Analysis on the gait of lower limbs in different walking speed

Abstract

In order to find out the change of loading on lower limbs associated with different walking speeds, 15 young males and 15 females were tested in different walking speeds with barefoot. The kinematics and kinetic dates were collected by Coda motion capture system, ATMI force platform. Knee forces (KF) were calculated by anybody software. The results shows that with increase of walking speed, the heel reaction force in sagittal and vertical axis increases, which results in a weaker stability. The forces on the knee in three directions becomes significantly higher when walking at a faster speed, which results in an increase in the load and the risk of knee cartilage and ligament injury was increased too.
