To determine the repeatability of selected temporal and spatial gait parameters in healthy children using the GAITRite electronic walkway.
Immediate test-retest design.
Community.
A sample of 57 subjects (age range, 1.3-10.9 y) participated. Subjects were stratified into 3 age groups (1.0 to <4.0 years old, 4.0 to <8.0 years old, 8.0 to <11.0 years old).
Not applicable.
Subjects completed 2 barefooted test walks at preferred gait speed. Intraclass correlation coefficient (ICC(1,1)) values, 95% confidence intervals, the Bland-Altman limits of agreement, and coefficient of variation (CV) were calculated.
Overall, ICC values ranged from .05 to .93. The amount of clinically relevant error (CV) was acceptable for all gait variables across age groups with the exception of the toe-in/out variables (CV, 46.7%-92.9%) and the heel-to-heel base of support variable (CV, 18.6%-31.5%).
Repeatability of GAITRite measurements to assess temporospatial gait parameters in typically developing children walking at self-selected paces ranged from poor to excellent. Our repeatability data for child subjects between the ages of 1.3 to 10.9 years are comparable to adult data for the same temporospatial gait parameters. We believe that the GAITRite electronic walkway is an emerging clinical tool for assessment of gait in children with and without disabilities.

57名受试者（年龄范围1.3 - 10.9岁）参与。受试者被分为3个年龄组（1.0至<4.0岁、4.0至<8.0岁、8.0至<11.0岁）。
不适用。
受试者以首选步态速度完成2次赤脚测试行走。计算组内相关系数（ICC(1,1)）值、95%置信区间、Bland-Altman一致性界限和变异系数（CV）。
总体而言，ICC值范围为0.05至0.93。除了内/外八字变量（CV，46.7% - 92.9%）和足跟对足跟支撑基底变量（CV，18.6% - 31.5%）外，各年龄组所有步态变量的临床相关误差量（CV）均可接受。
GAITRite测量评估以自选速度行走的正常发育儿童的时空步态参数的可重复性从差到优不等。我们1.3至10.9岁儿童受试者的可重复性数据与相同时空步态参数的成人数据相当。我们认为GAITRite电子步道是一种新兴的临床工具，可用于评估残疾和非残疾儿童的步态。
