Pain relief or suppression is achieved by: Suppressing the transmission of pain in nerves (Gate Control Theory) and increasing the discharge of the body's endorphins, which reduces the sensivity to pain in the central nervous system (Opiate Release Theory). The Hollywog® WiTouch's® exclusive and patented waveform incorporates BOTH clinical theories of TENS to provide immediate and long-lasting pain relief. The Hollywog® WiTouch® provides a safe, easy to apply, medically approved pain management system for self-treatment when needed. The WITouch® is perfect for those with chronic low back pain. The function of TENS is really pretty straightforward. It works by suppressing the transmission of nerve pain (called Gate Control Theory), and reducing the sensitivity of pain (called Opiate Release Theory). The WiTouch accomplishes this while being small, lightweight and discreet. Its thin and flexible design allows the WiTouch to contour perfectly over the surface of the back for a perfect fit on virtually anyone. You can wear it under your clothes for treatment on your own schedule without any wires!
