A randomized, double‐blind, placebo‐controlled study of the efficacy and safety of botulinum toxin type A in upper limb spasticity in patients with stroke

Abstract

The findings of the present study suggest that treatment with BtxA in a dose of 1000 units reduces muscle tone in patients with post-stroke upper limb spasticity. This effect is sustained for at least 16 weeks. BtxA is safe in the dose used in this study. IMPORTANT NOTE: The authors wish to emphasize that the botulinum toxin preparation used in this study was Dysport (Ipsen Ltd) which has a different therapeutic equivalence from other commercially available product, Botox (Allergan Inc.).
