Sedentary Behavior in the First Year After Stroke: A Longitudinal Cohort Study With Objective Measures

摘要: Abstract Objective To quantify longitudinal changes in sedentary behavior (ie, nonexercise seated or lying behavior) after stroke to ascertain whether reducing might be a new therapeutic target. Design Longitudinal cohort study of patients with acute who were followed over 1 year. Setting Acute teaching hospital outpatient clinic, and the community discharge. Participants A convenience sample (N=96; median age, 72y, interquartile range [IQR]=64–80y; 67% men; National Institute Health Stroke Scale score=2, IQR=1–3) assessed at 1, 6, 12 months stroke. Interventions Not applicable. Main Outcome Measures measures amount pattern time spent behavior: total time, weighted bout length, fragmentation index. Results survivors highly sedentary, spending on average 81% per day median=19.9 hours (IQR=18.4–22.1h), 19.1 (17.8–20.8h), 19.3 (17.3–20.9h) months, respectively. estimated using linear mixed effects models. Covariates sex, severity (National score), physical capacity (6-minute walk distance), functional independence (Nottingham Extended Activities Daily Living Questionnaire score). Higher less associated cross-sectionally more (β=.11, SE=.05, P =.020 β=−.11, SE=.01, Conclusions remained so year independently their ability. Developing interventions reduce potential target rehabilitation.
