A NOVEL STUDY EXAMINING COGNITIVE-MOTOR INTERFERENCE AFTER ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION

The aim of this study is to assess the feasibility of examining cognitive motor interference (CMi) in athletes following anterior cruciate ligament reconstruction (ACLR) and return to sport through electroencephalography (EEG) and three-dimensional motion capture recordings. A 128-electrode EEG system is used to track brain wave patterns for specific biomarkers of CMi during sitting and balance tasks. An 8-camera Optitrack system is used to obtain three-dimensional kinematics during anticipated and unanticipated drop vertical jumps. Preliminary EEG N200 amplitudes (ACL: -4.99 ± 2.39; Control: -7.75 ± 5.83) and peak knee flexion (ACL: 93.29 ± 12.92°; Control: 92.87 ± 7.17°) during dual-task and unanticipated landings, respectively, demonstrate the feasibility of this study. Future work will continue to assess the effect of CMi on risk factors for secondary ACL injury
