Brain may 'forget' to use healed leg after ACL surgery, study suggests
NCT ID NCT04837417
First seen Nov 18, 2025 · Last updated May 13, 2026 · Updated 19 times
Summary
This study looked at 10 people who had ACL knee surgery 6 to 18 months earlier. Researchers wanted to understand why leg muscle weakness often continues even after healing. They tested whether the brain unconsciously stops fully using the injured leg—a pattern called 'learned non-use'—and whether brain activity differences play a role. The goal is to find better ways to guide return to sports and design future rehab programs.
