TENS or Transcutaneous Electrical Nerve Stimulation are machines with different adjustable settings to control the intensity of stimulation by controlling the low-voltage electric currents to treat pain. Electrode pads placed on the body at the site of pain deliver electricity that travels through the nerve fibers. A TENS unit is used as a safe, noninvasive, drug-free method of pain management. A TENS unit can offer a better quality of life for people with pain
TENS unit relieve pain in two ways.
1. One method is called The Gate Control Theory. Soothing pulses are sent from the TENS unit through the pads to the skin. The pulses then travel along the connecting nerve fibers, suppressing pain signal to the brain. There is a neural mechanism that acts as a kind of gate. Whether the gate is open, closed, or partially closed depends on what sort of signal it receives from the brain to change the perception of pain in the user’s body, and help block the pain message transmission to the brain.
2. Another way is by releasing the endorphin in the user’s body. The electrical impulses stimulate the production of endorphins in the body. These natural morphine-like substances block pain messages from reaching the This is a drug-free natural option without the danger of dependence or other side effects.
