Abstract: Wearable devices, and methods of use thereof, are provided for the measurement of isometric limb strength. In some embodiments, the device includes pivotally connected members and associated contact pads for contacting portions of a limb, where the members may be locked in position to perform isometric flexion or extension force measurements of the limb about a joint. A load cell or other force measurement sensor integrated with the device measures the force applied to one of the contact pads, either directly or indirectly. In some embodiments, the device can be reconfigured for the measurement of isometric strength for both flexion and extension.

Abstract: A method for calibrating the position and orientation of a 6-DOF sensor system mounted on a multi-segmented structure, such as the human body, is provided. The method includes a stage for mounting the sensors on the body, a stage for acquiring the 6-DOF kinematics from those sensors, a calibration stage whereby the prior stages are used to determining the sensor-to-segment transformations that are most physiologically optimal during relative skeletal motions, and a stage that to periodically monitor and correct for sensor slippage.

Abstract: A method and system for distinguishing an individual by employing anatomy and gait parameters is provided. The method includes acquiring image data of an individual, and computing a gait and/or an anatomy parameter of the individual from the image data. A match between the parameter of the individual and a particular parameter in a reference database is determined to distinguish the individual.

Abstract: A system and method for displaying kinematic and kinetic information of a subject is provided. The system includes an image input stage for acquiring image data of the subject, a transformation stage for transforming the image data into three dimensional coordinates corresponding to one or more body segments of the subject, and an output data stage for calculating the kinematic and kinetic information of the subject from the three dimensional coordinates. The system can also include a user interface for displaying the calculated kinematic and kinetic information of the subject.
