Abstract

Introduction: Early detection and intervention are important to prevent dementia. Gait parameters have been recognized as a potentially easy screening tool for mild cognitive impairment (MCI); however, differences in gait parameters between cognitive healthy individuals (CHI) and MCI are small. Daily life gait change may be used to detect cognitive decline earlier. In the present study, we aimed to clarify the relationship between cognitive decline and daily life gait.

Methods: We performed 5-Cog function tests and daily life and laboratory-based gait assessments on 155 community-dwelling elderly people (75.5 ± 5.4 years old). Daily life gait was measured for 6 days using an iPod-touch with an accelerometer. Laboratory-based 10-m gait (fast pace) was measured using an electronic portable walkway.

Results: The subjects consisted of 98 CHI (63.2%) and 57 cognitive decline individuals (CDI; 36.8%). Daily life maximum gait velocity in the CDI group (113.7 [97.0-128.5] cm/s) was significantly slower than that in the CHI group (121.2 [105.8-134.3] cm/s) (p = 0.032). In the laboratory-based gait, the stride length variability in the CDI group (2.6 [1.8-4.1]) was significantly higher than that in the CHI group (1.8 [1.2-2.7]) (p < 0.001). The maximum gait velocity in daily life gait was weakly but significantly correlated with stride length variability in laboratory-based gait (ρ = -0.260, p = 0.001).

Conclusion: We found an association between cognitive decline and slower daily life gait velocity among community-dwelling elderly people.

社区老年人认知能力下降与日常生活步态之间的关系：初步报告

简介早期发现和干预对预防痴呆症非常重要。步态参数被认为是轻度认知障碍（MCI）的潜在简易筛查工具；然而，认知健康个体（CHI）和 MCI 之间的步态参数差异很小。日常生活中的步态变化可用于提早发现认知功能衰退。本研究旨在阐明认知功能衰退与日常生活步态之间的关系：方法：我们对 155 名社区老年人（75.5 ± 5.4 岁）进行了 5-Cog 功能测试以及日常生活和实验室步态评估。使用带加速度计的 iPod-touch 对日常生活步态进行了为期 6 天的测量。使用便携式电子步道对实验室10米步态（快步）进行了测量：研究对象包括 98 名智障者（63.2%）和 57 名认知功能减退者（CDI；36.8%）。CDI组的日常生活最大步速（113.7 [97.0-128.5] cm/s）明显慢于CHI组（121.2 [105.8-134.3] cm/s）（p = 0.032）。在实验室步态中，CDI 组的步长变异性（2.6 [1.8-4.1] ）明显高于 CHI 组（1.8 [1.2-2.7] ）（p < 0.001）。日常生活步态中的最大步速与实验室步态中的步长变异性呈弱相关，但具有显著相关性（ρ = -0.260，p = 0.001）：我们发现，在社区居住的老年人中，认知能力下降与日常生活步态速度减慢之间存在关联。

期刊介绍： This open access and online-only journal publishes original articles covering the entire spectrum of cognitive dysfunction such as Alzheimer’s and Parkinson’s disease, Huntington’s chorea and other neurodegenerative diseases. The journal draws from diverse related research disciplines such as psychogeriatrics, neuropsychology, clinical neurology, morphology, physiology, genetic molecular biology, pathology, biochemistry, immunology, pharmacology and pharmaceutics. Strong emphasis is placed on the publication of research findings from animal studies which are complemented by clinical and therapeutic experience to give an overall appreciation of the field. Dementia and Geriatric Cognitive Disorders Extra provides additional contents based on reviewed and accepted submissions to the main journal Dementia and Geriatric Cognitive Disorders Extra .
