244--257 (1981)Zusammenfassung
This report presents observations in 160 patients undergoing chronic spinal cord stimulation for various disorders of the motor system and compares the results obtained using older conventional two-electrode bipolar stimulation with a newly developed four-electrode multiple level system. Improvement was noted in 84\% of the 75 patients with cerebral palsy, 67\% of the 42 patients with dystonia, 62\% of the 21 patients with torticollis and 73\% of the 22 patients with post-traumatic neurologic loss. Significant improvements were noted when comparing the two-electrode system with the new multiple level electrode. Marked to moderately improved patients increased from 57 to 84\% in cerebral palsy, from 44 to 82\% in dystonia, from 53 to 75\% in torticollis and from 53 to 80\% in dystonia, from 53 to 75\% in torticollis and from 53 to 80\% in posttraumatic neurologic conditions. There was a corresponding marked drop in unimproved patients in each condition.
