Functional electrical stimulation for a dropped foot.

The purpose of this collective review is to study the techniques, usage, methods, and clinical results of functional electrical stimulation applied to the peroneal nerve in the treatment of dropped foot. When stimulation is applied through surface electrodes, clinical reports have documented the therapeutic and orthotic benefits of functional electrical stimulation. Clinical trials are now being undertaken in which implantable electrodes are being used to stimulate the peroneal nerve in patients with dropped foot.
