Establishing Walking-related Digital Biomarkers in Rare Childhood Onset Progressive Neuromuscular Disorders
The purpose of this research is (1) to identify disease specific walking-related digital biomarkers of disease severity, and (2) monitor longitudinal changes in natural environments, for extended periods of time, in DMD and SMA.
• One of the following categories:
• Genetic confirmation of disease (DMD, SMA) or healthy control Able to walk independently at least 25 meters
• Cohort specific inclusion criteria include:
• ongoing corticosteroids therapy or initiation of corticosteroid therapy in the previous 3 months for DMD stable dose of FDA approved SMN up-regulator therapy or in an open-label extension phase of a study treatment for at least 6 months for SMA or gene replacement at enrollment for SMA or DMD participants.
