In this article, the author talks about functional electrical stimulation in children and adolescents with cerebral palsy. Functional electrical stimulation (FES) is defined as the electrical stimulation of muscles that have impaired motor control, in order to produce a contraction to obtain functionally useful movement. It was first proposed in the 1980s as a treatment option in children with cerebral palsy (CP). The most common application, at least in the adult stroke population, is FES applied to the dorsiflexors during the swing phase to prevent drop foot which could lead to tripping and falls. A 2009 UK National Institute for Health and Clinical Excellence (NICE) guidance states that current evidence on safety and efficacy of FES for improving drop foot of central neurological origin is adequate to support the use of this procedure. However, the studies reviewed for this guidance were mainly on the adult stroke population.
