Investigation of the electrical impedance of acupuncture points and non-acupuncture points before and after acupuncture, using a four-electrode device

Aim To evaluate the effect of acupuncture on skin electrical impedance of selected points, before and after acupuncture on one acupuncture point (PC6), using a four-electrode device. Methods Six acupuncture and non-acupuncture points on both sides of the body were selected to evaluate the effects of acupuncture on electrical properties of these points. Results There were no results significant differences of electrical impedance before and after acupuncture in the selected points. Conclusions According to our experimental set-up, acupuncture at one point without stimulation does not alter skin electrical impedance in healthy volunteers and there is no difference between acupuncture points and non-acupuncture points.
