Anterior cruciate ligament (ACL) re-injury rates are high in collegiate athletes, and double-leg squats are commonly used following ACL reconstruction (ACLR). The purpose was to quantify the correlations between the medial-lateral shoulder/hip kinematics and bilateral kinetic asymmetries during double-leg squats in collegiate athletes at two assessments. Seventeen collegiate athletes performed three double-leg squats 0-6 months and/or 6-12 months following ACLR. Medial-lateral shoulder/hip positions and bending angles were calculated. Medial-lateral hip positions were significant and strongly correlated with ground reaction force and knee moment asymmetries. A commercially available camera may be used to capture the frontal plane motion as a low-cost and more convenient tool to monitor bilateral kinetic asymmetries during double-leg squats in patients following ACLR.
