This is versatile wrap that uses electrical muscle stimulation (EMS), compression, and hot or cold temperatures to help ease pain and improve muscle strength. Ideal for individuals struggling with arthritis, stiffness, or injuries, it provides drug-free pain relief and can be used on various parts of the body including shoulders, hips, elbows, knees, and the back. It employees EMS therapy to engage muscle contractions that accelerate strengthening and rehab while compression and its self-heating fabric help improve circulation, reduce swelling, and temporarily relieve pain. It also comes with a gel pack that can be chilled in a freezer or warmed in a microwave then slipped into an insulated pouch. The wrap has five massage modes (Shiatsu, relaxing, soothing, calming, kneading) and ten intensity levels. It secures with hook-and-loop fasteners and is designed for 20-minute sessions. Charges via USB. Not for use by those with a pacemaker.
