Hamstring co-contraction in the early stage of rehabilitation following anterior cruciate ligament reconstruction: A longitudinal study

Objective Hamstring co-contraction may affect recovery from anterior cruciate ligament reconstruction (ACLR). We aimed to evaluate the changes in hamstring co-contraction during the early postoperative stages. Design Twenty-five patients with ACLR were followed up for 1-3 months postoperatively, during which the Lysholm and International Knee Documentation Committee (IKDC) questionnaires were completed and surface electromyograms (sEMG) were assessed during terminal knee extension maximum voluntary contraction (TKE-MVC) and step-up tests. The integrated electromyogram of the tested muscles and co-contraction ratio (CR) were analyzed. Results CR during TKE-MVC at 3 months postoperatively was significantly less than that at 1 month postoperatively (p
