What are some discount retailers of electronic muscle stimulators?

Electronic muscle stimulators, sometimes known as EMS or TENS units, are available at discount retailers such as Wal-Mart and at Internet sites such as Amazon.com. Both retailers feature electronic muscle stimulators by brands such as AccuRelief, Omron and truMedic.

Electronic muscle stimulators differ from transcutaneous electrical nerve stimulation, or TENS units, in that electronic muscle stimulators are more directed at specific muscles to relieve soreness, stiffness and pain associated with swelling and edema, as well as increasing blood circulation and movement in muscles suffering from inactivity or atrophy, while TENS units send electrical impulses through the skin to nerves and block the pain signals sent to the brain by the location of the injury. They are generally more effective in treating more chronic conditions and forms of pain.
