  • Patent number: 8800366
    Abstract: This invention relates to a robotic exoskeleton comprising mechanical linkages that couple to one or more selected joints of a limb of a subject. The robotic exoskeleton may be provided with means for obtaining data respecting angular position, torque, and/or acceleration of at least one of the joints or the links of the mechanical linkages, and may be used for assessing, studying, diagnosing a deficit, and/or treating an impairment in sensorimotor function of a limb of a subject.

  • Patent number: 8740794
    Abstract: A method and apparatus is provided for diagnosing, assessing, or detecting brain injury and/or a neurological disorder of a subject. Objects are presented to the subject over a range of locations within the subject's workspace such that the subject can interact with at least some of the presented objects using either the right or left limb, or portion thereof, of a pair of limbs. Position data and/or motion data and/or kinetic data of the left and right limbs or portions thereof with respect to a presented object are obtained, and a data set is acquired for a plurality of presented objects. The acquired data set provides information about brain injury and/or a neurological disorder in the subject.

  • Patent number: 8730266
    Abstract: This invention relates to gaze tracking methods and systems integrated with virtual reality (VR) or augmented reality (AR). A system may include one or more cameras for capturing images of a subject's eyes, a display device for displaying a VR or AR image, a first reflecting surface associated with the display device for at least partially reflecting light from the eyes to the one or more cameras and for transmitting the VR or AR image; and a second reflecting surface for at least partially reflecting light from the eyes to the one or more cameras and for receiving the VR or AR image and rendering the VR or AR image to the subject as at least one component of a VR or AR environment. The methods and systems described herein may be used in research, medical, industrial, aerospace, and entertainment applications.

  • Patent number: 8277396
    Abstract: This invention relates to a method and apparatus for assessing proprioception in a subject. One embodiment of an apparatus of the invention comprises two articulating members attachable to a pair of limbs of a subject, and provides data relating to geometry and/or location and/or motion of each limb in 2- or 3-dimensional space. The apparatus may include means for monitoring gaze direction. The apparatus may comprise a robotic linkage. One embodiment of the method comprises obtaining data relating to the geometry and/or location and/or motion of the limbs, or portions thereof, of a subject as the subject performs a matching task. Another embodiment comprises obtaining data relating to the location of a limb of a subject, together with data relating to gaze direction as the subject looks toward the perceived location of limb.

  • Patent number: 6155993
    Abstract: An instrument for measuring kinetic and kinematic variables of multijoint motor tasks comprises a linkage having four links connected at four joints, each joint having articulation about an axis, the four axes of articulation being substantially parallel, limb coupling means for coupling a limb to the linkage, the limb coupling means maintaining alignment of centers of rotation of two joints of the limb with centers of rotation of two joints of the linkage, means for providing a load to at least one of the two joints of the linkage, means for obtaining data respecting angular position of at least one of the joints of the linkage. In an alternative embodiment, the linkage has only two links. The invention also provides methods for detecting, monitoring, and/or treating neural and/or muscular problems associated with impaired movement of limbs.
