The gate theory of pain states that before reaching the brain, pain messages pass through a series of nerve “gates” in the spinal cord. Non-painful input can close these gates to painful input, thereby preventing the sensation of pain from traveling to the brain.
Treatments such as transcutaneous electrical nerve stimulation (TENS) can “override” pain messages that are also traveling to the central nervous system and help with pain. This white paper discusses TENS technology, how it works, and the advantages this treatment has over alternative pain management techniques. Download the paper for more information.
