In clinical practice, older people with cognitive impairment may have difficulties to understand the instructions of the Timed Up-and-Go (TUGT) test and present a bad performance. The purpose of this study was to identify differences in the TUGT performance, in an adapted version, between older adults with preserved cognition (PC), mild cognitive impairment (MCI) and Alzheimer's disease (AD), and to identify the association between the adapted TUGT performance and cognition among groups. A cross-sectional study was conducted with 118 community-dwelling older adults divided in three groups: PC ( = 40), MCI ( = 40) and AD ( = 38). The evaluation was composed by the adapted TUGT and cognitive assessment (Addenbrooke's Cognitive Examination and Frontal Assessment Battery). Only the cadence of TUGT presented significant difference between groups, specifically between AD versus MCI and PC groups. The main correlations were found between time of TUGT with fluency domain and global cognitive function, especially in the AD Group. The findings contribute to the understanding of how cognition interferes on functional mobility in older people with MCI and AD. The adapted TUGT is easy to perform in clinical practice and can be useful when assessing mobility in people with cognitive impairment.
在临床实践中，认知受损的老年人可能难以理解定时起立行走测试（TUGT）的指示，表现不佳。本研究的目的是确定在适应性版本的TUGT测试中，认知功能正常（PC）、轻度认知障碍（MCI）和阿尔茨海默病（AD）的老年人之间的表现差异，并确定适应性TUGT测试表现与各组认知之间的关联。对118名社区居住的老年人进行了一项横断面研究，分为三组：PC组（n = 40）、MCI组（n = 40）和AD组（n = 38）。评估由适应性TUGT测试和认知评估（Addenbrooke认知检查和额叶评估量表）组成。只有TUGT测试的节奏在各组之间存在显著差异，特别是在AD组与MCI组和PC组之间。主要相关性发现于TUGT测试时间与流畅性领域及整体认知功能之间，尤其是在AD组。这些发现有助于理解认知如何影响MCI和AD老年人的功能性活动能力。适应性TUGT测试在临床实践中易于实施，在评估认知受损者的活动能力时可能有用。
