What is the function of Transcutaneous Electrical Nerve Stimulation (TENS)?

Transcutaneous Electrical Nerve Stimulation (TENS) is primarily utilized to manage pain, particularly chronic pain. It works by sending low-voltage electrical impulses through electrodes placed on the skin, which can help alleviate pain by disrupting the pain signals sent to the brain. This mechanism may also stimulate the production of endorphins, which are the body's natural pain relievers.

The primary goal of TENS is therefore to reduce pain symptoms, making it an effective intervention for individuals suffering from various types of chronic pain conditions, such as arthritis, neuropathy, and postoperative pain. While other options involve important therapeutic goals in rehabilitation and physical therapy, they are not the primary functions of TENS, which is specifically targeted toward pain relief.
