About

Inverted orthosis is a type of rigid foot orthosis that was designed to aid in controlling high degrees of foot pronation. It is essential to administer patients foot orthoses with different inverted angles, with higher angles prescribed when greater reduction of foot pronation is indicated. However, there is shortage of clinical knowledge regarding the inverted angle in terms of biomechanical changes. The aim of this study is to investigate the effect of different inverted angles of foot orthoses on the walking kinematics in females with flexible flatfeet.
