View Full Version : Inverse dynamic data from an unstable surface on a GRF platform?

Does anyone have a suggestion for how to acquire data for inverse dynamics, if the foot forces are going through an unstable surface before hitting the GRF platform?

I'm interested in putting a subject on the flat surface of a bosu ball (half of a thera-ball with a solid surface http://www.bosu.com/ ) to do single leg squats. A GRF plate beneath the ball would be able to collect all the forces, and the center of pressure. My concern is that the motion and height of the bosu ball will require too many assumptions for accurate inverse dynamics data.

Any thoughts or articles you can direct me to for help?
