This provides relief, especially from overused muscles.

Understanding Pain Signals

To fully utilise the benefits of TENS, it is important to comprehend how pain signals work in the body. Pain is a complex sensation that involves various physiological and neurological processes. When tissue damage or injury occurs, specialised nerve endings called nociceptors are activated. These nociceptors send electrical signals to the brain through the spinal cord.

A TENS machine stimulates the sensory nerves to interfere with the pain signals travelling to the brain. This is based on the Gate Control Theory of Pain, which suggests that electrical stimulation can close the “neural gates” in the spinal cord.
