More recently, many TENS units use a mixed frequency mode which alleviates tolerance to repeated use. 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. A typical battery-operated TENS unit is able to modulate pulse width, frequency, and intensity. The unit is usually connected to the skin using two or more electrodes which are typically conductive gel pads. 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 reduce pain. Transcutaneous electrical nerve stimulation ( TENS or TNS) is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes.
