Riluzole therapy in cervical dystonia

Authors


Abstract

We conducted a 6-week open-label pilot study with blinded video rating of riluzole (50 mg twice a day) in six patients with cervical dystonia (CD) refractory to botulinum toxin A and oral pharmacological treatment. The Tsui rating scale served as primary efficacy measure and improved significantly under riluzole (P = 0.002). In three of six patients, the Tsui score improved by more than 30% with a greater 50% reduction in the head tremor/jerk subscore of the Tsui scale. These data suggest that riluzole may be helpful in a subgroup of patients with disabling CD refractory to other therapies. © 2001 Movement Disorder Society.
