force plate

a device for measuring the force between a body or object and the ground (the ground reaction force). Often constructed from strain gauges or piezo-electric transducers. Also known as a force platform.

ground reaction force

; GRF force offered by support surface, equalling and opposing force due to body mass passing through the foot to the ground surface; GRF is resolved into vertical (counteracting body weight) and horizontal (leading to forward movement) components

This method adjusts initial velocity and stiffness until a best fit is found between predicted and calculated vertical GRF.
In the case of forward fall recovery resulting from a trip, the individual steps forward and the foot of the swing leg is placed anterior to the body, which causes a backward- and upward-directed GRF [17].
