Botulinum toxin injections in the treatment of musician's dystonia

Neurology. 2005 Jan 25;64(2):341-3. doi: 10.1212/01.WNL.0000149768.36634.92.

Abstract

The authors present the results of 84 musicians with focal task-specific dystonia treated with EMG-guided botulinum toxin injections. Treatment outcome was assessed by subjective estimation of playing before and after treatment and self-rating of treatment response. Fifty-eight (69%) of the musicians experienced improvement from the injections and 30 of 84 musicians (36%) reported long-term benefit in their performance ability.
