SIS=Stroke Impact Scale, MD=mean difference between first assessment and reassessment at 3 months, SRM=standardized response mean (MD divided by SD of the score difference), ADL/IADL=activities of daily living/instrumental activities of daily living. A higher SRM indicates greater sensitivity to change; SRM above 0.2, 0.5, and 0.8 indicates small, moderate, and large change, respectively.
