Functional Electrical Stimulation
Also written as: FES — Functional Electrical Stimulation
A therapeutic modality in which electrical currents activate paralysed or weakened muscles during functional tasks such as walking or grasping.
Full Definition
Functional Electrical Stimulation (FES) involves the application of precisely timed electrical pulses to peripheral nerves or muscles to elicit contractions that contribute to a purposeful movement, as opposed to purely therapeutic stimulation at rest. It is used in the rehabilitation of patients with spinal cord injury, stroke, and other neurological conditions to restore or augment motor function. FES differs from Transcutaneous Electrical Nerve Stimulation (TENS) in that FES is designed to produce functional muscle contractions during activity rather than for analgesia. Editors should note that 'FES' is already listed as an excluded term; the full form 'Functional Electrical Stimulation' requires title-case treatment and should be expanded before its acronym on first use.
Usage
Usage note: Do not conflate with TENS (analgesic) or NMES (muscle re-education at rest). FES is specifically characterised by functional task integration. The acronym FES is already common in clinical literature; always expand on first use.
