Our Galva-Stim reusable self-adhering electrodes are made of a white foam top, a moderately aggressive gel, and a highly conductive silver-coated carbon liner. The larger “dispersive” or “grounding” pad is usually placed on the back or thigh. The smaller “active” pads are placed over the actual treatment site. These are low in profile and conformable and available in pin-wire connection. Lasts 10-15 days/applications.
