Abstract

This study used a within-subjects correlational design to determine the relationship between forefoot varus angle and standing rearfoot angle among individuals with above-average forefoot varus angles. Clinicians have long theorized that forefoot position is related to the standing rearfoot angle and that both may be related to pronation during gait. More recently, data suggest that the association between static forefoot and rearfoot position may be limited to those individuals with forefoot varus angles larger or smaller than average. However, little data are available on the association between static forefoot and rearfoot angles among individuals with larger than average forefoot varus angles. Twenty-three healthy participants (mean age = 27.04 +/- 6.24 years) with at least 8 degrees of forefoot varus bilaterally were recruited for this study. Goniometric measurements of forefoot varus angle and standing rearfoot angle of each foot were taken. Intraclass correlation coefficients (ICCs) were used to assess intrarater and interrater reliability of the static forefoot and rearfoot angle measurements. The Pearson product moment coefficient was used to assess the association between the forefoot and rearfoot static angles. ICCs for intrarater and interrater reliability of the forefoot and rearfoot angles were equal to or greater than 0.98 and 0.92, respectively. Forefoot varus angle was significantly correlated with standing rearfoot angle (P = .034). Among healthy individuals with larger than average forefoot varus angles, static forefoot varus and standing rearfoot valgus angles demonstrate a positive association.

摘要

本研究采用受试者内相关设计,以确定前足内翻角度高于平均水平的个体中,前足内翻角度与站立位后足角度之间的关系。长期以来,临床医生一直推测前足位置与站立位后足角度有关,且两者可能都与步态中的旋前有关。最近,有数据表明,静态前足和后足位置之间的关联可能仅限于那些前足内翻角度大于或小于平均水平的个体。然而,关于前足内翻角度大于平均水平的个体中,静态前足和后足角度之间的关联,可用数据很少。本研究招募了23名健康参与者(平均年龄 = 27.04 +/- 6.24岁),他们双侧前足内翻至少8度。对每只脚的前足内翻角度和站立位后足角度进行了角度测量。组内相关系数(ICC)用于评估静态前足和后足角度测量的评估者内和评估者间信度。皮尔逊积差系数用于评估前足和后足静态角度之间的关联。前足和后足角度的评估者内和评估者间信度的ICC分别等于或大于0.98和0.92。前足内翻角度与站立位后足角度显著相关(P = .034)。在健康个体中,前足内翻角度大于平均水平,静态前足内翻和站立位后足外翻角度呈正相关。
