Abstract

BackgroundDue to controversially discussed results in scientific literature concerning changes of electrical skin impedance before and during acupuncture a new measurement system has been developed.

MethodsThe prototype measures and analyzes the electrical skin impedance computer-based and simultaneously in 48 channels within a 2.5×3.5 cm matrix. Preliminary measurements in one person were performed using metal needle and violet laser 405 nm acupuncture at the acupoint Kongzui LU6. The new system is an improvement on devices previously developed by other researchers for this purpose.

ResultsSkin impedance in the immediate surroundings of the acupoint was lowered reproducibly following needle stimulation and also violet laser stimulation.

ConclusionsA new instrumentation for skin impedance measurements is presented. The following hypotheses suggested by our results will have to be tested in further studies: Needle acupuncture causes significant, specific local changes of electrical skin impedance parameters. Optical stimulation violet laser at an acupoint causes direct electrical biosignal changes.
