Although the connection between muscular strength and flatfoot condition is well-established, the impact of corrective exercises on these muscles remains inadequately explored. This study aimed to assess the impact of intrinsic- versus extrinsic-first corrective exercise programs on muscle morphometry and navicular drop in boys with flexible flatfoot. Twenty-five boys aged 10-12 with flexible flatfoot participated, undergoing a 12-week corrective exercise program, with a shift in focus at six weeks. Ultrasound imaging measured muscle thickness and cross-sectional area (CSA), and the navicular drop test assessed flatfoot severity. The results demonstrated a significant interaction between exercise type and sequencing on muscle morphometry. Initiating with intrinsic exercises led to sustained improvement, even after transitioning to extrinsic exercises, while extrinsic-first exercises caused deterioration in intrinsic muscle morphometry, which was recovered after transitioning to intrinsic exercises. Statistical analysis revealed significant improvements in muscle thickness and CSA over time, particularly when initiating intrinsic exercises first. The intrinsic-first group also exhibited a more pronounced reduction in navicular drop. In conclusion, initiating corrective exercises with intrinsic muscles proved more effective in improving foot muscle morphometry and reducing navicular drop in boys with flatfoot. Therefore, commencing correction with intrinsic muscle exercises is recommended before progressing to extrinsic muscle exercises.
尽管肌肉力量与扁平足状况之间的联系已得到充分证实，但矫正运动对这些肌肉的影响仍未得到充分探索。本研究旨在评估内在优先与外在优先的矫正运动方案对柔韧性扁平足男孩肌肉形态测量和舟骨下降的影响。25名年龄在10至12岁的柔韧性扁平足男孩参与了研究，他们接受了为期12周的矫正运动方案，在六周时重点发生了转变。超声成像测量肌肉厚度和横截面积（CSA），舟骨下降测试评估扁平足严重程度。结果表明，运动类型和顺序对肌肉形态测量有显著的交互作用。从内在运动开始能带来持续改善，即使在过渡到外在运动后也是如此，而外在优先运动则导致内在肌肉形态测量恶化，在过渡到内在运动后得以恢复。统计分析显示，随着时间推移，肌肉厚度和CSA有显著改善，尤其是先进行内在运动时。内在优先组的舟骨下降也有更明显的降低。总之，对于扁平足男孩，先进行内在肌肉的矫正运动在改善足部肌肉形态测量和减少舟骨下降方面被证明更有效。因此，建议在进行外在肌肉运动之前先从内在肌肉运动开始矫正。
