Leg blood flow study reveals clues about stroke recovery
NCT ID NCT05935670
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how blood moves through leg muscles in people who have had a stroke compared to healthy adults. Researchers used gentle leg movements and muscle contractions to measure blood flow. The goal was to learn more about why stroke survivors often have reduced exercise ability and higher risk of another stroke.
