[Analgesic effects of electroacupuncture stimulation at different intensities and frequencies].
In the present paper, transient effects and after-effects of electroacupuncture analgesia at the low frequency and low intensity (10 Hz, 3V), high frequency and low intensity (200 Hz, 3V), low frequency and high intensity (10 Hz, 6V) as well as high frequency and high intensity (200 Hz, 6V) were observed in rats. The results show that the transient analgesic effect of the low frequency EA is stronger than that of the high frequency EA and the strong EA is greater than the weak EA. However, the high frequency EA is superior in the after-effect of analgesia to the low frequency EA and the weak EA is to the strong EA.
