Abstract

Background

The medial longitudinal arch (MLA) is crucial for maintaining balance and center of gravity stability during human walking. High-heeled shoes (HHS) will affect the kinematics of the MLA which further affects the overall function of the foot. However specific motion effects of HHS on MLA during walking remain unclear. Therefore, this study aimed to use dynamic biplane radiography (DBR) to explore the angle and six-degrees-of-freedom (6DOF) kinematic changes of MLA in barefoot and HHS conditions.

Methods

Fourteen healthy women without HHS experience were recruited. All subjects are required to undergo foot and ankle MRI scans for 3D modeling. Then DBR captured 2D fluorescence images of MLA throughout the stance phase during barefoot and HHS walking. MLA angle and 6DOF kinematics of the first metatarsal relative to the calcaneus were calculated using 3D-2D alignment technique in MATLAB. The MLA kinematics in 6DOF and MLA angle were compared between barefoot and HHS.

Results

During the stance phase, compared to barefoot, the MLA’s maximum lateral (9.8 ± 2.4 mm vs 7.9 ± 0.9 mm, p = 0.01), and anterior (10.0 ± 1.8 mm vs 8.1 ± 0.9 mm, p = 0.002) displacement; medial-lateral ROM(7.7 ± 2.1 mm vs 5.8 ± 1.7 mm, p = 0.004) were significantly smaller in the HHS condition. The MLA’s maximum flexion (2.4 ± 1.5° vs 7.3 ± 1.9°, p < 0.001), supination (-1.7 ± 2.3° vs 0.6 ± 1.9°, p = 0.009) were significantly larger in the HHS condition. The adduction-abduction ROM (10.2 ± 2.0° vs 7.1 ± 2.0°, p < 0.001) of the MLA was significantly smaller in the HHS condition. No significant differences (p > 0.05) were observed in peak MLA angle change and ROM after wearing HHS.

Conclusion

DBR quantifies the kinematics of the MLA during HHS walking. The results indicated that HHS decreased the MLA angle, limiting joint translation while enhancing supination and flexion angles. It may increase the risk of MLA damage during walking. These findings deepen our understanding of HHS's influence on MLA kinematics and clarify its impact on foot health.

赤足和穿高跟鞋行走时内侧纵弓的活体运动学变化。

背景：内侧纵弓（MLA）是人体行走过程中保持平衡和重心稳定的关键。高跟鞋（HHS）会影响内侧纵弓的运动学，从而进一步影响足部的整体功能。然而，高跟鞋在行走过程中对MLA的具体运动影响仍不清楚。因此，本研究旨在使用动态双平面X光摄影术（DBR）探讨赤足和HHS条件下MLA的角度和六自由度（6DOF）运动学变化：招募了 14 名没有 HHS 经验的健康女性。所有受试者均需接受足踝核磁共振成像扫描，以进行三维建模。然后，在赤足和HHS行走过程中，DBR采集了MLA在整个站立阶段的二维荧光图像。使用 MATLAB 中的 3D-2D 对齐技术计算出 MLA 角度和第一跖骨相对于小腿骨的 6DOF 运动学特性。比较了赤足行走和HHS行走的MLA运动学6DOF和MLA角度：在站立阶段，与赤足相比，HHS 条件下 MLA 的最大侧向（9.8 ± 2.4 mm vs 7.9 ± 0.9 mm，p = 0.01）和前向（10.0 ± 1.8 mm vs 8.1 ± 0.9 mm，p = 0.002）位移；内外侧 ROM（7.7 ± 2.1 mm vs 5.8 ± 1.7 mm，p = 0.004）明显较小。穿戴 HHS 后，MLA 的最大屈曲度（2.4 ± 1.5° vs 7.3 ± 1.9°，p 0.05）在 MLA 角度变化峰值和 ROM 中均有观察到：结论：DBR可量化穿着HHS行走时MLA的运动学特性。结果表明，HHS 减少了 MLA 角度，限制了关节平移，同时增强了上翻和屈曲角度。这可能会增加行走过程中 MLA 受损的风险。这些发现加深了我们对 HHS 对 MLA 运动学影响的理解，并阐明了其对足部健康的影响。
