A study on the characteristics of impedance on Acupoint Hapkok(LI-4, 合谷)

합곡혈(合谷穴)에서의 임피던스 특성에 관한 연구

Measurement of different skin parameters are widely used in the practices and researches of the modern acupuncture. The most important parameter is conductance or impedance. For measurement, some researchers used D.C. and others used A.C. It has been experimentally shown that the acupuncture points and meridian lines have the characteristics of high potential, low electrical resistance, high capacitance, spontaneous sound production, spontaneous light production, and high temperature. The Purpose of this study was to examine the effect of Hapkok(LI-4, 合谷) on experimental frequency characteristics in Hapkok. The result of data analyses indicated that significant differences arise at frequency under 100Hz. We propose that development of Meridian detecting system or Meridian diagnosis system should be done using frequency under 100Hz.
