Study Summary

Objective: To determine if the calcium channel blockers, amlodipine can augment the effect of botulinum toxin injections in the treatment of focal dystonia. Study Population: 20 patients with cervical dystonia Design: Double-bind, placebo-controlled clinical trail. Outcome measures: For patients: dystonia rating scales (Twistrs, Fahn-Marsden dystonia scale, NINDS subjective patient rating scale), and hand grip strength. For healthy volunteers: Amplitude of EDB MEP.

Primary Outcome

Rating scale assessing sum of severity of dystonia, disability score and pain scale. Ordinal scale ranging from 0 (least severe) to 30 (maximally severe). Score is maximal response TWSTR rating minus baseline rating.
