Abstract
Abstract Disclosed herein is a method and device for the therapeutic treatment of living tissue to assist in the healing of biological traumas and providing treatment of conditions such as arthritis. Positive square wave current pulses are applied between two electrodes positioned on the skin of the patient, one of the electrodes being provided with a concentric electromagnet to produce a magnetic field which forces the applied current into the tissues being treated.
