Exercise as fuel: new study aims to supercharge stroke rehab
NCT ID NCT04877444
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether adding aerobic exercise (like walking or cycling) to standard physical therapy can help stroke survivors recover better. The goal is to improve arm movement, thinking, and mood. About 40 people who had a stroke at least 6 months ago will take part. Researchers hope exercise makes the brain more receptive to therapy.
