A Randomized, Double-Blind, Placebo-Controlled, Dose-Ranging Study to Compare the Efficacy and Safety of Three Doses of Botulinum Toxin Type A (Dysport) With Placebo in Upper Limb Spasticity After Stroke

Abstract

The present study suggests that treatment with Dysport reduces muscle tone in patients with poststroke upper limb spasticity. Treatment was effective at doses of Dysport of 500, 1000, and 1500 U. The optimal dose for treatment of patients with residual voluntary movements in the upper limb appears to be 1000 U. Dysport is safe in the doses used in this study.
