The U.K. NorthStar Clinical Network

The goal of this natural history study is to capture the natural history of Duchenne Muscular Dystrophy (DMD) in children and adults in the United Kingdom. Children and adults with DMD will be invited to join. The primary objective of the study is to collect longitudinal data on motor and respiratory function in DMD patients from childhood to adulthood. The secondary objectives of the study include collection of longitudinal data on other aspects of natural history on DMD, including respiratory, cardiac and endocrine complications, neurodiversity (cognitive impairment, neuro-behavioural disorders such as ADHD and autism), changes to bone density and occurrence of fractures, changes to puberty, incidence of scoliosis, unplanned hospital admissions, and quality of life. The study will also collect information on ethnicity. Participants will attend an annual or bi-annual neuromuscular clinic, and will have a series of assessments and questionnaires with the study team. These include: key medical data, physiotherapy data, respiratory assessments, Quality of Life questionnaires, and DMD questionnaires. Following assessments and questionnaire completion, data is input into the study's tailor-made National Neuromuscular Database.
