TENS Unit

Transcutaneous Electrical Nerve Stimulation is a generic name for a method of nerve stimulation designed to control pain. There are now a variety of TENS units designed for specific modes of application. The different modes are identified by their parameter ranges of amplitude, frequency and pulse width. The units are small, battery powered, and light weight weighing only a few ounces. Electrodes are placed on the skin near the area of pain and are attached to the TENS unit. A physical therapist/assistant instructs the patient on the positioning of the electrodes and the duration and frequency of the treatment and also sets the parameters for the amplitude, frequency and pulse width based on the patient's individual needs. The TENS unit is used at home by the patient for use as instructed as part of a comprehensive treatment program designed for the appropriate management of pain.
