TENS
Also written as: TENS — Transcutaneous Electrical Nerve Stimulation
Abbreviation for Transcutaneous Electrical Nerve Stimulation, a modality used in rehabilitation to manage pain by delivering low-voltage electrical current through the skin.
Full Definition
TENS involves the application of electrical impulses via surface electrodes placed on the skin to modulate pain signals, typically by stimulating large-diameter sensory nerve fibres that inhibit pain transmission in the spinal cord (gate control mechanism). It is a common adjunctive modality in physiotherapy and physical medicine, used for conditions including musculoskeletal pain, neuropathic pain, and post-operative pain management. Editors should ensure TENS is consistently capitalised as an acronym on first use and expanded parenthetically. It should be distinguished from NMES (neuromuscular electrical stimulation), which targets motor nerves to produce muscle contractions rather than primarily targeting pain pathways.
Usage
Usage note: Always capitalise. Distinguish from NMES (motor nerve stimulation) and FES (functional electrical stimulation for movement).
