Existing AR code will be adapted to identify and quantify hip, knee, and ankle range of motion in both the coronal and sagittal planes. Output will be produced directly to the phone display and can also be downloadable. Both single-motion and sequential-motion (gait) measures will be captured.\n\nAim 2 will then compare the app-based MCA to traditional gold standard MCA in healthy volunteers. A dedicated human biomechanics lab with capability for MCA with reflective markers will be utilized to test both MCA methods. Patients will perform a box jump and normal walking gait, and the measurements from both the standard marker-based MCA system and the smartphone markerless MCA system will be statistically compared.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Study participants will be males and females between the ages of 18 years old to 65 years old that are healthy and without any active injuries limiting full participation, in particular no known spinal pathology, history of lower extremity surgery or significant cardiac history.
