Research of Gait Analysis Method Based on Motion Capture and LifeMOD

Abstract:

In order to systematically and comprehensively study human gait law, the method combining motion capture with software simulation was used. Firstly, Motion Analysis, a passive optical motion capture system, was selected to collect the motion information of the volunteer walking on the flat ground. Secondly, according to the experimenter’s body segmental parameters, a model was established in LifeMOD. Thirdly, the collected motion data were used to set parameters and complete the inverse dynamics simulation for obtaining the gait simulation results. Finally, after processing and analyzing of the simulation results, the gait law of the experimenter was achieved. Through comparing the analysis results with the previous research results, the method of gait analysis used in this paper was confirmed validity. The analysis results provide reference for the understanding of human gait motion and joint force, and the verification results provide the basis for using LifeMOD to conduct gait simulation and gait law research.
