Which type of therapy is used to help patients relieve pain by placing electrodes on the skin's surface and sending low electrical impuls through this then to a pressure point? ​

Transcutaneous electrical nerve stimulation (TENS) is a therapy that uses low-voltage electrical current for pain relief. You do TENS with a small, battery-powered machine about the size of a pocket radio. Usually, you connect two electrodes (wires that conduct electrical current) from the machine to your skin.
