dc.description.abstractObjective: To investigate compensatory and anticipatory quadriceps muscle activations before and after anterior cruciate ligament reconstruction (ACLR) using hamstrings tendon graft. Design:Twelve participants who underwent ACLR and 12 healthy controls were exposed to 10 either unpredictable or predictable perturbations of the knee joint before ACLR (T1), 2 months (T2) and 6 months (T3) after surgery. Latencies of compensatory and anticipatory postural activations in the vastus lateralis (VL), rectus femoris (RF) and vastus medialis (VM) muscles were recorded by surface electromyography with respect to the arrival of the perturbations. Results:Latency of compensatory activations was significantly delayed in ACLR compared to that in healthy participants at T1 for VL (105 ± 25 vs. 57 ± 9 ms; P<0.001), RF (102 ± 23 vs. 56 ± 9 ms; P<0.001) and VM (107 ± 24 vs. 66 ± 16 ms;P<0.001), at T2 for VL (68 ± 14 vs. 55 ± 10 ms;29 P<0.01) and at T3 for VL (105 ± 22 vs. 58 ± 7 ms;P<0.001), RF (102 ± 22 vs. 58 ± 12 ms; P<0.001) and VM (106 ± 20 vs. 63 ± 8 ms;P<0.001). Anticipatory activations occurred earlier in ACLR than in healthy participants at T1 for VL (-82 ± 64 vs. -14 ± 11 ms; P<0.05) and VM (-105 ± 32 68 vs. -9 ± 12 ms;P<0.05). Conclusion:While anticipatory quadriceps activations show no alterations, compensatory muscle activations are delayed following ACLR with hamstring graft. Post-surgical rehabilitation should address alterations in compensatory lower limb postural control.en_US
