Understanding how both active and sedentary time is accumulated in people after stroke may help to better target interventions to reduce stroke recurrence. This study aimed to determine the difference between stroke and healthy controls in (a) time spent in sedentary and active behaviour, (b) frequency of short and long active and sedentary bouts and (c) time spent in short and long active and sedentary bouts.
Analysis of secondary outcomes from a cross-sectional study. Participants were 42 community-dwelling people after stroke and 21 age-matched healthy controls. An activity monitor was used to collect free-living active and sedentary behaviour. Total active (standing and walking) and sedentary (lying, reclining and sitting) time was calculated in minutes per day. Bouts were categorized as short (<5 min, 5-15 min, 15-30 min) or long (>30 min). The frequency of and time spent in each bout were calculated.
Relative to wear time, the stroke group spent 10% (95% confidence interval [CI] 3 to 17) more time in sedentary behaviour and had fewer long active bouts than the healthy controls. The stroke group spent 7% (95% CI 1-13) less time in long active bouts and 11% (95% CI 2-20) more time in long sedentary bouts than the healthy controls.
Community-dwelling people after stroke spent less time in active behaviour and accumulated more sedentary time in bouts longer than 30 min compared with healthy controls. Increasing active time and breaking up long sedentary time warrants investigation in people after stroke.
了解脑卒中患者主动和被动时间的积累方式，可能有助于更有针对性地开展干预措施，以降低脑卒中复发率。本研究旨在确定脑卒中患者与健康对照组在以下方面的差异：（a）久坐和活动行为的时间分配；（b）短时间和长时间活跃及久坐行为的频率；（c）短时间和长时间活跃及久坐行为的时间。
对一项横断面研究的次要结局进行分析。研究对象为 42 名居住在社区的脑卒中患者和 21 名年龄匹配的健康对照组。使用活动监测仪收集自由活动时的活跃和久坐行为数据。以分钟为单位计算每天的总活跃（站立和行走）和久坐（躺卧、斜倚和坐立）时间。将时间划分为短时间（<5 分钟、5-15 分钟、15-30 分钟）和长时间（>30 分钟）。计算每个时间区间的出现频率和时间分配。
与佩戴时间相比，脑卒中患者的久坐行为时间多 10%（95%置信区间 [CI]：3-17），长时间活跃行为次数少。与健康对照组相比，脑卒中患者的长时间活跃行为时间少 7%（95% CI：1-13），长时间久坐行为时间多 11%（95% CI：2-20）。
与健康对照组相比，居住在社区的脑卒中患者主动行为时间较少，且长时间久坐行为时间较多。增加活跃时间和减少长时间久坐时间值得脑卒中患者进一步研究。
