Biomechanical Analysis of the Musculoskeletal System of Human Foot by Using Passive Elastic Characteristics of Joint
In this study we presented kinematic and kinetic data of foot joints by using passive elastic characteristics of joints during gait. During the calculation process we used approximate equations and partial plantar pressures. The maximum angular displacements of each tarsometatarsal joint ranged from 4o to 7o and the maximum moments were from 200N⋅cm to 1500N⋅cm. It was relatively wide distribution. Foot kinematic data calculated from the approximated equations, which were represented by the correlation between moment and angular displacement, and the data from motion analysis were very similar. We found that the movements of foot joints were mainly decided by the passive characteristics of the joints when ground reaction force acts. The kinematic and kinetic analysis using approximated equations which is presented in this study can be usefully applied to describing the movements of foot joints during gait.
