Abstract Summary
Injury to the anterior cruciate ligament (ACL) results in lingering quadriceps deficits leading to long-term dysfunction. A simple screening tool such as the Y Balance Test (YBT) may provide a surrogate measure of strength deficits. Quadriceps strength and dynamic balance using the YBT were assessed in ACL patients and controls. Significant moderate correlations were found between non-ACL anterior YBT reach and ACL strength scores (p < 0.05).
