Abstract
A method, and typically a pair of treatment electrodes energized at opposite electrical polarity, is provided for applying electricity to the human body. At least the area of the negative electrode in contact with the skin is covered with felt-like material, preferably moistened, and having a thickness in excess of three millimeters. Compliance with a current-time limitation according to the method essentially avoids iontophoretic burns. Electively, this negative electrode structure allows increasing the size of the positive electrode, permitting a larger treatment current with reduced discomfort. Intermingled positive and negative electrodes may be used.
