Mechanical Analysis of Foot Plantar Fascia During Normal Walking Condition

摘要：

　　Foot plantar fascia is an important foot tissue in stabilizing the longitudinal arch of human foot.Direct measurement to monitor the mechanical situation of plantar fascia at human locomotion is difficult.The purpose of this study was to construct a three-dimensional finite element model of the foot to calculate the internal stress/strain value of plantar fascia during different stage of gait.The simulated stress distribution of plantar fascia was the lowest at heelstrike,which concentrated on the medial side of calcaneal tubercle.The peak stress of plantar fascia was appeared at push-off,and the value is more than 5 times of the heel-strike position.Current FE model was able to explore the plantar fascia tension trend at the main sub-phases of foot.More detailed fascia model and intrinsic muscle forces could be developed in the further study.
