Movement behaviors (i.e., physical activity levels, sedentary behavior) in people with stroke are not self-contained but cluster in patterns. Recent research identified three commonly distinct movement behavior patterns in people with stroke. However, it remains unknown if movement behavior patterns remain stable and if individuals change in movement behavior pattern over time. 1) To investigate the stability of the composition of movement behavior patterns over time, and 2) determine if individuals change their movement behavior resulting in allocation to another movement behavior pattern within the first two years after discharge to home in people with a first-ever stroke. Accelerometer data of 200 people with stroke of the RISE-cohort study were analyzed. Ten movement behavior variables were compressed using Principal Componence Analysis and K-means clustering was used to identify movement behavior patterns at three weeks, six months, one year, and two years after home discharge. The stability of the components within movement behavior patterns was investigated. Frequencies of individuals’ movement behavior pattern and changes in movement behavior pattern allocation were objectified. The composition of the movement behavior patterns at discharge did not change over time. At baseline, there were 22% sedentary exercisers (active/sedentary), 45% sedentary movers (inactive/sedentary) and 33% sedentary prolongers (inactive/highly sedentary). Thirty-five percent of the stroke survivors allocated to another movement behavior pattern within the first two years, of whom 63% deteriorated to a movement behavior pattern with higher health risks. After two years there were, 19% sedentary exercisers, 42% sedentary movers, and 39% sedentary prolongers. The composition of movement behavior patterns remains stable over time. However, individuals change their movement behavior. Significantly more people allocated to a movement behavior pattern with higher health risks. The increase of people allocated to sedentary movers and sedentary prolongers is of great concern. It underlines the importance of improving or maintaining healthy movement behavior to prevent future health risks after stroke.

运动行为模式构成保持稳定，但随着时间的推移，首次中风患者的运动行为模式会发生变化

中风患者的运动行为（即身体活动水平、久坐行为）不是自成一体的，而是成群结队的。最近的研究确定了中风患者三种常见的不同运动行为模式。然而，运动行为模式是否保持稳定以及个体的运动行为模式是否会随着时间的推移而变化仍然未知。1) 调查运动行为模式组成随时间的稳定性，以及 2) 确定个体是否改变了他们的运动行为，导致在首次出院后的头两年内分配到另一种运动行为模式。中风。分析了 RISE 队列研究的 200 名卒中患者的加速度计数据。使用主成分分析压缩十个运动行为变量，并使用 K-means 聚类来识别出院后三周、六个月、一年和两年的运动行为模式。研究了运动行为模式中组件的稳定性。客观化了个体运动行为模式的频率和运动行为模式分配的变化。出院时的运动行为模式的组成不随时间而改变。在基线时，有 22% 的久坐锻炼者（活跃/久坐）、45% 的久坐运动者（不活跃/久坐）和 33% 久坐延长者（不活跃/高度久坐）。35% 的中风幸存者在头两年内分配到另一种运动行为模式，其中 63% 恶化为具有更高健康风险的运动行为模式。两年后，有 19% 的久坐锻炼者、42% 的久坐运动者和 39% 的久坐延长者。运动行为模式的组成随着时间的推移保持稳定。然而，个人会改变他们的运动行为。明显更多的人被分配到具有更高健康风险的运动行为模式中。分配给久坐运动者和久坐延长者的人数增加令人非常关注。它强调了改善或保持健康运动行为以预防中风后未来健康风险的重要性。个人改变他们的运动行为。明显更多的人被分配到具有更高健康风险的运动行为模式中。分配给久坐运动者和久坐延长者的人数增加令人非常担忧。它强调了改善或保持健康运动行为以预防中风后未来健康风险的重要性。个人改变他们的运动行为。明显更多的人被分配到具有更高健康风险的运动行为模式中。分配给久坐运动者和久坐延长者的人数增加令人非常担忧。它强调了改善或保持健康运动行为以预防中风后未来健康风险的重要性。
