A Multicenter Cohort Study of Duchenne and Becker Muscular Dystrophy in Western Chinese Children

This is a prospective, multicenter, longitudinal observational cohort study aimed at understanding the progression of Duchenne Muscular Dystrophy (DMD). The primary objective is to identify and integrate key biomarkers from multiple sources-including motor function assessments, body composition (muscle and fat distribution), clinical laboratory tests, and cardiopulmonary imaging-to delineate comprehensive disease trajectories. By analyzing how these factors change over time in a large cohort, the study seeks to develop a robust model that can identify patterns of disease progression. The ultimate goal is to generate evidence that may aid in forecasting individual patient outcomes and inform the future development of personalized rehabilitation and therapeutic strategies.
