I research physiotherapist-led, non-surgical treatment approaches for femoroacetabular impingement syndrome (FAIS), hip-related pain, and other musculoskeletal disorders. My PhD project includes a multicentre randomised controlled trial, registry-based epidemiology, and health-economic analyses. I investigate which first-line treatment is most effective and cost-effective compared to current practice. I also contribute to other musculoskeletal research projects, including randomised controlled trials, registry-based studies, and systematic reviews.

Contributing to PhD-level teaching in basic biostatistics with focus on study design, statistical analysis, and interpretation of health science data. The course is led by Professor Erik Parner, Aarhus University, and targets PhD students and researchers within the health sciences. Since the autumn semester of 2024, Frederik Foldager has contributed to Basic Biostatistics Part 1 (3.2 ECTS) and Part 2 (4.7 ECTS).

Academic supervision of graduate students enrolled in the Master of Health Science programme at Aarhus University. The supervision has included project development, study design, scientific methodology, data analysis, and academic communication within health science research. Frederik Foldager has served as academic supervisor for 10 students during the 1st and 2nd semesters and 1 student during the 3rd and 4th semesters.

I lead The Better Hip Trial, which investigates the clinical effectiveness and cost-effectiveness of a six-month physiotherapist-guided exercise intervention compared with usual care for patients with femoroacetabular impingement syndrome (FAIS). The project is conducted in collaboration with Aarhus University Hospital, Aalborg University Hospital, Horsens Regional Hospital, Hvidovre Hospital, and the La Trobe Sport and Exercise Medicine Research Centre in Melbourne, Australia. The health-economic evaluation is conducted in collaboration with Maurits van Tulder and Hanneke van Dongen from Vrije Universiteit Amsterdam.

In addition, I contribute to several randomised controlled trials within musculoskeletal research. The Strong-Hip Trial investigates the effect of an extended exercise intervention compared with usual care following revision total hip arthroplasty. The Hip Booster Trial compares the effects of two physiotherapist-guided exercise interventions for patients with hip osteoarthritis. The EduEx Trial investigates the effect of exercise combined with patient education compared with patient education alone for patients with hip osteoarthritis. The BEAN Trial investigates the effect of early versus delayed blood flow restriction training following Achilles tendon rupture.
