A to Z of MS Functional electrical stimulation (FES)
In MS, scarring on the central nervous system prevents or interrupts messages passing to or from the brain. This can cause muscle stiffness (spasticity), weakness and poor coordination in limbs. People with MS can experience problems such as a dropped foot or instability and weakness at the hip and knee. These factors contribute to reduced mobility and increased fatigue as more energy is expended in moving about.
Functional electrical stimulation (FES) applies electrical stimulation to unresponsive or weak muscles and forces functional movement. To be suitable for the treatment, the individual needs to be able to walk, even if only a few metres with a stick or crutch. By wearing a foot switch triggered stimulator, the person with MS - with corrected dropped foot - can maintain use of walking muscles for longer.
FES is a recommended NHS treatment in individuals with an upper motor neuron lesion, such as people who have had a stroke. However, the lack of trials specifically for FES use in MS has lead to uneven provision in the UK. To address this, a rigorously designed and conducted trial to investigate the effect of FES on mobility and quality of life in people with MS is underway. The trial is being funded by the MS Trust.
