ABSTRACT The inhibitory component of the skin against given electrical current, also called as the electrical skin resistance, is subject to change in response to many factors, especially pain. In order to find out more definite relationship between pain and skin resistance, one should make measurement in the state devoid of any external disturbing stimuli to get the "basal skin resistance (BSR)", which is known to be different from point to point on body surface. Also, the "active points" have more consistent BSR characters than other points and most of them share same locations with "acupuncture points" which is easy to localize accurately and repeatedly in normal subject. Therefore, the comparison of BSR of certain acupuncture points of normal subject and pain-suffering subjects is expected to be able to figure out any pain-induced BSR changes. Our measurement at 16 acupuncture points (asymmetrical 8 pairs) of 10 normal subjects showed inconsistently asymmetrical distribution of the BSR values with significant order among themselves including left SP (spleen)-6 at their lowest position, but neither the measuring system itself nor any of the 16 points was statistically reliable enough for diagnostic purposes. So the measuring device needs to be improved with after evolution, and more acupuncture points need to be explored to complete our pain-related BSR map. In addition, the meaning of the above BSR distribution pattern is waiting to be explained through such efforts.
