“…As higher ADL levels are associated with higher physical activity levels in older adults (Amaral Gomes et al., 2021), changes in physical activity should be monitored throughout the hospitalization period. Because the ability of patients with hip fractures to stand and walk is temporarily impaired immediately after surgery (Hofbauer et al., 2021), making it difficult to measure physical activity at the time of rehabilitation admission (Pommerich et al., 2023), the relationship between physical activity at the time of rehabilitation admission and ADL at discharge is unclear. An activity monitor, such as an activity tracker using a triaxial accelerometer, can detect human body movements during the free‐living activities as well as walking (Szeto et al., 2023), allowing continuous sampling of physical activity in older adults with residual ADL disabilities after hip fracture surgery.…”
