Older adults recovering from stroke engage in low levels of physical activity and spend long periods in sedentary behaviour. Sedentary behaviour during geriatric rehabilitation is still poorly understood. The aims of this study were to quantify physical activity, sedentary behaviour and accompanying patterns of change during geriatric rehabilitation.
Older adults (≥ 70 years) recovering from stroke in geriatric rehabilitation were included in this prospective cohort study. Patients wore an inertial measurement unit (IMU) on the ankle for 48 h, with data collected between 7am and 11 pm. Variables related to physical activity, sedentary behaviour and patterns of sedentary behaviour were calculated and analysed. Extracted principal components on admission and discharge were plotted in order to assess the individual degree of change.
In total, 53 patients with sufficient accelerometer wear time were included. The degree of change in physical activity and sedentary behaviour components was extremely diverse. Except for step count (P = 0.01), no significant changes were observed in any variable related to physical activity, sedentary behaviour or patterns of sedentary behaviour between admission and discharge.
Older adults recovering from stroke during geriatric rehabilitation improve their functional performance, but show little change in physical activity, sedentary behaviour or patterns of sedentary behaviour. The degree of change in physical activity and sedentary behaviour was highly diverse.
从中风康复的老年人身体活动水平较低，且长时间久坐不动。老年康复期间的久坐行为仍未得到充分了解。本研究的目的是量化老年康复期间的身体活动、久坐行为及伴随的变化模式。
本前瞻性队列研究纳入了在老年康复机构中从中风康复的老年人（≥70岁）。患者在脚踝佩戴惯性测量单元（IMU）48小时，数据收集时间为上午7点至晚上11点。计算并分析与身体活动、久坐行为及久坐行为模式相关的变量。绘制入院和出院时提取的主成分，以评估个体的变化程度。
总共纳入了53名加速度计佩戴时间充足的患者。身体活动和久坐行为成分的变化程度极为多样。除步数（P = 0.01）外，入院和出院之间，在任何与身体活动、久坐行为或久坐行为模式相关的变量中均未观察到显著变化。
在老年康复期间从中风康复的老年人功能表现有所改善，但身体活动、久坐行为或久坐行为模式变化不大。身体活动和久坐行为的变化程度高度多样。
