Abstract: A force measurement system is disclosed herein. The force measurement system includes a plurality of force measurement assemblies, at least some of the plurality of force measurement assemblies configured to be independently displaceable from other ones of the plurality of force measurement assemblies such that one or more particular ones of the plurality of force measurement assemblies that are disposed underneath a subject varies over time. Each of the plurality of force measurement assemblies includes a top surface for receiving at least one portion of the body of the subject; and at least one force transducer, the at least one force transducer configured to sense one or more measured quantities and output one or more signals that are representative of forces and/or moments being applied to the top surface of the force measurement assembly by the subject.

Abstract: A force measurement system is disclosed herein. In one embodiment, the system includes a force measurement assembly configured to receive a subject; a data processing device operatively coupled to the force measurement assembly, the data processing device configured to determine a center of pressure for the subject using output forces and/or moments from the force measurement assembly; and a mobile device configured to determine one or more parameters indicative of the body sway for the subject. In this embodiment, a fall risk of the subject is assessed based upon a combination of the center of pressure and the one or more parameters indicative of the body sway determined for the subject.

Abstract: A force measurement system is disclosed herein. The force measurement system includes a force measurement assembly and a data processing device operatively coupled to the force measurement assembly. In one or more embodiments, the data processing device is configured to reference a stored global calibration matrix for the force measurement assembly, to determine a location of an applied load on the surface of the force measurement assembly using the stored global calibration matrix, to assign the applied load to one or more of a plurality of different load regions based upon the location of the applied load, and to compute one or more output forces or moments of the applied load using stored local calibration information for the one or more of the plurality of different load regions. A method of calibrating a force measurement system is also disclosed herein.
