Computer-Graphics Based Analysis of Human Foot Kinematics during the Gait


Article Preview

A computer-graphics based biomechanical model was constructed to investigate the kinematics of foot joints during the stance-phase of walking. In the model, all joints were assumed to act as monocentric, single degree of freedom hinge joints. To obtain the inputs to the model, the motion of foot segments was captured during the gait by a four-camera video system. The model fitted in an individual subject was simulated with these motion data. The ranges of motion of the first tarsometatarsal joint and the first metatarsophanlangeal joint were 8  ∼13  and -13  ∼ 48  respectively. The kinematic data of joints were similar to those of the previous studies. Our method based on the graphical computer model is considered useful for kinematic analysis of small joints including foot joints. Also, the results of this study will provide important information to the biomechanical studies which deal with human gait.
