Functional electrical stimulation in control of motor output and movements.
In patient with damaged upper motor neurones we show the therapeutic effect of electrical stimulation (called FES) of peripheral mixed nerves on the restoration of motor activity and movements. The results of neurophysiological, kinesiological and clinical observations are presented. We discuss the possible mechanisms, especially the spinal ones, which are fundamental for such a rhythmic activity as gait. We discuss them also from the point of view of activation of proprioceptive feedback mechanisms and of achieved sensory reinforcement influencing the spinal reflex mechanisms as well as the preserved supraspinal integrated activity which contributes to the long-term FES effect. The stimulation modes, the control of stimuli in relation to the needs of individual patients (hemiplegia in adults, paraparesis, cerebral palsy in children and multiple sclerosis) as well as the motor deficit are discussed. We conclude that the electronic system used for this purpose represents a functionally active orthotic aid with therapeutic effects.
