目的：本研究旨在对电针治疗急性缺血性脑卒中患者脑电图的频率、波幅进行观察分析，进而从神经电生理方面对其疗效进行评估。方法：90例急性缺血性脑卒中患者随机分为空白组，普通针刺组、电针组，每组30人，空白组对梗死侧进行10 min脑电监测，针刺组在针刺得气后立即对梗死侧进行10 min脑电监测，并记录脑电图监测结果，对梗死侧脑电图波幅、频率进行分析。结果：普通针刺组、电针组患者脑电频率较空白组增快，其中电针组差异有统计学意义（P＜0.05），而普通针刺组差异无统计学意义（P＞0.05）；电针组比普通针刺组脑电频率增快，差异有统计学意义（P＜0.05）。普通针刺组、电针组患者脑电波幅较空白组增加，但差异无统计学意义（P＞0.05）；电针组脑电波幅较普通针刺组波幅增加，但两者差异无统计学意义（P＞0.05）。结论：电针治疗缺血性脑卒中患者脑电图波幅、频率不同程度增加、增快，其中频率的变化更有意义，进而从神经电生理方面证实了电针治疗急性缺血性脑卒中有效，脑电图可作为针灸治疗缺血性脑卒中的客观评价手段。%Objective:To assess the effect of acupuncture ,by observing EEG changes of acute ischemic stroke patients.Methods:A to-tal of 90 cases of acute ischemic stroke patients were randomly divided into control group , normal acupuncture group and Electricity Acu-puncture group, 30 coses in each group.Minitoring EEG on infarct side of every group for 10 min, and record the EEG monitoring re-sults, analysis EEG amplitude, frequency on the infarct side of patients.Results:EEG frequency of Normal acupuncture group ,EA group was faster than the control group , in which the EA group difference was statistically significant (P<0.05),while the normal acupunc-ture group showed no significant difference (P>0.05);EEG frequency of electricity acupuncture group was faster than normal group ,the difference was statistically significant (P<0.05).Normal acupuncture group, electro -acupuncture group compared with the control group, the EEG amplitude increased, but the difference was not statistically significant (P>0.05);EEG amplitude of EA group was more obviously increased than normal acupuncture group , but the difference was not statistically significance (P>0.05).Conclusion:EEG amplitude,frequency of ischemic stroke patients by Electro -acupuncture treatment are more increased and faster , which is more meaningful change in frequency , and confirmed EA treatment of acute ischemic stroke are effective from the neurophysiological aspects , thus EEG can be used as objective evaluation tool of acupuncture treatment in treating ischemic stroke .
