First seen Nov 18, 2025 · Last updated May 21, 2026 · Updated 20 times
Summary
This study looked at why leg muscles often stay weak even after ACL surgery and rehab. Researchers tested 10 people to see if the brain unconsciously stops using the injured leg, a pattern called 'learned non-use'. They measured muscle activation, balance, and brain activity to understand this hidden cause of weakness.
