Electromyographic assessment of agonist and antagonist muscles related to the anterior cruciate ligament following surgical Reconstruction: A Cross-Sectional study.

Background: Following anterior cruciate ligament reconstruction (ACLR), neuromuscular control alterations may persist, increasing the risk of reinjury.

Objectives: This study aimed to investigate electromyographic (EMG) muscle activation and the co-contraction index (CCI) of ACL-related agonist and antagonist muscles during side-hop tasks in ACLR individuals, offering novel insights into neuromuscular strategies during dynamic tasks.

Methods: A cross-sectional study was conducted with 15 ACLR individuals and 15 participants without ACL injury (N-ACLR).
