Pronunciation

Transcutaneous: /ˌtrænskjuːˈteɪniəs/ Electrical: /ɪˈlɛktrɪkəl/ Nerve: /nɜːrv/ Stimulation: /ˌstɪmjʊˈleɪʃən/

Etymology

The term "Transcutaneous" is derived from the Latin words 'trans' meaning across, and 'cutis' meaning skin. "Electrical" comes from the Greek word 'ēlektron' meaning amber, from which electricity was first produced. "Nerve" is derived from the Latin word 'nervus' meaning sinew, and "Stimulation" comes from the Latin word 'stimulus' meaning goad.

Definition

A Transcutaneous Electrical Nerve Stimulation (TENS) machine is a device that uses electrical currents to relieve pain. The machine is usually connected to the skin using two or more electrodes. These electrical currents are believed to reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles.
