A) LLRs normalized to background EMG activity (EMG of unperturbed trials) for the vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL), medial hamstrings (MH) and lateral hamstrings (LH) during the 50 – 150 ms time bin following the perturbation, for the Controls (dark bars) and ACLRs (open bars). Values are means ± SE. * represents significant difference between Controls and ACLR (p < 0.05). B) Time at which the long latency response peaked for each of the muscles tested during the unexpected perturbations of the single leg squat task for the Controls (filled circles) and ACLRs (open circles). Values are means ± SE. * represents significant difference between Controls and ACLR (p < 0.05).
