120Z Dual-Channel TENS Unit

(1 customer review)

TENS 120Z is a 2 channel electric stimulator for relief from muscular spasms, pain, and joint contracture.

Transcutaneous Electric Nerve Stimulation, TENS, this small battery-powered machine impacts muscular pain by using electrical impulses to stimulate nerve endings under the skin, this, in turn, helps block the pain signals to the brain. A TENS machine does not cure the problem causing the pain but it can reduce the pain which can then aid the healing process.

  1. Paul King

    I bought this to loan out to patients with lower back pain. It’s easy to use, small and lightweight, and not a gimmick-type device that just ‘tickles’. This unit really helps my patients manage pain. Thank you EMS
