Transcutaneous electrical nerve stimulation
In pain medicine, transcutaneous electrical nerve stimulation (TENS) is "the use of specifically placed small electrodes to deliver electrical impulses across the skin to relieve pain. it is used less frequently to produce anesthesia." The mechanism of action is not fully understood.
Some evidence suggests that it shares modes of action with some types of acupuncture. While TENS generators are usually small battery-powered devices worn by the patient, higher-voltage elecrostim units are used by physical therapists and other practitioners.
