Abstract: Systems and methods of the present disclosure may include initializing a first plurality of inertial measurement units (IMUs) and a second plurality of IMUs, and attaching the first plurality of IMUs to a first segment of a subject and the second plurality of IMUs to a second segment of the subject. Such a method may also include obtaining data from the first plurality of IMUs and the second plurality of IMUs as the subject performs a motion, and determining an absolute position of the first segment and the second segment based on the data.

Abstract: A device for assessing hip joint conditions comprises a support structure including a first platform area and a second platform area spaced from each other. The device includes a first footrest rotationally coupled to the first platform, a second footrest rotationally coupled to the second platform, a first recording device coupled to the first footrest and adapted to record the angular movement of the first footrest, and a second recording device coupled to the second footrest and adapted to record the angular movement of the second footrest.
