A TENS (Transcutaneous Electric Nerve Stimulation) unit is a small, battery-powered, portable muscle stimulation machine that can be used at home to help control pain.
How TENS Works
Variable intensities of electric current are used to control pain. This treatment is recommended to help patients get through periods of severe acute neck pain, back pain, muscle spasms, and knee pain — especially for runners.
When TENS Is Recommended
TENS units are typically not recommended for chronic pain. They’re best suited for acute, severe pain episodes where portable, at-home pain control can help a patient manage symptoms between office visits.
