Available only from Hammacher Schlemmer, this is the device that uses transcutaneous electrical nerve stimulation (TENS) and electrical muscle stimulation (EMS) to help ease pain and improve muscle strength in the feet and legs. 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. The stimulator has eight EMS modes, 17 TENS modes, and 99 intensity levels which can be used together or independently. Includes remote and two sets of electrode pads. AC plug; requires two AAA batteries for remote. Not for use with pacemakers. 16 3/4" L x 16 3/4" W x 6" D. (4 1/2 lbs.)
