To measure and compare physical activity profiles and sedentary time between community dwelling stroke survivors and healthy volunteers.
Twenty-two stroke survivors (10 men, age 55.3 ± 9.9 years; 4.2 ± 4.0 years since their stroke) were recruited from local stroke support groups, and 22 controls were matched for sex, age and body mass index (BMI). All participants wore an ActivPAL™ physical activity monitor for seven days and from these data activity profiles, including the number of steps per day, time spent sedentary and time in different cadence bands, were recorded.
Stroke survivors took significantly fewer steps per day than the controls (4035 ± 2830 steps/day versus 8394 ± 2941 steps/day, p < 0.001) and sedentary time (including sleep time) was significantly higher for stroke participants compared to the controls (20.4 ± 2.7 h versus 17.5 ± 3.8 h, p < 0.001). People with stroke spent a significantly higher proportion of their walking time in lower self-selected cadences compared to the controls.
Community dwelling stroke survivors spent more time sedentary, took fewer steps and walked at a slower self-selected cadence. Interventions to increase walking and reduce sedentary time following stroke are required which may have the added benefit of reducing cardiovascular risk in this group. Implications for Rehabilitation Stroke survivors are predisposed to reduced physical activity and increased cardiovascular risk. This study showed that community dwelling stroke survivors spent more time sedentary, took fewer steps and walked at a slower self-selected cadence. Interventions are required which focus on reducing sedentary time as well as increasing step counts in people following stroke.
测量并比较社区居住的中风幸存者与健康志愿者的身体活动状况及久坐时间。
从当地中风支持小组招募了22名中风幸存者（10名男性，年龄55.3±9.9岁；中风后4.2±4.0年），并匹配了22名性别、年龄和体重指数（BMI）相近的对照者。所有参与者佩戴ActivPAL™身体活动监测仪七天，记录这些数据中的活动状况，包括每日步数、久坐时间以及在不同步频区间的时间。
中风幸存者每天的步数明显少于对照者（4035±2830步/天对8394±2941步/天，p<0.001），中风参与者的久坐时间（包括睡眠时间）明显高于对照者（20.4±2.7小时对17.5±3.8小时，p<0.001）。与对照者相比，中风患者在较低的自我选择步频下行走的时间占比明显更高。
社区居住的中风幸存者久坐时间更长，步数更少，自我选择的步频更慢。中风后需要采取干预措施来增加行走并减少久坐时间，这可能会降低该群体的心血管风险。康复意义 中风幸存者易出现身体活动减少和心血管风险增加的情况。本研究表明，社区居住的中风幸存者久坐时间更长，步数更少，自我选择的步频更慢。需要采取干预措施，重点是减少中风患者的久坐时间并增加步数。
