Questions were assessed based on the NIH Study Quality Assessment Tools (https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools)
CD cannot determine, NA not applicable, 1: Yes, for the given question, 0: No, for the given question
*Independent measure (gait speed) was consistently applied within the stroke group but not between stroke and healthy older adults. Healthy older adults were asked to walk at their comfortable speed while stroke participants were asked to walk at their fast, comfortable speed
