Based on the idea that organ system functions are reflected in galvanic currents on the skin surface, electrodermal testing has become a very popular "alternative" diagnostic technique. Available data suggest that there are electrical currents on the skin, and one study shows that ET can, indeed, detect internal problems. But data are scant, and there's no evidence this controversial technique can identify specific causes of internal problems, as ET practitioners often claim it can.
