Effects of a Preoperative Cognitive-Behavioral Intervention on Kinesiophobia and Function in Anterior Cruciate Ligament Reconstruction

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.
