47-year-old female with a 4-year history of cervical dystonia. She has been treated with botulinum toxin injections which were ineffective for her. In the expert's opinion, the success of Botulinum toxin in cervical dystonia depends on a thorough clinical assessment, exact targeting of the chosen muscles, and adequate doses of toxin injected. The expert also suggests additional or alternative treatment strategies: medical treatment by different oral drugs, or deep brain stimulation of the globus pallidus interna.
