TENS therapy (Transcutaneous Electrical Nerve Stimulation) is a non-invasive pain management technique that uses a low-voltage electrical current to relieve pain. TENS therapy involves placing small electrode pads on the skin near the site of the pain. These electrodes deliver a small, safe electrical current to the underlying nerves, which can help to reduce pain signals sent to the brain.

TENS therapy is believed to work by two mechanisms. First, it stimulates the release of endorphins, which are the body’s natural painkillers. Second, it interferes with the transmission of pain signals to the brain, effectively reducing the sensation of pain.

For the foot and ankle TENS therapy is often used to treat arthritic pain and ankle sprains. It is generally considered safe, although it may not be appropriate for people with certain medical conditions, such as pacemakers or epilepsy.
