Development of a haemophiLia PHysiotherapy INtervention for optimum musculoskeletal health in children (DOLPHIN-II) - a randomised controlled trial
NCT ID NCT05895032
First seen Sep 10, 2026 · Last updated Sep 10, 2026
Summary
"Being able to participate in games and activities with their friends" is one of the things that matters most to boys with haemophilia. At present, there is a lack of robust evidence to determine whether muscle strengthening exercise can improve or negatively affect outcomes for young children with haemophilia. With the help of boys with haemophilia, their parents and physiotherapists the investigators have developed an exercise programme designed to increase muscle strength. Using this intervention the investigators will undertake a single-blinded, two-arm pragmatic randomised controlled trial (RCT) of a 12-week intervention verses usual care of boys with haemophilia aged 6-12 years of age.
