Bilateral high‐frequency stimulation of the internal part of the pallidum has proven its efficacy in improving motor symptoms of dystonia. In Parkinson's disease, the stimulation of the external pallidum (GPe) can induce dyskinesias. This has never been described in dystonia. We report here a case of abnormal movements induced by the stimulation of GPe in a dystonic patient and discuss the pathophysiological mechanisms. © 2006 Movement Disorder Society
