TENS stands for transcutaneous electrical nerve stimulation. It is a method of pain relief that involves the use of a mild electrical current delivered through a small, battery-operated device known as a TENS machine. This device has leads connected to sticky pads called electrodes, which are placed on the skin in specific areas. The electrical impulses from the TENS machine can help reduce pain and muscle spasms caused by various conditions such as arthritis, period pain, pelvic pain caused by endometriosis, knee pain, sports injuries, and more.
TENS therapy works by delivering small electrical impulses through electrodes attached to the skin, which can block or change the perception of pain. It is believed to work by activating nerves to decrease pain and may help release pain-reducing chemicals produced by the body. TENS is considered a noninvasive method for relieving pain and may allow some individuals to reduce their intake of pain medications, which can be addictive or cause adverse side effects.
TENS is generally used for chronic pain and is most effective when used for at least 30 minutes during activities such as walking, doing chores, or exercise. It is less effective when a person is sitting still, lying down, or resting. TENS units are available for purchase at pharmacies and retail stores, with prices ranging from about £20 to £100. It is important to adjust the settings correctly for individual conditions to get the most benefit from TENS.
In summary, TENS is a method of pain relief that uses electrical currents to alleviate various types of pain, and it is considered a low-risk pain relief option for many people. However, more research is needed to fully understand its effectiveness and mechanisms of action.
