Rehabilitation and conditioning can build resilience and reduce risk. Our recent work resulted in a prototype Optical Screening and Conditioning for Injury Resilience (OSCIR) system offering real-time, non-contact, biofeedback through field-deployable motion capture equipped with three-dimensional (3D) camera-based technology and an augmented reality (AR) viewer for tracking exercise form while detecting and alerting the users of high injury risk movement patterns. Developments were shaped by military end-users across the U.S. This study assessed the usability of our field-deployed system and validated real-time biomechanical metrics against those computed from a marker-based system.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>OSCIR includes a laptop computer, two red-green-blue-depth (RGB-D) camera arrays, and a software package including nine exercise modules that display in real-time, the user\u2019s point cloud, a skeleton with graphical biofeedback, and range of motion tracking with exercise-specific MSKI risk indicators. Biomechanical accuracy validation was conducted among n\u2009=\u200913 nonmilitary controls in compliance with Western-Copernicus Group. Usability was assessed among n\u2009=\u200933 healthy active duty servicemembers at Marine Corps Base Camp Pendleton and Explosive Ordinance Disposal Group One training facilities using the system usability survey (SUS) and structured interviews in compliance with Naval Medical Center San Diego Institutional Review Board protocol.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared to the marker-based system, OSCIR\u2019s metrics resulted in Intraclass Correlation Coefficient estimates between 0.80 and 0.98 (\u201cgood\u201d to \u201cexcellent\u201d agreement) for each metric.
