Objectives: Studies have shown that meridians have better conductivity and higher propagate of electromagnetic wave. The conductivity can be represented by the peak value of current, and the propagate of electromagnetic wave can be described by polarization. Bilaterally opposite, symmetric acupunctures along he meridians or branching meridians are two analgesic methods commonly used in acupuncture. The purpose of this study was to detect whether there was an electrical difference between the bilateral symmetric acupoints and the asymmetric acupoints, and to analyze the directionality of current.
Methods: 62 subjects were included in this study and then randomly divided into two groups. Group A have 30 subjects (14 males and 16 females) with an average age of 28.6±9.7 and 32 subjects were in group B (15 males and 17 females) with an average age of 26.9±8.6. 1.5V DC voltage is regulated by personal computer, measuring instrument and computer connection, access in 14 seconds, 640 voltage readings are directly input the computer to convert into current, and the current peak (conductivity) is calculated and the percentage change of difference (polarization) is calculated. The symmetry groups were Wai-Kuan (left and right) and Ta-Ling (left and right). The asymmetric group is the left Tien-Ching and the right Wai-Kuan, the left Ta-Ling and the right Kung-Tsui, and the right Ta-Ling and the left Kung-Tsui. The data were analyzed by paired-t test and ANOVA test.
Results: The current flows from the right arm to the left arm with a higher electric conduction and lower dielectric polarization than left to right. Bilaterally symmetric pairs of acupoints have higher electric conduction and lower dielectric polarization than the asymmetric ones. Statistics showed all the significant difference.
Conclusions: These results show that a morphologically symmetric human body is asymmetrical in its conduction and polarization, and bilaterally symmetric acupoints have a better conduction and worse polarization than the asymmetric ones. The better conduction between two points means that they have a better information connection and the worse polarization between two points means that
they have electromagnetic wave propagation quickly.
