结论：6周的干预导致主观变化，包括疼痛的显着减少。经过6周的干预，症状确实有所改善。此外，动态结果显示，定制的脚矫形器有一个直接的动态效果，这种影响只发生在矫形器穿在鞋。短期CFO干预导致后足运动学（最大外翻角和速度）显著降低，但未观察到膝关节运动学变化。动力学分析显示，在短期CFO干预的情况下，这些受试者在加载阶段、冲击峰值和垂直加载速率期间的踝关节内翻力矩和角冲动的最大值显着下降。在膝关节，CFO条件导致膝关节外旋力矩最大值和角冲量增加。
Conclusions: The 6-week intervention led to subjective changes, including a significant decrease in pain. An improvement in symptoms did occur with the 6-week intervention. In addition, dynamic results revealed that custom foot orthoses have an immediate effect on dynamics and that this influence occurs only when orthoses are worn in the footwear. The short-term CFO intervention led to significant decreases in rearfoot kinematics (maximum eversion angle and velocity) but no changes observed in knee kinematics. The kinetic analysis revealed that these subjects exhibited significant decreases in maxima for ankle inversion moment and angular impulse during the loading phase, impact peak, and vertical loading rate with short-term, CFO intervention. At the knee, the CFO condition led to increases in knee external rotation moment maxima and angular impulse.
