Notes:
SD, standard deviation; ACLR, anterior cruciate ligament reconstruction group; H:M Ratio, hoffman reflex H-wave to M-wave ratio; MVIC, maximum voluntary isometric contraction (knee extension); CAR, central activation ratio; LSI, limb symmetry index (knee extension). Bold indicates a model with statistical significance.
