Many musculoskeletal disorders are associated with over-pronated foot and decreased medial longitudinal arch (MLA) height. Foot intrinsic muscles and plantar fascia (PF) are the primary structures that support MLA. An important reason for the over-pronated foot and the reduction in the MLA height may be the morphological characteristics of the foot intrinsic muscles and PF as well as changes in their mechanical properties. The aim of the present study is to investigate the morphologic structure and mechanical properties of PF, flexor hallucis brevis (FHB), flexor digitorum brevis (FDB), and abductor hallucis (AbH) muscles in individuals with flat foot and to compare the results with those of healthy individuals.
The study included 80 participants, 40 with flat foot and 40 with normal foot posture. The foot posture of the participants was assessed using the Foot Posture Index. PF, FHB, FDB, and AbH thickness and stiffness were measured with an ultrasonography device using a linear ultrasonography probe.
Individuals with flat foot had higher AbH thickness compared to individuals with normal foot posture ( p < 0.001), whereas both groups were similar in terms of PF ( p = 0.188), FHB ( p = 0.627), and FDB ( p = 0.212) thickness. Stiffness values of the assessed tissues were similar in both groups ( p > 0.05).
AbH thickness was higher in individuals with flat foot; however, PF, FHB, and FDB thickness were similar in both groups. In addition, our results suggest that foot posture is not related to the stiffness of the assessed tissues.
许多肌肉骨骼疾病与足过度旋前和内侧纵弓（MLA）高度降低有关。足部固有肌肉和足底筋膜（PF）是支撑MLA的主要结构。足过度旋前和MLA高度降低的一个重要原因可能是足部固有肌肉和PF的形态特征及其力学性能的变化。本研究的目的是调查扁平足个体中PF、拇短屈肌（FHB）、趾短屈肌（FDB）和拇展肌（AbH）的形态结构和力学性能，并将结果与健康个体进行比较。
该研究纳入了80名参与者，其中40名扁平足患者和40名足部姿势正常者。使用足部姿势指数评估参与者的足部姿势。使用线性超声探头的超声设备测量PF、FHB、FDB和AbH的厚度和硬度。
与足部姿势正常的个体相比，扁平足个体的AbH厚度更高（p < 0.001），而两组在PF（p = 0.188）、FHB（p = 0.627）和FDB（p = 0.212）厚度方面相似。两组评估组织的硬度值相似（p > 0.05）。
扁平足个体的AbH厚度更高；然而，两组的PF、FHB和FDB厚度相似。此外，我们的结果表明足部姿势与评估组织的硬度无关。
