To estimate referent values for performance on clinical mobility tests conducted amongst racially diverse adults aged 50-95 years in the Southeast US.
This is an observational study of community-dwelling older adults from diverse racial groups who participated in observational and rehabilitative studies conducted from 2011-2019.
Rehabilitation clinics around the greater metropolitan Atlanta, Georgia, region.
A total of 314 adults (N=314; 222 women). Individuals were predominantly Black (n=121) or White (n=164), with some participants from other racial groups (n=29).
Clinical and demographic data were collected at individual visits for each participant.
Four Square Step Test (FSST), timed Up and Go (TUG) test, dual TUG test, 6-minute walk test (6MWT), 30-second chair stand, and gait speed were all used as assessments in each cohort.
Performance slowly declines with increasing age, with a sharp drop in the ninth decade for preferred forward, backward, and fast gait speed; backward gait cadence; 6MWT, TUG test, dual-task TUG-Cognitive, and the 360° turn test. Declines were also seen in the eighth and ninth decades in the FSST. Among White participants, there were significant overall differences across age groups except in the assessment variable, preferred gait cadence. For Black individuals, there were significant overall differences across age groups for backward gait speed, fast gait speed, TUG-Cognitive, dual task, 6MWT, FSST, and 30-second chair stand.
These data enrich current referent values for brief, commonly used clinical tests in a diverse, older Southeast US cohort. These data include representatives of the oldest old cohort. This study will support race- and age-specific fall prevention and mobility-enhancing therapeutic application among older patients in clinical practice.
估算美国东南部 50-95 岁不同种族成年人进行临床移动测试的表现参考值。
这是一项对来自不同种族群体的社区居住老年人进行的观察性研究，他们参加了 2011-2019 年进行的观察性和康复性研究。
佐治亚州亚特兰大大都会区周边的康复诊所。
共有 314 名成年人（N=314；222 名女性）。个体主要为黑人（n=121）或白人（n=164），有些参与者来自其他种族群体（n=29）。
在每位参与者的个体就诊时收集临床和人口统计学数据。
四方步测试（FSST）、计时起立行走测试（TUG）、双 TUG 测试、6 分钟步行测试（6MWT）、30 秒椅站和步态速度均作为每个队列的评估指标。
随着年龄的增长，表现逐渐下降，首选向前、向后和快速步态速度；向后步态节奏；6MWT、TUG 测试、双任务 TUG-认知和 360°转身测试在第九个十年急剧下降。FSST 也在第八和第九个十年下降。在白人参与者中，除了首选步态节奏评估变量外，各年龄组之间存在显著的总体差异。对于黑人个体，在后向步态速度、快速步态速度、TUG-认知、双重任务、6MWT、FSST 和 30 秒椅站方面，各年龄组之间存在显著的总体差异。
这些数据丰富了当前美国东南部多元化老年人群中常用临床测试的参考值。这些数据包括最年长群体的代表。本研究将支持在临床实践中针对老年患者进行特定种族和年龄的防跌倒和增强移动治疗应用。
