Botulinum toxin type A versus anticholinergics for cervical dystonia

• Cochrane Database Syst Rev. 2005

• We found only one trial suitable for inclusion and accordingly no meta-analysis was performed

• The available evidence suggests that BtA injections provide more objective and subjective benefit than trihexyphenidyl to patients with cervical dystonia. We could not draw any conclusions about other anticholinergic drugs.

• Future trials should explore the role of anticholinergic drugs in patients that do not get benefit with BtA.
