Abstract:
1. A dual force plate system having two independent measurement surfaces, the dual force plate system comprising: a first plate component having a first measurement surface for receiving a first portion of a body of a subject, a first opposed surface that is disposed generally opposite to the first measurement surface, and a plurality of lateral surfaces that extend between the first measurement surface and the first opposed surface; a second plate component having a second measurement surface for receiving a second portion of the body of the subject, a second opposed surface that is disposed generally opposite to the second measurement surface, and a plurality of lateral surfaces that extend between the second measurement surface and the second opposed surface; a first force transducer element operatively coupled to either the first opposed surface of the first plate component or to one of the lateral surfaces of the first plate component, the first force transducer element configured to output at least one first quantity that is representative of a shear force being applied to the first measurement surface; a second force transducer element operatively coupled to either the second opposed surface of the second plate component or to one of the lateral surfaces of the second plate component, the second force transducer element configured to output at least one second quantity that is representative of a shear force being applied to the second measurement surface; and a third force transducer element operatively coupled to either the first opposed surface of the first plate component and the second opposed surface of the second plate component, or to one of the lateral surfaces of the first plate component and one of lateral surfaces of second plate component, the third force transducer element configured to output at least one third quantity that is representative of a load being transferred between the first plate component and the second plate component.
