Data are presented for the first 50 patients with cerebral palsy who underwent chronic cerebellar stimulation for symptom alleviation. We observed significant shorter and longer term improvement in spasticity as well as athetosis, speech, and functional status. Continuing increments in improvement were noted as a function of time on stimulation. In many instances, psychometric test scores and behavior also were improved. There was one death in this series. There were no neurologic complications due to cerebellar stimulation. The results of this study warrant the judicious use of cerebellar stimulation for symptomatic and functional relief in cerebral palsy.
