A TENS (Transcutaneous Electrical Nerve Stimulation) unit works by delivering powerful pulses through small electrodes, more commonly called TENS electrodes or TENS unit pads placed on the skin. These electrical impulses can help disrupt or block pain signals sent to the brain, essentially acting as a form of pain relief.
Here is a deeper dive on how this pain-relieving handheld unit works:
- Gate Control Theory: According to this theory, the spinal cord contains a “gate” that can open and close to allow pain signals to pass through to the brain. When the TENS unit delivers electrical impulses, it activates sensory nerves that may close this “gate,” preventing the transmission of pain signals to the brain.
- Endorphin Release: Electrical stimulation from a TENS unit can trigger the release of endorphins, which are natural painkillers produced by the body. Endorphins can help reduce pain and produce feelings of well-being.
- Muscle Relaxation: TENS units can also stimulate muscle contractions, which may help relax tense muscles and improve blood circulation in the area. This can alleviate pain associated with muscle tension or spasms.
- Central Nervous System Effects: Some research suggests that TENS may also affect the central nervous system, influencing how the brain perceives pain.
It’s important to note that while TENS units can provide relief for many people, their effectiveness varies depending on the individual and the type of pain being treated. Additionally, TENS units are generally considered safe when used correctly, but it’s essential to follow the instructions provided by healthcare professionals to avoid any potential risks or adverse effects. Our most popular and effective TENS unit is the EMPI Select TENS Package.
