Introduction

The Duchenne Video Assessment (DVA) assesses quality of movement as an indication of Duchenne muscular dystrophy (DMD) disease severity. Caregivers video record patients performing home-based movement tasks using a mobile application, and physical therapists (PTs) rate the videos using scorecards with prespecified compensatory movement criteria. Reliability and construct validity of the DVA were tested using video and Pediatric Outcomes Data Collection Instrument (PODCI) data from patients with DMD and healthy controls from a separate study.
