RESUMO
We invented to clarify the influences of acupuncture on the regional skin electroconductivity on humans. An acupuncture needle in situ for a certain time or electroacupuncture using DC 12 volt, 200μA for 7 sec. was applied on the forearm.<br>Measurements of skin electroconductivity were done on several representative points which were distal or proximal to the acupuncture periodically.<br>A needle in situ and electroacupuncture on LI4 did not change the electroconductvity of the proximal skin area around the elbow level on the same extremity.<br>A needle in situ on LI11 increased electroconductivity of the regional skin on the distal area around Manus dorsalis.<br>Electroacupuncture on LI11 increased electroconductivity of the skin on LI5.<br>A needle in situ on LI7 did not change electroconductivity of the skin on the proximal elbow level, but significantly decreased electroconductivity of the skin on LU9.
