Abstract:
The authors report the effect of chronic stimulation of the ventrointermediate (Vim) thalamus for treatment of dystonic paroxysmal nonkinesigenic dyskinesias (PNKD). A 37-year-old patient had a 4-year history of severe and painful PNKD of the right arm. Chronic stimulation through a stereotactically implanted monopolar electrode in the left Vim resulted in a decrease of the frequency, duration, and intensity of the dystonic paroxysmal movement disorder. The benefit of stimulation has been maintained over 4 years of follow-up.
