A TENS (Transcutaneous Electrical Nerve Stimulation) unit is a device used to relieve pain through the application of low-voltage electrical currents to the skin. The device consists of small electrodes that are placed on the skin near the area of pain. These electrodes deliver electrical impulses that stimulate the sensory nerves, which can help to block pain signals from reaching the brain. The electrical impulses also promote the release of endorphins, the body’s natural painkillers, which can further help reduce discomfort. TENS units are commonly used for conditions such as chronic pain, arthritis, muscle strain, and neuropathy.
The TENS unit is non-invasive and is typically considered safe for most individuals. It is a portable device that can be easily adjusted for different intensity levels and used at home or in a clinical setting. TENS therapy does not cure the underlying cause of pain, but it can provide temporary relief, making it a helpful adjunct in managing chronic pain. The device is generally used for short-term pain relief, and while it is not suitable for everyone, many people find it effective for reducing discomfort and improving their quality of life.
