<p>This invention relates to a method and apparatus for effecting an electrotherapeutic treatment on a living body, and more particularly, to the application of an iontophoretic treatment topically to the skin of a human body. Prior art iontophoretic treatments are known to be accompanied by undesirable effects such as the occurrence of burns in the treated area as well as the formation of undesirable vesicles and bulla, and redness of the skin in the treated area. The present invention provides a method and apparatus for applying an iontophoretic treatment which includes conducting direct current through the skin of the body, and periodically reversing the current and conducting a relatively short pulse of current through the skin in the opposite direction. It has been discovered that by intermittently including relatively short pulses of current in a direction opposite the direction of the normal direct current treatment, the undesirable formation of vesicles, bulla and reddening of the skin in the treated area is greatly reduced or even eliminated.</p> |
