OBJECTIVES: Spasticity is a complex disorder that causes significant disability in affected patients. We here present long-term results of botulinum toxin type A (BoNT-A) treatment in spasticity of various etiologies in the upper and lower limbs. PATIENTS AND METHODS: We evaluated long-term results of BoNT-A treatment with Dysport and Botox for up to 12 years in 137 patients with spasticity of various etiologies. The focus was laid on efficacy, dosage, safety and side effects over time in a retrospective analysis of the database of our movement disorder clinic. RESULTS: The mean clinical benefit, latency and duration of response were comparable for both products. Side effects were generally mild and comparable for the two products. We found a significant negative correlation between time from onset of spasticity to start of BoNT-A treatment and degree of improvement after treatment. CONCLUSION: Our data confirm the safety and efficacy of BoNT-A treatment of spasticity of different etiologies over a long period of time. Furthermore, the data imply that BoNT-A treatment should be started early after appearance of spasticity to obtain better treatment response.
