Effect of Additional Rehabilitation After Botulinum Toxin-A on Upper Limb Activity in Chronic Stroke (original) (raw)

Background and Purpose— The aim of this trial was to determine the effect of additional upper limb rehabilitation following botulinum toxin-A for upper limb activity in chronic stroke. Methods— We conducted a multicenter phase III randomized trial with concealed allocation, blinded measurement, and intention-to-treat analysis. One hundred forty stroke survivors who were scheduled to receive botulinum toxin-A in any muscle(s) that cross the wrist because of moderate to severe spasticity after a stroke >3 months ago, who had completed formal rehabilitation and had no significant cognitive impairment. Experimental group received botulinum toxin-A plus evidence-based movement training while the control group received botulinum toxin-A plus a handout of exercises. Primary outcomes were goal attainment (Goal Attainment Scaling) and upper limb activity (Box and Block Test) at 3 months (end of intervention). Secondary outcomes were spasticity, range of motion, strength, pain, burden of c...
