Evaluation of spinal cord stimulation for postapoplectic spastic hemiplegia.

We used spinal cord stimulation (SCS) in patients with postapoplectic spastic hemiplegia in an attempt to reduce the spasticity. Three patients with spastic hemiplegia due to apoplexia were selected for the treatment. Reduction of spasticity was observed 3 to 9 days after the stimulation. Electrophysiological evaluation of the spasticity from the H reflex revealed a remarkable improvement in all three patients. The mechanism of reduction of spasticity has not yet been clarified, although a direct or indirect effect on the reticulospinal tract is thought to play a role.
