Step test could help track fitness in hemophilia patients
NCT ID NCT07425327
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the two-minute step test is a reliable way to measure aerobic endurance in people with hemophilia. Researchers will test 35 people aged 6–18 with hemophilia A or B, comparing the step test with other measures like walking tests and balance assessments. The goal is to see if this simple test can be used in clinics to track physical fitness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could give doctors a simple, reliable test to check aerobic fitness in people with hemophilia, improving how they monitor health.
- What could go wrong
- This is a small, early-stage study (35 people) that only checks if the test is valid and reliable—it does not test any treatment or health outcome.
