Abstract

BACKGROUND

Many indirect clinical techniques have been developed to assess foot posture; however, there is relatively little research investigating the relationships among these techniques. We investigated the relationships among the most commonly used clinical measures of foot posture-Foot Posture Index-6 (FPI-6), navicular drop (NDP), navicular drift (NDT), and static and dynamic arch indices (SAI and DAI)-in individuals with normal foot posture and those with pronated foot.

METHODS

Sixty-three individuals with FPI-6 scores of 0 to 12 were included. A digital caliper was used to measure NDP and NDT; SAI and DAI were measured by electronic pedobarography. Assessments were applied on the dominant foot. Pearson correlation coefficients were calculated to determine the relationships among measures. Participants were classified into two groups, pronated foot (n = 33) and normal foot posture (n = 30), based on FPI-6 scores, providing a multisegmental and multiplanar assessment. The independent-samples t test was used to compare groups regarding NDP, NDT, SAI, and DAI.

RESULTS

We found a high correlation between NDP and FPI-6 (r = 0.754) and between NDP and NDT (r = 0.778) (all P < .001). A moderate correlation was found between NDT and FPI-6 (r = 0.599) and between DAI and SAI (r = 0.519) (all P < .001). A negligible correlation was found between NDP and DAI (r = 0.268; P = .033). Furthermore, NDP, NDT, and DAI values were higher in individuals with pronated foot compared with those with normal posture (P < .001 for NDP and NDT; P = .022 for DAI), whereas SAI values were not (P = .837).

CONCLUSIONS

These results suggest that there are moderate-to-strong relationships among FPI-6, NDP, and NDT and between SAI and DAI. The NDP, NDT, and DAI are suitable for the classification of foot posture based on FPI-6 scores. This study can guide clinicians and researchers to associate the foot posture measures with each other.

摘要

背景

已有许多间接的临床技术被开发出来以评估足态；然而，对于这些技术之间的关系，相关研究却很少。我们调查了在正常足态和旋前足人群中，最常用的六种临床足态测量方法（FPI-6、距骨下降低度、距骨下偏距和静态、动态足弓指数）之间的关系。

方法

共纳入 63 名 FPI-6 评分为 0 至 12 的个体。使用数字卡尺测量距骨下降低度和距骨下偏距；使用电子足底压力计测量静态、动态足弓指数。评估在优势足上进行。使用 Pearson 相关系数来确定各项测量之间的关系。根据 FPI-6 评分，将参与者分为两组，旋前足（n = 33）和正常足态（n = 30），进行多节段和多平面评估。使用独立样本 t 检验比较两组间距骨下降低度、距骨下偏距、静态、动态足弓指数的差异。

结果

我们发现距骨下降低度与 FPI-6（r = 0.754）和距骨下降低度与距骨下偏距（r = 0.778）之间具有高度相关性（均 P <.001）。距骨下偏距与 FPI-6（r = 0.599）和动态足弓指数与静态足弓指数（r = 0.519）之间具有中度相关性（均 P <.001）。距骨下降低度与动态足弓指数之间相关性较低（r = 0.268；P =.033）。此外，与正常足态相比，旋前足的距骨下降低度、距骨下偏距和动态足弓指数更高（距骨下降低度和距骨下偏距，P <.001；动态足弓指数，P =.022），而静态足弓指数则没有差异（P =.837）。
