Abstract:

The stimulative effect of supracutaneous electroacupuncture using a blunt-tip electrode on 120 points of human skin was observed in 12 healthy volunteers. A comparison of stimulation by the more expensive supracutaneous instrument specifically designed for this treatment and that of the more conventional transcutaneous electroacupuncture instrument, modified by use of a blunt-tip, belt-type electrode instead of the traditional electro-needle, showed similar therapeutic effects. An animal experiment, using the rat tail flick analgesia method to compare supracutaneous electroacupuncture, showed that the pain threshold was raised by both types of electroacupuncture, with both having an optimal stimulation time of 10–20 minutes. The percentage of change in maximum pain threshold was 206.6% for supracutaneous electroacupuncture at 7V and 175.4% for transcutaneous electroacupuncture at 2V.
