摘 要：正 Understanding of the biomechanics of human foot and ankle complex can help in designing a better foot support. Experimental approaches are limited to interfacial pressure measurement between the foot and supporting surface and gross motion tracking of major foot joints. The measurement of internal stress/strain and individual bony movement of the foot and ankle, which is essential in enhancing knowledge on the biomechanics of the foot, is still sparse due to experimental difficulties. Computer simulation provides an efficient alternative to acquire those important clinical parameters. In this study, a 3D finite element model of the human foot and ankle, incorporating realistic geometrical properties of both bony and soft tissue components was developed to quantify the biomechanical interaction among bones, ligaments, interaction
