Abstract

OBJECTIVE

To examine the test-retest reliability and concurrent validity of variability of gait characteristics.

DESIGN

Cross-sectional study.

SETTING

Research laboratory.

PARTICIPANTS

Older adults (N=558) from the Cardiovascular Health Study.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Gait characteristics were measured using a 4-m computerized walkway. SD determined from the steps recorded were used as the measures of variability. Intraclass correlation coefficients (ICC) were calculated to examine test-retest reliability of a 4-m walk and two 4-m walks. To establish concurrent validity, the measures of gait variability were compared across levels of health, functional status, and physical activity using independent t tests and analysis of variances.

RESULTS

Gait variability measures from the two 4-m walks demonstrated greater test-retest reliability than those from the single 4-m walk (ICC=.22-.48 and ICC=.40-.63, respectively). Greater step length and stance time variability were associated with poorer health, functional status and physical activity (P<.05).

CONCLUSIONS

Gait variability calculated from a limited number of steps has fair to good test-retest reliability and concurrent validity. Reliability of gait variability calculated from a greater number of steps should be assessed to determine if the consistency can be improved.

摘要

目的

检验步态特征变异性的重测信度和同时效度。

设计

横断面研究。

地点

研究实验室。

参与者

心血管健康研究中的老年人（N = 558）。

干预措施

不适用。

主要观察指标

使用4米计算机化步道测量步态特征。从记录的步数中确定的标准差用作变异性的测量指标。计算组内相关系数（ICC）以检验4米步行和两次4米步行的重测信度。为建立同时效度，使用独立t检验和方差分析比较不同健康水平、功能状态和身体活动水平下的步态变异性测量指标。

结果

两次4米步行的步态变异性测量指标显示出比重测信度高于单次4米步行（ICC分别为0.22 - 0.48和0.40 - 0.63）。步长和站立时间变异性越大，与健康状况、功能状态和身体活动越差相关（P < 0.05）。

结论

从有限步数计算出的步态变异性具有尚可至良好的重测信度和同时效度。应评估从更多步数计算出的步态变异性的信度，以确定一致性是否可以提高。
