Hello, I would like to measure the postural control/weight shift during step initiation, especially by mean of CoP. For equipment, I am considering using a 3D motion capture system rather than a force plate.
As far as I researched, many studies have been analysied CoP using the force plate and the 3D motion capture and there is one validation study of the vertical ground reaction forces obtained from a force plate and a motion capture system. But, the motion performed in that study was squats, which is actually not completely suitable for the step initiation as step initiation is more dynamic than squats.
Could you please share your experiences about using a 3D motion capture system for assessing CoP? Or I would be also thank you for a recommendation for studies! :)
Dear Dr. Kwag,
Perhaps the paper below can assist in the assessment of the instrumentation and data needed for your project:
