Due to blocking of pronation/dorsiflexion in flexible flat foot and restriction of these movements in using the University of California Berkeley Laboratory orthosis, provided pressures in sole by the orthosis were increased. Therefore, this article describes the evaluation of modified foot orthosis with flexible structure in the management of individuals with flexible flat foot. CASE DESCRIPTION AND METHOD: The patient was a 21-year-old male who had symptomatic flat foot. The modified foot orthosis included movable surface and the outside structure. The modified foot orthosis was evaluated by standing foot X-ray, comfort rate, electromyography of leg muscle and vertical ground reaction force during walking.
The modified foot orthosis improved the foot alignment and decreased the symptoms of flat foot with more comfort. Subtalar position by sub-maximum supination had higher position than neutral in sagittal plane. It may increase the muscle activity of peroneus longus by 7% compared to barefoot, and there was a decrease of 11% ground reaction force in mid stance.
The result of this single case evaluation only proposed the feasibility of this modified insole as the orthotic treatment in flexible flat foot. Clinical relevance The modified foot orthosis, which is mobile in the midfoot, is an orthosis for walking and standing in subjects with flexible flat foot.
由于柔性扁平足中旋前/背屈的受阻以及使用加利福尼亚大学伯克利分校实验室矫形器时这些运动的受限，矫形器在鞋底产生的压力增加。因此，本文描述了一种具有柔性结构的改良足部矫形器在柔性扁平足患者管理中的评估。病例描述与方法：患者为一名21岁有症状扁平足的男性。改良足部矫形器包括可移动表面和外部结构。通过站立位足部X线、舒适度评分、腿部肌肉肌电图以及行走时的垂直地面反作用力对改良足部矫形器进行评估。
改良足部矫形器改善了足部对线，减轻了扁平足症状，舒适度更高。次最大旋后时距下关节位置在矢状面高于中立位。与赤足相比，它可能使腓骨长肌的肌肉活动增加7%，并且在步态中期地面反作用力降低11%。
该单病例评估结果仅提出了这种改良鞋垫作为柔性扁平足矫形治疗手段的可行性。临床意义：中足可移动的改良足部矫形器是用于柔性扁平足患者行走和站立的矫形器。
