This study aimed to evaluate the relationship between improvement in activities of daily living (ADL) and cognitive status during rehabilitation and assess factors associated with ADL improvement among older patients undergoing rehabilitation after hip fractures. This retrospective cohort study comprised 306 patients aged ≥80 years who underwent hip fracture rehabilitation. The functional independence measure gain during rehabilitation was significantly lower in the group with abnormal cognition than in the group with normal cognition. Mini-Mental State Examination, Charlson Comorbidity Index, daily duration of rehabilitation, and length of hospitalization for rehabilitation were independent factors associated with functional independence measure gain during rehabilitation in the multivariate regression analysis. Although older patients with cognitive impairment had lower ADL improvements during hip fracture rehabilitation, such patients may be able to improve their ADL by undergoing intensive and long rehabilitation programs. They should not refrain from such rehabilitation programs due to older age, fracture, and cognitive impairment.

本研究旨在评估康复期间日常生活活动能力 (ADL) 的改善与认知状态之间的关系，并评估髋部骨折后接受康复治疗的老年患者 ADL 改善的相关因素。这项回顾性队列研究包括 306 名年龄≥80 岁并接受髋部骨折康复治疗的患者。与认知正常组相比，认知异常组在康复期间获得的功能独立性测量增益显着较低。在多变量回归分析中，简易精神状态检查、查尔森合并症指数、每日康复持续时间和康复住院时间是与康复期间功能独立性测量增益相关的独立因素。尽管认知障碍的老年患者在髋部骨折康复期间的 ADL 改善较低，但这些患者可能能够通过强化和长期的康复计划来改善他们的 ADL。他们不应因年老、骨折和认知障碍而回避此类康复计划。
