TENS
Pronunciation: tenz
Also written as: TENS — Transcutaneous Electrical Nerve Stimulation
Transcutaneous Electrical Nerve Stimulation; a non-invasive modality delivering low-voltage electrical current through the skin to modulate pain.
Full Definition
TENS is an electrophysical modality widely used in PM&R for the management of acute and chronic pain. Small electrode pads placed on the skin transmit mild electrical impulses that are thought to interfere with pain signal transmission via gate-control mechanisms and endorphin release. In clinical documentation, TENS must be distinguished from NMES (neuromuscular electrical stimulation), which targets motor rather than sensory nerve fibers. Editors reviewing rehabilitation protocols should confirm the acronym is expanded on first use and that electrode placement and parameter settings are described consistently. The abbreviation is always written in full capitals.
Usage
Usage note: Always expand on first mention in clinical and research documents. Do not conflate with NMES or EMS, which target motor pathways.
In Context
- "TENS was initiated at 80 Hz for the management of lumbar radicular pain unresponsive to oral analgesics." — Pain management clinical note
- "The protocol incorrectly referred to TENS as 'muscle stimulation'; the editor corrected this to distinguish it from NMES." — Rehabilitation research protocol review
