A transcutaneous electrical nerve stimulation (TENS) unit is a device that sends small electrical currents to targeted body parts. These currents are used to relieve pain. Some TENS units are designed ...

Even though researchers disagree on its effectiveness for lower back pain, they consider transcutaneous electrical nerve stimulation (TENS) safe with a low risk of complications. Learn where to place ...

A TENS machine is small -- about the size of an iPad mini. It’s connected to a series of electrodes, which are put on your skin to deliver a low-voltage electrical charge. The electrical pulses ...

A transcutaneous electrical nerve stimulation (TENS) unit works by delivering small electrical impulses through electrodes with adhesive pads to attach them to a person’s skin. Research has not proven ...
