Outline of Final Research Achievements	The purpose of this study was to examine the effects of combined botulinum toxin type A (BoNT-A)and inpatient multidisciplinary (MD) rehabilitation therapy on the improvement of lower limb function in post-stroke patients.In this retrospective study, a 12-day inpatient treatment protocol was implemented on 51 post-stroke patients with spasticity. Assessments were performed on the day of admission, at discharge, and at 3 months following discharge. At the time of discharge, all of the evaluated items showed a statistically significant improvement. In subgroup analyses, the slowest walking speed group showed a significantly greater change ratio of the 10 Meter Walk Test relative to the other groups, from the time of admission to discharge.Inpatient combined therapy of simultaneous injections of BoNT-A to the upper and lower limbs and MD may improve motor function.
