Comparing 3 Different Foot Models for Ankle Joint Motion during Gait

摘要

Objective is to study different foot models and their corresponding parameters, provide references for foot segment and give the correct definition for ankle joint angle. Methods: The data were captured and analyzed by Vicon Motion System, and compute the joint angle parameters. Conclusion: The Toe Model is no suit for constructing ankle joint, MidJoint Model only for high equipped motion capture system and Phalange Model should be recommended after verification.
