The purpose of this study is to evaluate the therapeutic effect of total contact insole with forefoot medial posting (TCIFMP) orthosis in patients with flexible flatfoot. The TCIFMP insole was custom- mode, made from semi-rigid plastazote and PPT. Using the gait analysis and the plantar-pressure measure systems, we investigate rearfoot motion and plantar pressure redistribution in these patients. The results of this study showed that the excessive valgus movement of the rearfoot can be reduced significantly by the TCIFMP insole in these patients. Besides, there were significant decreases in the peak pressure under the toe, lateral metatarsal, lateral foot and heel areas. Therefore, we suggested that the TCIFMP insole is an effective orthotic device for rearfoot motion control, plantar pressure reduction and re-distribution in patients with flexible flatfoot.
