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.
Claims18
A force measurement system, comprising:
- a force measurement assembly configured to receive a subject, the force measurement assembly including:
- 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;
- a data processing device operatively coupled to the force measurement assembly, the data processing device configured to receive the one or more signals that are representative of the forces and/or moments being applied to the top surface of the force measurement assembly by the subject, and to convert the one or more signals into output forces and/or moments, the data processing device further configured to determine a center of pressure for the subject using the 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;
- wherein 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.
