A simple method to estimate force plate inertial components in a moving surface. Preuss, R. & Fung, J. *Journal of Biomechanics*, 37(8):1177–1180, August, 2004. Paper doi abstract bibtex Support surface perturbations are a common paradigm for the study of balance and postural control. Forces and moments acquired from force plates mounted on, or within, the moving surface will contain components resulting from the inertia of the force plate itself. These force plate inertial components must be removed in order to accurately estimate forces resulting from contact with the force plate. This is particularly important when these contact forces are to be used in further calculations, such as an inverse dynamics analysis of joint kinetics. An estimate of the FPIC can be derived using the kinematics of the moving surface and the inertial properties of the force plate. This technique allowed for a reduction of up to 85% of the peak and integrated FPIC acquired from AMTI (OR6–7) force plates during translations of 0.1 m, and surface rotations of 10°, using a ramp stimulus of 150 ms duration.
