Abstract Summary
Kinetic data acquired from force plates embedded in moving platforms naturally contain artifacts called inertial components; however, their removal requires knowledge of the system’s inertial properties. Our objective was to: develop a method for estimating the inertial properties and force plate inertial components for any instrumented platform; estimate the inertial properties for one specific platform; and validate the estimates using novel data. Ramp-and-hold (estimation) and random (validation) perturbations were executed to obtain the force, moment, and motion of the platform. Inertial properties were estimated by minimizing the error between measured and computed forces and moments. Estimates were validated by calculating the coefficient of determination between the measured and computed forces or moments. We found excellent agreement between measured and computed force plate signals. Our method can be used for removing inertial components from force plate signals, yielding reliable estimates of ground reactions in dynamic biomechanical research.
