FES
Also written as: FES — Functional Electrical Stimulation
Abbreviation for Functional Electrical Stimulation; the use of controlled electrical pulses to activate paralysed or weakened muscles for therapeutic or functional purposes.
Full Definition
FES stands for Functional Electrical Stimulation, a technique fundamental to advanced orthotics and rehabilitation medicine. It is used in devices such as peroneal nerve stimulators for foot-drop correction and upper-limb neuroprostheses. In editorial work, FES must be distinguished from TENS and NMES, which, while related, serve different clinical purposes. The acronym should be defined at first mention in any document. In orthotics literature, FES devices may be classified as orthoses or prostheses depending on their mechanism and scope, and editors should not assume one classification without checking the source document.
Usage
Usage note: Always expand on first use. Verify context to distinguish from TENS (pain relief) and NMES (muscle re-education without a functional output goal).
