This study aims to systematically elucidate the integrative effects of psychological rehabilitation on the "brain-psychology-motor" triad in patients with anterior cruciate ligament (ACL) rupture. We plan to recruit 44 patients (aged 18-45) diagnosed with ACL rupture and scheduled for reconstruction surgery at Peking University Third Hospital, who will be randomly assigned to two groups. Through synchronous acquisition of questionnaire scores, motor performance data (gait, jogging, postural stability), and central neural activity (EEG), this research seeks to establish a foundation for developing neuroscience evidence-based, precision rehabilitation strategies.
Patients aged 18 to 45 years with a diagnosis of anterior cruciate ligament (ACL) rupture.
ACL rupture within 3 months prior to enrollment.
First-time ACL rupture with a scheduled reconstruction surgery at this institution.
The affected knee shows no significant redness, swelling, pain, or inflammation, with basic activities of daily living restored.
Body mass index (BMI) less than 18.5 or greater than 35 kg/m².
Age older than 45 years or younger than 18 years.
ACL rupture with a duration exceeding 3 months.
Concurrent severe injury (greater than grade I sprain) to the posterior cruciate ligament, medial collateral ligament, or lateral collateral ligament. (Note: Grade II indicates partial tear with ligament thickening, laxity, and partial fiber disruption; Grade III indicates complete rupture).
