Abstract:
1. A method for assessing disequilibrium and movement and balance disorders of a subject, comprising: a. providing at least one sensor selected from the group consisting of at least one force plate, at least one three dimensional camera, and at least one inertial sensor; b. positioning a subject within a sensing field of said at least one sensor; c. identifying a predetermined headshake task for said subject to perform while positioned in said sensing field, said predetermined headshake task being defined by at least one headshake parameter selected from the group consisting of angular rate of headshake and angular extent of headshake; d. identifying a predetermined motional task for said subject to perform while positioned in said sensing field, said motional task being defined by at least one motional task parameter; e. receiving at least one headshake sensor signal produced by said at least one sensor in response to an attempt by said subject to perform said predetermined headshake task and said predetermined motional task simultaneously, wherein said headshake sensor signal represents at least one headshake variance between a subject's actual performance of said predetermined headshake task and said at least one parameter of said headshake task; f. receiving at least one motional task sensor signal produced by said at least one sensor in response to an attempt by said subject to perform said predetermined motional task; wherein said motional task sensor signal represents at least one motional task variance between a subject's actual performance of said predetermined motional task and said at least one motional task parameter of said motional task; h. using said at least one headshake variance and said at least one motional task variance to assess a subject's ability to perform said predetermined motional task.
