Analysis of Meridian Flow Direction by Electrical Stimulation Method

Abstract

AbstractMeridians constitute the theoretical foundation of acupuncture in traditional Chinese medicine (TCM), and they have been described for 2000 years. Classical TCM advocates for the directionality of meridians. Finding an accurate method to verify this directionality is an important goal of TCM doctors and researchers. In this study, we objectively explored the physical properties of meridians, such as response current from electrical stimulation, to explore their directionality. The Agilent B1500A semiconductor measurement analyzer was utilized to input the alternating current waveforms and detect the response current on the meridians. The results showed that the direction of the meridians influences the intensity of the response current. Therefore, the mechanisms behind the directions of ion transportation and the meridians were investigated using the response time and the intensity of the response current. Thereafter, we propose a model to explain this mechanism. Afterward, a comparison between the direction of the meridian in this experiment and ancient Chinese medicine classics was performed.
