The Cardinal Health Uni-Patch Re-Ply Stimulating Electrode is a reusable, self-adhesive electrode designed for pain relief and muscle stimulation through TENS, NMES, and FES units. Its comfortable, low-profile design and durable construction allow for multiple uses, saving time and money. Made from conductive carbon, the electrode ensures optimal signal transmission for effective electrical stimulation and long-lasting results. The rectangle shape (2" x 4") enables targeted application to specific pain points or muscle groups. Benefits include pain reduction, improved muscle function, enhanced circulation, and non-invasive pain relief. Applications range from back and neck pain to sciatica, muscle spasms, sports injuries, and arthritis. Each package contains four loose-packed electrodes for effective pain management and muscle rehabilitation.
