Brain training for knees: new study explores how exercise rewires the mind after ACL injury
NCT ID NCT07243860
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how a structured exercise program called neuromuscular training helps people recover knee function after an ACL tear and surgery. Researchers will measure muscle strength, movement patterns, and brain activity in 50 participants. The goal is to understand how the brain changes during rehabilitation, which could lead to better recovery strategies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- neuromuscular training (supervised exercise program)
- What this could lead to
- If successful, this could lead to better rehabilitation programs that improve knee recovery and help understand how the brain adapts after ACL injury.
- What could go wrong
- This is a small, early-stage study with only 50 participants, so results may not apply to everyone. It focuses on understanding mechanisms rather than proving a new treatment works.

Inclusion Criteria: 1. Body Mass Index (BMI) ≥18.5 kg/m² and \<35 kg/m²; 2. Diagnosed with first-time, unilateral, isolated anterior cruciate ligament (ACL) rupture ; 3. No or only mild concomitant injuries to the posterior cruciate ligament, medial collateral ligament, or lateral collateral ligament; 4. Voluntarily participated in the study and provided written informed consent . Exclusion Criteria: 1. Patients with ACL rupture for more than 6 months; 2. Combined severe injuries (Grade II or higher) to the posterior cruciate ligament, medial collateral ligament, or lateral collateral ligament(Grading Note: Grade II indicates partial tear with ligament thickening, tortuosity, and fiber disruption; Grade III indicates complete rupture);OR combined severe meniscal tears ; 3. History of prior knee surgery (e.g., meniscal repair, ligament reconstruction, arthroplasty, arthroscopic debridement); 4. Presence of other knee pathologies: knee osteoarthritis, tumors, rheumatoid arthritis, tuberculosis, infectious or inflammatory diseases, fractures, dislocations, or other skeletal injuries; 5. Severe cardiac, pulmonary, cerebral, hepatic, or renal dysfunction; OR visual/cognitive impairments.
