Patent number: 9706949Abstract: A system and method for automatically quantifying mobility of a person performing a mobility diagnostic procedure. In one exemplary embodiment, the system measures a posture change test procedure with integrated inertial, location, and navigation type sensors found in a mobile computing device worn by a patient during the posture change test procedure, such as a timed-up-and-go (TUG) procedure. The measurements captured during the posture change inform a health care provider about the mobility of a patient. For example, a determination about the likelihood of the patient experiencing a fall can be assessed from measurable parameters produced from the inertial, location, and navigation-type sensors.Type: GrantFiled: February 27, 2014Date of Patent: July 18, 2017Assignee: The Board of Trustees of the University of Alabama, for and on behalf of the University of Alabama in HuntsvilleInventors: Emil Jovanov, Aleksander Milenkovic, Mladen Milosevic

Patent number: 9687168Abstract: A method and apparatus for conducting electromyography of a deep muscle non-invasively are provided. An array of suitable surface electromyography electrodes is arranged in one or more rings encircling a part of the human body in which a deep muscle being investigated is located. The potential of at least selected electrodes relative to another electrode selected from a common reference electrode (mono-polar) and other electrodes (bi-polar) in the array is recorded and the data is processed in respect of the recorded potentials of at least some of said selected electrodes in order to determine (optionally using approximations or algorithms, or both) the contribution being made by at least the deep muscle being investigated.

Patent number: 9681826Abstract: Method, device and system for measuring a degree of torsion or bending of a joint. The method comprises the steps of attaching a sensor (56) to the limbs that are joined by the joint, measuring an output signal of the sensor during torsion or bending at the joint, and a final step of relating said output signal of the sensor to a degree of torsion or bending. The sensor comprises an electrically conductive loop (51), with loop parts that run from one limb to other and back in the loop, the area of said loop at least partially covering both limbs from one limb to the other. The limbs may be limbs of the human or animal body, for instance limbs at a knee. The sensor further comprises an output unit (57) for providing an output signal that is a measure for the inductance of the loop.
