Researchers have developed xAARA, a novel engine designed to assist clinicians in assessing stroke rehabilitation progress. Unlike existing methods that compress rich movement data into single scores or provide opaque automated assessments, xAARA leverages multi-view video to provide ARAT assessments with calibrated uncertainty and detailed explanations. The system composes 692 multimodal models using a Dynamic Bayesian Network and adheres to clinical validity rules, deferring low-confidence cases. In trials with 105 stroke survivors, xAARA demonstrated high accuracy in task and movement-phase assessments, significantly reducing predictive uncertainty and receiving validation from independent clinicians who expressed willingness to adopt the system.
