Read our Hemophilia a research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to make sure that the physical tests they use to measure how hemophilia affects movement, strength, and balance are accurate and reliable. This study will have adults with hemophilia complete a series of safe, practical physical tests twice—a few days apart—to check whether these tests give consistent results and truly measure what they're supposed to measure.
While hemophilia treatments have improved, many people still struggle with limited movement, weak muscles, poor balance, and pain from past bleeding. Doctors need reliable ways to measure these problems and track whether treatments or exercise programs actually help—but these measurement tools haven't been properly tested in adults with hemophilia yet.

You will visit the University Hospital Zurich for two testing sessions, separated by at least 2 days. During each session, you'll complete a series of safe, practical physical tests—such as standing on one leg or stepping between squares—that measure your balance, strength, and movement. The tests are designed to be low-strain and are already used safely in clinical care for adults with hemophilia.
