The Instrumented Multitask Assessment System (IMAS)

This work introduces a closed loop virtual reality platform for rehabilitating members of the armed forces after concussion or lower extremity musculoskeletal injury. Subjects perform a virtual variable-speed foot patrol designed to bring the subject's heartrate up to an operator-designated value. Relevant biometric measurements are timestamped and recorded for post-hoc analysis, including heart (ECG), brain (EEG), and movement kinematics of the hands, feet, hips, and head. The long-term goal is to use these data to guide return-to-duty decision making and to support efficient rehabilitation protocols. The platform is physically compact for ease of deployment and has been designed in a modular fashion to allow easy integration of new sensors in future designs.
