The purpose of this study was to determine the arch height ratio in a large cohort of subjects as well as to assess the reliability and validity of the foot measurements utilized in the study.
Eight hundred and fifty subjects, 393 women and 457 men, consented to participate in the study. The dorsal arch height, total foot length, and the truncated foot length were used to calculate two variations of the arch height ratio. In addition to determining within- and between-rater measurement reliability, radiographs were used to establish validity.
The truncated arch height ratio can be estimated using the total foot length, unless toe deformities are present in the individual being assessed. All foot measurements had high levels of intra- and inter-rater reliability and the validity of measuring the dorsal arch height while standing with equal weight on both feet was established.
This investigation provides normative values from a large cohort of healthy female and male subjects for two variations of the arch height ratio. The arch height ratio is a reliable and valid measurement that may prove useful to clinicians and researchers for the classification of foot posture.
本研究旨在确定一大群受试者的足弓高度比，并评估该研究中所采用足部测量方法的可靠性和有效性。
850名受试者（393名女性和457名男性）同意参与本研究。利用足背弓高度、足全长和截短足长来计算两种足弓高度比变体。除了确定评估者内部和评估者之间测量的可靠性外，还使用X光片来确定有效性。
除非被评估个体存在脚趾畸形，否则可使用足全长来估计截短的足弓高度比。所有足部测量在评估者内部和评估者之间均具有高度可靠性，并且确立了双脚等重站立时测量足背弓高度的有效性。
本调查提供了一大群健康女性和男性受试者两种足弓高度比变体的标准值。足弓高度比是一种可靠且有效的测量方法，可能对临床医生和研究人员进行足部姿势分类有用。
