  • Patent number: 6800062
    Abstract: A comprehensive vertigo management system and methodology is provided which employs a spatial maneuvering device, preferably under computer control, to orient a subject selectively differently in space, thus to create vestibular activity which is directly related to spatial motion (including acceleration) and/or orientation. Data is collected relating to such orientation and activity, along with certain subject-introduced reaction data in certain instances and video-camera data, and fed to a computer which cooperates in presenting an intuitive visual and pictorial correlation that enables physician diagnosis, treatment and rehabilitation regarding elements of dysfunction of the subject's vestibular system.
