What is a TENS Machine?

TENS is an abbreviation of Transcutaneous Electrical Nerve Stimulation.

Transcutaneous means “across the skin”. In simple terms, a tens machine stimulates your nerves via an electrical current through your skin. A TENS machine is an electronic medical device. A TENS machine may assist you in modest short-term pain relief.

The use of a TENS machine should be as one part of a pain management program under the guidance of your doctor or healthcare practitioner. Please consult your healthcare practitioner before using a TENS machine.

How Does a TENS Machine Provide Short-Term Pain Relief?

Researchers believe that TENS controls pain in one of two ways:

Sensory Level Stimulation – The Gate Control theory of pain means that the electrical input of the TENS machine interferes with the transmission of pain signals, by blocking the neural “gate” through which the pain travels.

Motor Level Stimulation – The goal of motor level stimulation is to cause the release of the body’s opiate-like substances to achieve pain relief.
