Intermittent electrical stimulation of thalamus sensory nucleus effectively controlled dyskinesiae in 4 patients with Dejerine-Roussy's painful thalamic syndrome, and clonus of legs in 2 patients with post-traumatic medullary paraplegia. Results of long-term follow-up of these 6 cases, with movements controlled by implantation of a system of electrical stimulation of the thalamus sensory nucleus, are reviewed.
