Transcutaneous Electrical Nerve Stimulato

A Transcutaneous Electrical Nerve Stimulator, more commonly referred to as a TENS unit is an electronic device that produces electrical signals used to stimulate nerves. he current may be delivered intermittently. The mild electrical current generates heat that serves to relieve stiffness, improve mobility, and relieve pain. The treatment is believed to stimulate the body’s production of endorphins or natural pain killers.

TENS units are sometimes used in an attempt to alleviate neuropathic pain. Although results are modest, some patients benefit from this approach. However, a study published in the New England Journal of Medicine found that TENS therapy was no more effective against chronic lower back pain than a placebo.
