The Evolution of the TENS Unit

Posted by Leigh MacKenzie, November 6, 2013

By definition, Transcutaneous electrical nerve stimulation (TENS) is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes. TENS by definition covers the complete range of transcutaneously applied currents used for nerve excitation although the term is often used with a more restrictive intent, namely to describe the kind of pulses produced by portable stimulators used to treat pain. The unit is usually connected to the skin using two or more electrodes. A typical battery-operated TENS unit is able to modulate pulse width, frequency and intensity. Generally TENS is applied at high frequency (>50 Hz) with an intensity below motor contraction (sensory intensity) or low frequency (<10 Hz) with an intensity that produces motor contraction.

Electrical stimulation for pain has been around since 63 A.D. in ancient Rome. For some, pain was relieved by standing on an electrical fish at the seashore and hoping for the best. Eventually, electrostatic devices were used for headaches and other pains in the 16th century through to the 18th century. By the 19th century a device called the electreat, was used to manage pain and cancer cures.

Today, there are many TENS units on the market to choose from. A great product to shop for is the Mojility 1000-TENS.
