Gait and cognition are closely associated. Older adults with gait deficits have an increased risk of developing cognitive deficits and cognitive deficits are associated with worsened gait. Both gait and cognitive impairments are risk factors for falls in older adults.
The aims of this article are (1) to highlight the association between gait and cognition, particularly executive function, (2) to present motor cognitive dual tasking test paradigms and (3) to provide an algorithm for standardized mobility tests that can quickly and easily be performed in a private practice or on a hospital ward.
A Pubmed review of current literature on the topic as well as the personal experience and recommendations of the authors are presented. Assessments summarized: clock drawing test, stops walking when talking test, normal walking speed, timed up and go test, regular, as a dual task and imagined.
It is recommended that at least two of the presented assessments should be performed at each clinical visit in all patients age 65 years or older. If one of the assessments presented provides abnormal results, patients should be referred to a gait specialist for an in-depth quantitative gait analysis.
Assessments of functional mobility, fall risk and cognition should be an integral part of every comprehensive geriatric assessment. Quantitative gait analysis allows not only the early detection of gait deficits and fall risk, but also of cognitive deficits. Early detection allows for timely implementation of targeted interventions to improve gait and/or cognition.
步态与认知密切相关。患有步态缺陷的老年人出现认知缺陷的风险增加,而认知缺陷又与步态恶化有关。步态和认知障碍都是老年人跌倒的危险因素。
本文的目的是(1)强调步态与认知之间的关联,特别是执行功能;(2)介绍运动认知双重任务测试范式;(3)提供一种标准化移动性测试算法,该算法可在私人诊所或医院病房中快速轻松地进行。
介绍了对该主题当前文献的PubMed综述以及作者的个人经验和建议。总结的评估方法:画钟试验、边走边说测试、正常步行速度、定时起立行走测试、常规测试、双重任务测试和想象测试。
建议在每次临床就诊时,对所有65岁及以上的患者至少进行两项上述评估。如果上述评估中的一项结果异常,应将患者转诊给步态专家进行深入的定量步态分析。
功能移动性、跌倒风险和认知评估应成为每次综合老年评估的组成部分。定量步态分析不仅可以早期发现步态缺陷和跌倒风险,还可以发现认知缺陷。早期发现有助于及时实施有针对性的干预措施,以改善步态和/或认知。
