New exercise trick may ease joint pain for hemophilia patients
NCT ID NCT07259356
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a training method that briefly restricts blood flow to the leg muscles can help reduce knee pain in people with hemophilia. Twelve participants will try both the real blood flow restriction and a sham version to compare effects. The goal is to see if this approach improves pain tolerance and joint health without causing harm.
