BACKGROUND: Musician's dystonia is a task-specific movement disorder that causes twisting or repetitive abnormal finger postures and movements, which tend to occur only while playing musical instruments. Such a movement disorder will probably lead to termination of the careers of affected professional musicians. Most of the currently available treatments have yet to provide consistent and satisfactory results. We present the long-term follow-up results of ventrooralthalamotomy for 15 patients with musician's dystonia. METHODS: Between October 2003 and September 2010, 15 patients with medically intractable task-specific focal hand dystonia that occurred only while playing musical instruments underwent ventrooralthalamotomy. We used Tubiana's musician's dystonia scale to evaluate the patients' pre- and postoperative neurological conditions. FINDINGS: All patients except one (93%) experienced dramatic improvement of dystonic symptoms immediately after ventrooralthalamotomy. The mean follow-up period was 30·8 months (range, 4-108 months). Noneof the patients experienced recurrence or deterioration of symptoms during the follow-up periods. INTERPRETATION: Ventrooralthalamotomy remarkably improved musician's dystoniaand the effect persisted for a long duration. ANN NEUROL 2010.
