A two-dimensional linear measurement approach for footprints, herein referred to as the "Reel Method," has been shown to be valid and reliable when used on bare footprints, however, few measurement approaches have been examined on sock-clad footprints. The present investigation examines the validity and reliability of the Reel Method as a two-dimensional linear measurement approach for use on sock-clad footprints. A walking, mid-gait footprint was collected from 30 volunteer participants using the Identicator Inkless Shoe Print Model LE 25P system. The width of the ball of the foot, calcaneal width, and distance from the most posterior aspect of the heel to the most distal aspect of the first toe were each measured and compared between and within three raters. The statistical analysis demonstrated high reliability of the Reel Method among these three raters. The data were found to be normally distributed, and measurements were consistent between and within raters. 95% Intraclass Correlation coefficients, 95% Bland-Altman Limits of Agreement and 95% Standard Error of Measurement determined high statistical agreement between and within raters, demonstrating that the Reel Method is reliable and thus valid for the linear measurement of sock-clad footprints.
一种用于足迹的二维线性测量方法，在此称为“卷轴法”，已被证明在用于裸足足迹时是有效且可靠的，然而，很少有测量方法在穿着袜子的足迹上进行过检验。本研究考察了卷轴法作为一种用于穿着袜子的足迹的二维线性测量方法的有效性和可靠性。使用Identicator无墨鞋印模型LE 25P系统从30名志愿者参与者那里收集了行走中步态的足迹。分别测量了足球宽度、跟骨宽度以及从足跟最后端到第一趾最远端的距离，并在三名评分者之间以及评分者内部进行了比较。统计分析表明卷轴法在这三名评分者之间具有高度可靠性。数据呈正态分布，评分者之间以及评分者内部的测量结果一致。95%组内相关系数、95%布兰德-奥特曼一致性界限和95%测量标准误差表明评分者之间以及评分者内部具有高度统计学一致性，这表明卷轴法可靠，因此对于穿着袜子的足迹的线性测量是有效的。
