Medi-Stim’s Sof-Stim electrodes are ideal for patients with sensitive skin or elderly patients with thin, delicate skin. Sof-Stim electrodes are made with a tan tricot knit material, highly conductive silver-coated carbon film, and feature a unique soft, blue-colored patented Polyhesive® gel that allows more oxygen to permeate through the gel to the skin. It is softer than most conventional gels, making electrode removal easier and gentler on the skin. Sof-Stim electrodes also work well in hairy areas. as the thick soft gel can penetrate through the hair and adhere better to the skin. Available in two sizes with pin wire connector. Made in USA. Approximately 15-20 applications.
