TENS is short for trans-electrical nerve stimulation, and these small battery-operated units can produce a current that's suitable for blocking pain.

That's their main use in a physiotherapy situation. There are two ways in which TENS is used: a conventional TENS uses a faster frequency, and the electrode placement of the unit is generally around the area where the pain is felt.

Secondary to that is what is called acupuncture TENS, and that's a lower frequency of two to four hertz. There the goal is muscle stimulation and activation, and the way that works is by producing an endorphin-like response in the body.

If you have questions about TENS machines, contact a local physiotherapist.
