Joint torques in biped gait following changes in leg length

摘要

Extending leg length in a biped entity may improve some gait factors such as speed, worsening some others. This study is undertaken to better understand the kinetic and kinematic aspects of human gait following changes in the geometry of lower extremities. An artificial structure is built to be attached and fixed to one's leg. Using a two-sensor motion capture system practical walking data with the extended leg is collected for three different walking patterns, for which gait parameters are calculated. Particularly, joints internal forces and torques as well as the ground reaction force are targeted, compared and discussed.
