This small-scale study examined the role that bare footprint collection and measurement processes have on the Reel method of measurement in forensic podiatry and its use in the Criminal Justice System. Previous research indicated that the Reel method was a valid and reliable measurement system for bare footprint analysis but various collection systems have been used to collect footprint data and both manual and digital measurement processes were utilized in forensic podiatry and other disciplines. This study contributes to the debate about collecting bare footprints; the techniques employed to quantify various Reel measurements and considered whether there was asymmetry between feet and footprints of the same person. An inductive, quantitative paradigm used the Podotrack gathering procedure for footprint collection and the subsequent dynamic footprints subjected to Adobe Photoshop techniques of calculating the Reel linear variables. Statistical analyses using paired-sample t tests were conducted to test hypotheses and compare data sets. Standard error of mean (SEM) showed variation between feet and the findings provide support for the Reel study and measurement method.
这项小规模研究考察了裸足采集和测量过程在法医足病学中对里尔测量法的作用及其在刑事司法系统中的应用。先前的研究表明，里尔方法是一种用于裸足足迹分析的有效且可靠的测量系统，但已使用了各种采集系统来收集足迹数据，并且在法医足病学和其他学科中都采用了手动和数字测量过程。本研究有助于关于裸足足迹采集的辩论；采用的量化各种里尔测量值的技术，并考虑了同一人的双脚与足迹之间是否存在不对称性。一种归纳性的定量范式采用Podotrack采集程序进行足迹采集，随后对动态足迹运用Adobe Photoshop技术计算里尔线性变量。使用配对样本t检验进行统计分析以检验假设并比较数据集。平均标准误差（SEM）显示了双脚之间的差异，研究结果为里尔研究和测量方法提供了支持。
