FES
Functional Electrical Stimulation (FES)

Functional electrical stimulation (FES) is a medical technology using the application of low-level electrical impulses to various structures of the body. In rehabilitation, FES is primarily used for activating the neuromuscular system.

FES may be used for purely functional, or therapeutic purposes. Functional use implies the activation or enhancement of motion in a functional activity as a replacement for lost or impaired motor control. Using the Handmaster for grasping a cup for drinking is an example of the functional application of FES. Therapeutic use is directed towards lessening impairments, prevention of secondary complications, or halting progression of a disabling condition. Therapeutic FES includes strengthening muscles, lessening of spasticity, preventing muscle atrophy, and improving regional blood flow.

FES is useful in disabilities and disorders characterized by impaired motor control based on a central nervous system disorder or trauma, and intact peripheral innervation.  As noted, FES may be used as a neuro prosthesis to replace lost function and as a therapeutic modality. FES is used in spinal cord injuries, stroke, brain injuries, multiple sclerosis, and cerebral palsy.
