Introduction
I coordinate the musculoskeletal research program at the Research Unit for General Practice in Aalborg. The research programme is cross-disciplinary and includes researchers with a background in general practice, rheumatology, orthopaedic surgery, physiotherapy, sports science, health economics and human‐centered informatics. I am head of the research group OptiYouth at the Research Unit for General Practice. Our aim is to improve the health and function of adolescents through research.
