How Do I Choose a Tens Unit?
Transcutaneous electrical nerve stimulation (TENS) uses low-voltage electrical stimulation through electrodes hooked to a machine to block pain signals from reaching the brain. TENS units for home use are available through pharmacies, online retailers and medical supply companies. Some insurance companies will cover the cost of a TENS unit in part or in full with a doctor’s prescription, though a prescription is not necessary to purchase a unit.
