Abstract : OBJECTIVE To estimate the extent to which body structure function activity and context explain driving resumption at 1 year.|DESIGN Cohort study with relationships modeled in a path analysis.|SETTING Three urban Canadian communities.|PARTICIPANTS Patients admitted to hospital with acute stroke who had driven before their stroke (n=290) who participated in a longitudinal study of stroke outcomes.|MAIN OUTCOME MEASURES Driving resumption 1 year after the initial stroke diagnosis.|RESULTS One hundred seventy-seven patients (61) returned to driving after 1 year. Direct relationships were found between measures of strength and motor activity (Stroke Impact Scale) cognition (Mini-Mental State Examination) type of stroke (hemorrhagic vs ischemic) and driving resumption at 1 year. The effects of stroke severity fatigue and sex on driving resumption were mediated through strength and motor activity shown by a model that had excellent fit (comparative fit index=.985 Tucker-Lewis Index=.952 root mean square error of approximation=.046).|CONCLUSIONS: There are multiple direct and indirect influences on driving resumption at 1 year, from the type of stroke, physical strength and motor activity, cognition, sex, and fatigue measured at 3 months. The paths outlined by this model highlight how stroke sequelae influence community mobility, as well as factors related to driving resumption that are amenable to intervention.|
