According to clinical observations, foot hyperpronation is very prevalent and may cause malalignment of the lower extremity, leading to structural and functional deficits in standing and walking. This study aimed at investigating the effect of foot hyperpronation on spine alignment in the standing position. Thirty-five healthy males with an age range of 18-30 years participated in this cross-sectional study. Evaluation was performed with two examiners in four standing positions (on the floor, and on the wedges angled at 10, 15, and 20 degrees) using a motion analysis system (Zebris). Moreover, each of the measurement methods was repeated for three short times. Paired t- test and repeated measures ANOVA test were used for statistical analysis. Significant differences were observed between all modes in the sacral angle, pelvic inclination, lumbar lordosis, and thoracic kyphosis variables (except between the first and second mode). Finally, a positive correlation was obtained for the examiners and all the variables with an increasing slope of the angle of wedge. The results of the present study revealed sacral angle, pelvic inclination, lumbar lordosis, and thoracic kyphosis were increased with an increase in bilateral foot pronation. In fact, each one of them is a compensatory phenomenon.
根据临床观察，足过度内旋非常普遍，可能导致下肢排列不齐，进而导致站立和行走时的结构和功能缺陷。本研究旨在调查足过度内旋对站立位脊柱排列的影响。35名年龄在18至30岁之间的健康男性参与了这项横断面研究。由两名检查人员使用运动分析系统（Zebris）在四个站立位（在地面上，以及在倾斜10度、15度和20度的楔形板上）进行评估。此外，每种测量方法都短时间重复三次。采用配对t检验和重复测量方差分析进行统计分析。在骶骨角、骨盆倾斜度、腰椎前凸和胸椎后凸变量的所有模式之间均观察到显著差异（第一和第二种模式之间除外）。最后，检查人员和所有变量与楔形板角度增加的斜率之间呈正相关。本研究结果显示，双侧足内旋增加时，骶骨角、骨盆倾斜度、腰椎前凸和胸椎后凸均增加。事实上，它们中的每一个都是一种代偿现象。
