The present disclosure relates to objective evaluation of shoulder stability. An accelerometer is attached adjacent the subject's shoulder and the subject is provided with a vibrating device that is held in the hand of the subject's outstretched arm. The subject is instructed to keep his or her arm as still as possible while holding the vibrating device. Data is obtained from the accelerometer over a predetermined length of time. Using a processor, preferably wirelessly connected to the accelerometer, shoulder stability is evaluated in relation to the subject's ability to resist vibratory forces. In an embodiment, the processor evaluates shoulder stability by averaging measured g-forces obtained from the accelerometer along three axes. The average g-forces across each axis are averaged together to give an overall average. The overall average is compared with available normative values to determine the risk level.

A method for intraoperatively measuring joint contact mechanics of a patient's joint is provided. The method includes inserting a sensor between first and second bones of a joint. Then a predetermined force is applied to one of the first and second bones. Afterwards, contact mechanics such as, contact stresses, contact areas and/or forces are measured between the first and second bones in response to the applied predetermined force.

A system for displaying and collecting biomechanical measurements is provided. The system comprises: an electronic caliper including a bar, two arms slidably mounted on the bar and extending normal therefrom, a display module, and an electronic system housed in the display module and comprising a light emitting diode string of lights, a nine-axis sensor, firmware, a wireless radio, and a power source connector for electronic communication with a power source; and a remote computing device, the wireless radio in communication with the remote computing device. The electronic caliper and method of use thereof is also provided.

Systems and methods for an intuitive display of one or more anatomical objects are provided. One or more 3D medical images of one or more anatomical objects of a patient are received. Correspondences between the one or more 3D medical images and points on a 2D map representing the one or more anatomical objects are determined. The 2D map is updated with patient information extracted from the one or more 3D medical images. The updated 2D map with the determined correspondences is output.

Systems and methods for calculating a distance between a first point and a second point of an anatomical landmark are provided. An input medical image of an anatomical landmark of a patient is received. One or more probability maps predicting a first point and a second point of the anatomical landmark in the input medical image are generated using a machine learning based model. Locations of the first point and the second point in the input medical image are determined based on the one or more probability maps. A distance between the first point and the second point is calculated based on the locations. The locations of the first point and the second point in the input medical image and/or the calculated distance between the first point and the second point are output.

The present disclosure includes systems and methods for deriving certain characteristics of the patient's body related to motion from captured motion data. The characteristics may be used to compare the characteristics of the supposed injury to the characteristics of a normally functioning body part as well as the functions of an injured body part. The present disclosure provides a reliable and reproducible way to determine whether a supposed injury is a feigned or exaggerated injury or an actual injury.

A method of imaging a joint of a subject comprises administering to the subject an amount of a salt of DAB-4 linked nitroxide citrate effective to enhance an MRI image of the joint and taking an MRI image of said joint.

A method of performing an objective functional evaluation of a person's physical capacity comprises of a computer program particularly designed to amass and assess test data in accordance with a selected standard. A wide variety of evaluation protocols are incorporated to lead an operator in a step-by-step process. The method includes special testing tools, many of which have been modified to input data directly into the computer diagnostic program. The interface may be a wired or a wireless connection. The software program may use an algorithm to calculate a coefficient of variation for the multiple trials of a test, using the entered data, to providing a determination of validity of the trials. A second algorithm calculates an average result of the condition-specific protocol of tests, after which the software program correlates those average results to a database of normative standards to compute an impairment rating.
