Biomechanical modeling for foot inversion

Foot inversion was the most common injury of lower limb injury, it seriously affected the foot balance and posture control during standing and walking. The purpose of this study was to describe the rationality of biomechanical modeling for foot inversion. Plantar pressure measurements and foot roentgenogram had been reported. However, direct measurement of the internal tissues stress was difficult. A three-dimensional finite element model of foot inversion was developed to investigate the region of foot inversion injury. Compared with normal foot, the results showed that subtalar joint region was mainly weight-bearing region. Peak von Mises stress of the internal bones was transferred to the lateral longitudinal arch. The simulation in this study would provide the suggestion of therapeutic planning to foot inversion.
