Schuele, S. U., R. J. Lederman, et al. Botulinum Toxin Injections in the Treatment of Musician's Dystonia. Neurology 64, no. 2 (January 2005): 341-3.
The authors present the results of eighty-four 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.
