不同电针刺激频率对脑卒中患者脑血流灌注和脑功能的影响

目的:寻找治疗脑卒中的适宜电针刺激频率.方法:47例脑卒中患者电针头皮运动区,根据其频率分为2 Hz、2/15 Hz、100 Hz组,应用单光子发射型计算机断层(SPECT)观察3组患者电针前和电针中脑血流灌注和脑功能的变化.结果:三种不同的电针刺激频率均能改善脑卒中患者的局部脑血流灌注和脑细胞功能活动,2/15 Hz和100 Hz组较2 Hz组为强.结论:在刺激强度固定的条件下,2/15 Hz、100 Hz的刺激频率治疗脑卒中疗效较好.

Effects of electroacupuncture of different frequencies on cerebral blood perfusion and cerebral function in the patient of stroke

Objective To explore effects of electroacupuncture of different frequencies on stroke. Methods Forty-seven cases of stroke were treated with electroacupuncture at the motor region of the scalp and divided into 2 Hz, 2/ 15 Hz and 100 Hz groups according to the used frequency. Cerebral blood perfusion and brain functions before and during electroacupuncture in the 3 groups were investigated with single photon emission computed tomography (SPECT). Results Local cerebral blood perfusion and brain cell functions could be improved by electroacupuncture of the 3 frequencies, and the actions of 2/ 15 Hz and 100 Hz were better. Conclusion Electroacupuncture of 2/15 Hz and 100 Hz has a better therapeutic effect on stroke when the stimulating intensity is fixed.
