Electroacupuncture: Current Strength-Duration Relationship For Initiation of Hypesthesia In Man

Abstract

Electrical stimulation through an acupuncture needle in a Chinese point of the human hand decreased the subjectively estimated sensation elicited by noxious and by tactile stimulation of the ipsilateral finger. A hyperbolic relationship was found between the stimulus duration (T, ses) required for the initiation of hypesthesia and the intensity of current (I, mA) passed through the acupuncture needle: I=0.11+18/T
