TENS stands for transcutaneous electrical nerve stimulation. It is most commonly used for the management of pain. It does this in two ways. It can stimulate your mechanically sensitive nerves which block pain signals from reaching your level of awareness. The other mechanism is by stimulating the naturally occurring endorphins (pain relieving chemicals)in your body.
TENS is always an adjunct to treatment, meaning that it allows you to tolerate some exercise and activities so that you can progress toward your goals. It is not a ‘ stand alone’ treatment approach unless pain management is your goal.
