While physical activity is crucial for maintaining function, health, and well-being after a stroke, there is limited understanding of how individuals post-stroke accumulate their daily activity in terms of bouts and intensities. This study aimed to characterize and contrast the daily patterns, frequency and intensity of physical activity bouts between people post stroke with different ambulation statuses compared to healthy controls.
In this cross-sectional study, physical activity bouts patterns, frequencies, and intensities were evaluated using Actigraph GT3X+ accelerometers across three groups: 17 limited community ambulators (LCA) post-stroke (walking speed: < 0.8 m/s), 22 community ambulators (CA) post-stroke (walking speed: ≥ 0.8 m/s), and 28 healthy controls.
People post stroke primarily engaged in 1-5 min bouts (LCA: 79%, CA: 76%), with less frequent engagement in 5-10 min (12-14%) and > 10 min bouts (9-10%) during the day. The LCA group engaged comparable or greater time spent in light physical activity during >5-10 and > 10 min bouts compared to CA and healthy controls, but less time in moderate to vigorous physical activity (P < .009). Both post-stroke ambulation groups were most active between 12-5 pm.
CA people post stroke exhibited patterns similar to healthy controls in physical activity bouts, whereas LCA primarily engaged in short bouts and light activity. In the context of secondary stroke prevention, encouraging LCA people post stroke to engage in frequent short bouts of moderate to vigorous physical activity or longer bouts of light physical activity might be realistic targets to improve cardiovascular health.
虽然身体活动对于中风后维持功能、健康和幸福感至关重要，但对于中风后个体如何根据活动时段和强度积累日常活动的了解有限。本研究旨在描述和对比不同行走状态的中风患者与健康对照者之间身体活动时段的日常模式、频率和强度。
在这项横断面研究中，使用Actigraph GT3X+加速度计对三组人群的身体活动时段模式、频率和强度进行了评估：17名中风后社区行走受限者（LCA）（步行速度：<0.8米/秒）、22名中风后社区行走者（CA）（步行速度：≥0.8米/秒）和28名健康对照者。
中风后患者白天主要进行1 - 5分钟的活动时段（LCA组：79%，CA组：76%），较少进行5 - 10分钟（12 - 14%）和>10分钟的活动时段（9 - 10%）。与CA组和健康对照者相比，LCA组在>5 - 10分钟和>10分钟的活动时段中进行轻度身体活动的时间相当或更长，但进行中度至剧烈身体活动的时间较少（P < 0.009）。两个中风后行走组在下午12点至5点之间最为活跃。
中风后CA组在身体活动时段表现出与健康对照者相似的模式，而LCA组主要进行短时段和轻度活动。在二级中风预防的背景下，鼓励中风后LCA组人群频繁进行短时段的中度至剧烈身体活动或较长时段的轻度身体活动，可能是改善心血管健康的现实目标。
