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).
Parallel
Cognitive-Behavioral Intervention
Other interventionThis is a preoperative psychological intervention that uniquely combines a single in-person session (featuring guided practice of normal movement without assistive devices) with weekly phone support for 3-4 weeks, specifically designed to reduce kinesiophobia before anterior cruciate ligament reconstruction surgery.
Control group
Other interventionThis group receives standard preoperative care only (no psychological intervention). They undergo identical outcome assessments at the same time points as the intervention group.
The Tampa Scale for Kinesiophobia (TSK)-11
The Tampa Scale for Kinesiophobia (TSK) is a validated, patient-reported questionnaire designed to assess the fear of movement and (re)injury. The 11-item version (TSK-11) used in this study is a widely adopted shortened form with robust psychometric properties. It consists of 11 statements (e.g., "I'm afraid that I might injure myself if I exercise") to which participants indicate their level of agreement on a 4-point Likert scale ranging from 1 ("strongly disagree") to 4 ("strongly agree"). The total score is calculated by summing the responses to all 11 items, resulting in a possible score range from 11 to 44. A higher total score indicates a greater degree of kinesiophobia.
Electroencephalography
Electroencephalography is a non-invasive neurophysiological technique used to record and measure the brain's spontaneous electrical activity from the scalp.
