About

Introduction/Objectives: In this observational study, we assessed the benefit following an injection of 200 international units (IU) of incobotulinum toxinA in patients with multiple sclerosis (MS) with spasticity of the triceps surae (TS) at 6 weeks (peak efficacy of toxin) and at 3 months (cancellation of efficacy).

Methods: This study enrolled all MS patients willing to participate with Expanded Disability Status Scale (EDSS) scores of less than 6, who required toxin for management of focal spasticity of the TS. Treatment consisted of 200 IU of incobotulinum toxinA injected into the TS. Outcome measures were assessed before injection, at 6 weeks and 3 months post-injection, using the Goal Attainment Scale (GAS), Twelve Item MS Walking (MSWS-12) Scale, Timed Up and Go (TUG) Test, 6 Minute Walk Test (6MWT). Spatiotemporal gait data was obtained by GAITRite.
