The stimulative effect of electro-blunt-tip needle (a kind of electroacupuncture stimulating on the surface of skin point) on the 120 points of human skin was observed in 12 healthy volunteers. It was shown that the substitute typical electro-blunt-tip needle stimulator and its special pen-like electrode by a general electroacupuncture stimulator and a tape-like adjustable electrode and similar therapeutic effects. It was found in animal experiment that the pain threshold determined with rat tail flick analgesia method was raised by electroacupuncture and electro-blunt-tip needle, the optimal stimulating time being 10-20 minutes for both, the percentages of the maximal changing pain threshold being 206.6% and 175.4%, and the corresponding voltage being 2v and 7v respectively.
