Abstract
A force sensing device for use in analyzing the movement of a person or animal. The device includes a base and a platform supported on the base by ball casters. The platform includes first and second plates with pneumatic tubing positioned between the plates. Forces on the platform result in compression of the pneumatic tubing, and the corresponding pressure changes in the pneumatic tubing are measured by associated pressure transducers. The device includes side rails which extend upwardly from the base and surround the platform. The side rails each include first and second plates with pneumatic tubing positioned between the plates. Side-to-side movement of the platform against the side rails results in compression of the pneumatic tubing in the side rails, and associated pressure transducers measure the corresponding pressure changes. The measurements from the pressure transducers are converted into force measurements and used to analyze the movement of the person or animal.
