Abstract:
Objective To obtain kinematic and kinetic parameters of gait initiation from young men when they are walking with constant speed. MethodDLUT4060 piezoelectric multi component force platform and DVM8820 three dimensional infrared image capture system were used to test gait initiation in 9 young men (average age was (21.3±0.5) years). ResultsThe lower limb kinematic and dynamic characteristics during gait initiation differ significantly from its subsequent steady state. The characteristic feature of gait initiation is the moving leg swinging a larger range and the stance leg performing a more powerful thrust. The center of pressure (COP) in the foot bottom shows a moving track which moved to the lateral of the moving leg firstly and then to the extension of the stance leg. ConclusionsNormal gait initiation has its unique characteristics, and the kinematics and dynamics parameters obtained in such status will be helpful for gait analysis and bio robot design.
