All natural drug free wearable technology. iReliev packs a powerful punch of clinically proven electrotherapy in one portable system. Its combination of Transcutaneous Electrical Nerve Stimulation (TENS) and Electrical Muscle Stimulation (EMS) offers the benefits of both pain relief and muscle conditioning. EMS stimulates the nerves surrounding muscles through medical grade electrode pads by softly contracting and relaxing them while TENS delivers impulses that trigger a natural response that blocks pain signals, leading to fast targeted pain relief. This innovative technology is designed to be wearable, comfortable and highly portable. Get back to the sport you love or in game of life with the iReliev Therapeutic Wireless System. Intelligent Wearable Therapy: iReliev delivers a prescription equivalent TENS and EMS combination device which offers these two distinct types of beneficial therapy through an easy-to-use wireless and untethered experience. We firmly believe that the all-new iReliev Therapeutic Wireless System is the simplest device on the market, free from the hassles of wires or set up that is typical of other portable devices. iReliev has Taken Portable Electrotherapy to the Next Level: iReliev Therapeutic Wireless System features rechargeable batteries, a blue LED backlight, plus 14 preset therapy modes for acute to chronic pain, arthritis, muscle strength and recovery. It’s the latest in wearable, on-the-go therapy and makes treating pain and conditioning muscles easier than ever.
