BACKGROUND/OBJECTIVES: Measuring the physical functioning of older hip fracture patients using wearables is desirable, with physical activity monitoring offering a promising approach. However, it is first important to assess physical activity in healthy older adults. This study quantifies physical functioning with physical activity parameters and assesses those parameters in community-dwelling older adults. The results are compared with the results from one case participant 2 months post-hip fracture surgery.
Twenty-four community-dwelling older adults (aged ≥ 80) participated. The acts of moving around the house, toileting, getting in/out of bed, and preparing meals was quantified by total time, time spent sitting, standing, and walking, number of transfers, and intensity of physical activity. MOX and APDM sensors measured the intensity of physical activity, with the tasks performed in a living lab while video-recorded. The case participant's total time and intensity of physical activity were measured for walking to a door and getting in/out of bed.
Preparing meals showed the longest total time and time spent standing/walking, while moving around the house and getting in/out of bed had the highest intensity of physical activity. Only getting in/out of bed required sitting. The physical activity parameters varied among participants, with very active participants completing tasks faster. The case participant had longer total times and lower intensities of physical activity two months post-surgery compared to before the fracture.
This study provides initial insights into the physical activity levels of community-dwelling older adults. It represents the beginning of more efficient and continuous monitoring of physical functioning.
背景/目的：使用可穿戴设备测量老年髋部骨折患者的身体功能是理想的，身体活动监测提供了一种有前景的方法。然而，首先评估健康老年人的身体活动很重要。本研究用身体活动参数量化身体功能，并在社区居住的老年人中评估这些参数。将结果与一名髋部骨折手术后2个月的病例参与者的结果进行比较。
24名社区居住的老年人（年龄≥80岁）参与了研究。通过总时间、坐着、站立和行走的时间、转移次数以及身体活动强度，对在房屋内走动、上厕所、上下床和准备饭菜等活动进行量化。MOX和APDM传感器测量身体活动强度，任务在生活实验室中进行，同时进行视频记录。测量了病例参与者走到门口和上下床的身体活动总时间和强度。
准备饭菜的总时间和站立/行走时间最长，而在房屋内走动和上下床的身体活动强度最高。只有上下床需要坐着。身体活动参数在参与者之间有所不同，非常活跃的参与者完成任务更快。与骨折前相比，病例参与者术后两个月的身体活动总时间更长，强度更低。
本研究为社区居住老年人的身体活动水平提供了初步见解。它代表了对身体功能进行更高效和持续监测的开端。
