Functional Electrical Stimulation (FES)

Online Article

Functional electrical stimulation (FES) is a treatment that applies small electrical charges to a muscle that has become paralysed or weakened, due to damage in your brain or spinal cord. The electrical charge stimulates the muscle to make its usual movement. In MS it is mostly used as a treatment for foot drop, where disruptions in the nerve pathways between the legs and brain mean the front of your foot cannot be lifted to the correct angle when walking.

FES was first developed in the United States in the 1960s, where it was initially tested in stroke patients. Although early results were promising, it wasn’t used regularly in clinical practice until much later, as it was very much seen as an experimental treatment. Research on its use in stroke for both foot drop and to assist finger movements, was first published in the late 1970s. In the mid-1980s, a group based in Salisbury in the UK started to look at using FES. Originally their work was in people with spinal cord injuries; from this initial work they went on to develop devices for people with MS in the early 1990s and it continues to be used today.

FES is currently being investigated to see if the technique can help with swallowing, hand and arm function, and even breathing problems for pulmonary disease patients and for stroke patients. It has a number of potential future uses in MS
