Biomechanics analysis of human walking with load carriage.

Background: Comprehensive analysis of the inherent laws and the biomechanic principles of human walking with load carriage and building kinematics, and kinematics model of human walking with load carriage, are very meaningful for the development of devices and apparatus that are related to human walking with load carriage, such as a lower limb exoskeleton.

Objective: The gait experiment of human walking with load carriage is designed and performed in this paper.

Methods: The obtained video is marked and analyzed by using SIMI motion analytical software. The space motion coordinates at each body's mark point that is needed in the kinematics model of established human walking with load carriage is obtained. Based on inverse kinematics, a dynamic model of human walking with load carriage is established. The SPSS statistical analysis software is used for statistical processing for determining key gait parameters.

Results: The influence of load and speed on the walking gait parameters is analyzed systematically.

Conclusions: The method provides a theoretical basis for the design of an exoskeleton.
