This is the device that uses transcutaneous electrical nerve stimulation (TENS) and electrical muscle stimulation (EMS) to help ease pain and improve muscle strength. The TENS therapy provides drug-free pain relief by stimulating the nerves and blocking pain signals to the brain, while EMS engages muscle contractions to accelerate strengthening and rehab. It has six TENS modes and six EMS modes which can be used together or independently. Includes remote and two sets of electrode pads. Charges via USB. Not for use by those with pacemakers.
