不同强度和频率电针的镇痛效应

ANALGESIC EFFECTS OF ELECTROACUPUNCTRE STIMULATION AT DIFFERENT INTENSITIES AND FREQUENCIES

本文观察了低频弱电针(10赫兹,3伏)、高频弱电针(200赫兹,3伏)、低频强电针(10赫兹,6伏)和高频强电针(200赫兹,6伏)的即时镇痛效应和镇痛后效应。结果表明,低频电针的即时镇痛效应优于高频电针,强电针优于弱电针;而高频电针的镇痛后效应优于低频电针,弱电针优于强电针。

In the present paper,transient effects and after-effects of electroacupunctureanalgesia at the low frepuency and low intensity (10 Hz,3V),high frequencyand low intensity (200 Hz,3V),low frepuency and high intensity (10 Hz,6V) aswell as high frepuency and high intensity (200 Hz,6V) were observed in rats.The results show that the transient analgesic effect of the low frepueney EA isstronger than that of the high frepuency EA and the strong EA is greater thanthe weak EA.However,the high frepuency EA is superior in the after-effectof analgesia to the low frepuency EA and the weak EA is to the strong EA.
