异性的影响

The Effects of Heart Rate Variability of Acute Cerebral Infarction by Electromyographic Biofeedback

为观察肌电生物反馈对脑梗死急性期心率变异性的影响。本研究选取脑梗死患者60例,随机分为对照组28例和实验组32例,两组均进行常规卒中康复治疗,实验组加做肌电生物反馈治疗。分别于入院一周内和治疗2周检测动态心电图。选取同年龄段、排除脑梗死等影响自主神经活性疾病的动态心电图检查的患者60例,做为正常组,收集其动态心电图数据。正常组与脑梗组比较,脑梗组SDNN、LF、HF值均明显低于正常组(p<0.01),LF/HF比值明显高于正常组(p<0.05);脑梗死患者中实验组与对照组比较,治疗前两组SDNN、LF、HF、LF/HF均无显著性差异(p>0.05);治疗后对照组中SDNN、LF、HF高于治疗前,但无显著性差异(p>0.05),LF/HF低于治疗前,但无显著性差异(p>0.05);实验组中SDNN、LF、HF明显高于治疗前(p<0.01),LF/HF明显低于治疗前(p<0.05)。通过相关分析表明脑梗死患者心率变异指标存在异常。研究结果表明肌电生物反馈可以促进脑梗死急性期患者心率变异指标恢复。

To observe the effect of electromyographic biofeedback on heart rate variability of acute cerebral infarction. In this study, 60 patients with acute cerebral infarction were randomly divided into a control group of 28 cases and the experimental group of 32 patients. Both groups were given conventional stroke rehabilitation theraph, and the experimental group were having electromyographic biofeedback additionally. They were detected heart rate variability which was admitted to hospital within one week and two weeks of treatment respectively. We selected 60 patients in the same age and excluded the impact of autonomic nervous system activity of the disease, such as cerebral infarction as the normal group and collected Holter data. The comparison between normal group and cerebral infarction group indicated that SDNN, LF, HF values of the cerebral infarction group were significantly lower than the normal group （p〈0.01）, the ratio of LF and HF was significantly higher than the normal group （p〈0.05）; The comparison between experimental group and the control group in the cerebral infarction patients, before treatment, SDNN, LF, HF values and the ratio of LF and HF were no significant difference （p〉0.05）; After treatme- nt, the SDNN, LF, HF values of the control group were higher than before treatment, but no significant difference （p〉0.05）; The ratio of LF and HF was less than treatment, but no significant difference （p〉0.05）; The SDNN, LF, HF values of the experimental group were significantly higher than before treatment （p 〈0.01）, the ratio of LF and HF was significantly lower than before treatment （t9 〈0.05）. The analysis showed that the HRV index of cerebral infarc- tion patients was abnormal. The results indicated that electromyographic biofeedback can promote the recovery of HRV index of acute cerebral infarction patients.
