A system and method for addressing patient health through monitoring patient movement that includes, during a treatment stage, collecting kinematic data from at least one inertial measurement unit of an activity monitoring system； generating a set of biomechanical signals from the kinematic data wherein the set of biomechanical signals characterize at least one biomechanical property； updating a mobility quality score of the subject based on the set of biomechanical signals； and delivering a health assessment.
