[Survey of studies on the electromagnetic characteristics of acupoints and meridians]

The present paper reviewes the literatures on the electromagnetic characteristic of meridians at home and abroad in the last twenty years. It generally summarize the studies on the electromagnetic characteristic of meridians from the aspects of the imaging of meridians, the electromagnetic model of meridians, and the physiological and pathological observations on the electro changes at acupoints. The results indicate that acupoints apparently have electro characteristics which are associated with the change of the health condition, time, environment, etc. By means of electromagnetic characteristic, the image of meridians can be made and the phenomena of meridians can be clarified, the essence of meridians can be explained in a certain degree. It still demands further research on this characteristic of meridians.
