Abstract

The functional foot orthoses have been used as an important adjunct recently in the treatment of lower extremity dysfunction related to poor mechanics and alignment. Many different types of foot orthotics have been designed clinically. Commercially, insole materials are divided into four classes. Class I materials such as Aliplast and Plastazote provide cushioning for plantar surface while class Ⅱ materials such as PPT and Spenco act as shock absorber and provide antishearing effect. The class Ⅲ materials such as silicone and polyuethane are to absorb high energy impaction and class IV such as rigid orthosis provides foot control and support.In this study, a new functional foot orthosis was designed for the flat foot with an easy making method. The orthosis was made from a cast molded in the subtalar neutral position. PPT was used as insole material and silicone as posting material. Nine subjects with 18 flat feet were treated. After 2 months of treatment, pain and walking ability had improved. All patients expressed satisfactory level of comfort and effectiveness.
