Abstract
BACKGROUND: Early rehabilitation that includes early mobilization and increased amount of motor activity is hypothesized to be one of the most important factors contributing to the beneficial effect of comprehensive stroke unit treatment, whereas too much bed rest is hypothesized to be harmful. The purpose of the present study was to assess the association between early activity/bed rest and functional outcome 3 months later. METHODS: This was a prospective cohort study including patients with the diagnosis of stroke admitted to Trondheim University Hospital, Norway. Patients were eligible if they were less than 14 days poststroke and did not receive palliative care. Motor activity/bed rest was recorded in the acute phase using a standard method of observation, and the outcome was assessed by the modified Rankin Scale (mRS) score 3 months later. A proportional odds model was used to analyze the association between motor activity/bed rest and outcome. All analyses were adjusted for age, gender, stroke severity, time from stroke to observation, and prestroke function. RESULTS: A total of 106 patients (mean age 79.0 years, 56.6% men) were included. The odds ratio for a higher mRS score (poor outcome) was 1.04 (95% confidence interval [CI] 1.02-1.07, P = .001) as time in bed increased and .97 (95% CI .93-1.02, P = .283) as time in motor activity increased. CONCLUSIONS: This study confirms that time in bed in the early phase is associated with poor functional outcome 3 months later, indicating that too much bed rest should be avoided in the early phase after stroke.
