Abstract：
The aim of the study is to evaluate the effect of minimally invasive ultrasound-guided fascial release and a foot orthoses with first metatarsal head cutout on the biomechanics of the medial longitudinal arch of the foot in cadaveric specimens.
A cross-sectional study was designed (20 body donors). Anthropometric measurements of the foot, foot posture index, and the windlass test and force were measured in different conditions: unloaded, loaded position, with foot orthoses, after a 25% plantar fascia release and after a 50% release.
For the anthropometric measurements of the foot, differences were found in foot length ( P = 0.009), arch height ( P < 0.001), and midfoot width ( P = 0.019) when comparing the unloaded versus foot orthoses condition. When foot orthoses were compared with 25% plantar fascial release, differences were found in foot length ( P = 0.014) and arch height ( P < 0.001). In the comparison with 50% plantar fascial release, differences were found in the arch height ( P < 0.001). A significant interaction between foot orthoses condition and grades was found in the arch height during the windlass test ( P = 0.021).
The results indicate that the presence of foot orthoses leads to a significant increase in arch height compared with other conditions. Furthermore, when plantar fascia release is performed, the arch does not exhibit any signs of collapse.

摘要：
目的：评估微创超声引导下筋膜松解术和切除第一跖骨头的足部矫形器对尸体标本中足内侧纵弓生物力学的影响。
方法：设计了一项横断面研究（20个身体供体）。脚的人体测量,脚的姿势指数和卷扬机测试和力在不同的条件下测量：卸载，加载位置,用足部矫形器，足底筋膜释放25%后和释放50%后。
结果：对于脚的人体测量，在脚长上发现了差异(p=0.009)，足弓高度（p<0.001）和中足宽度（p=0.019）当比较无负荷和足矫形器的条件。当足部矫形器与25%的足底筋膜松解术进行比较时，足长（p=0.014）和足弓高度（p<0.001）存在差异。与50%足底筋膜松解术相比，足弓高度存在差异(p<0.001)。在卷扬机测试期间，在足弓高度中发现了足部矫形器状况与等级之间的显着相互作用（p=0.021）。
结论：结果表明，与其他条件相比，足部矫形器的存在导致足弓高度显着增加。此外，当进行足底筋膜释放时，拱门没有任何坍塌的迹象。
