“…The kinematic analysis used in our previous study 17 identified values that were almost identical to those from the present method. The differences in the results from the two methods (previous method minus present method) were: peak flexion 0.5° (IC95%=0.4°-0.6°), peak extension 0° (-0.5°-0.4°), range of flexion/extension 0.5° (0.1°-1°), peak valgus -0.5° (-0.7°--0.4°), peak varus -0.5° (-0.8°--0.3°) and valgus/varus range 0° (-0.3°-0.3°).…”

“…For this, the 1st and 99 th percentiles, and the 99 th minus the 1 st percentile of the angle distributions, were calculated for 60s of the central part of the gait (the same method as used in our previous study 17 ), for 81% of the recordings (29 out of 36). The reference position was derived in the same way, and for the same time period, for both methods.…”

“…All significance tests were performed at a predetermined alpha level of 0.05. Although no power calculation was made, the sample size was based on studies published in the literature (see Coury et al 17 , Manal et al 22 , Kurz et al 23 , Lavcanska, Taylor e Schache 24 ).…”

“…In a recent study 17 in which we applied eccentric isokinetic training of the quadriceps muscles to subjects who had undergone ACL reconstruction, the knee extensor torque and flexion/ extension range of motion (ROM) during gait increased significantly after training. However, unexpectedly increased valgus, which was most pronounced during the swing phase, along with increased valgus/varus ROM.…”

Background We have previously reported that an eccentrically-based rehabilitation protocol post-ACLr induced greater quadriceps activation and strength than a neuromuscular electrical stimulation (NMES) intervention and was just as effective as a combined NMES and eccentric intervention. However, the effect an eccentrically-based intervention has on restoring normal knee mechanics during a single-legged landing task remains unknown. Methods Thirty-six individuals post-injury were placed into four treatment groups: NMES and eccentrics, eccentrics-only, NMES-only, standard of care, and Healthy controls participated. NMES and eccentrics received a combined NMES and eccentric protocol post-reconstruction (each treatment 2x per week for 6 wks), whereas groups NMES-only and eccentric-only received only the NMES or eccentric therapy, respectively. To evaluate knee mechanics limb symmetry, the area under the curve for knee flexion angle and extension moment was derived and then normalized to the contralateral limb. Quadriceps strength was evaluated using the quadriceps index. Findings Compared to Healthy, reduced sagittal plane knee limb symmetry was found for groups NMES-only, ECC-only and standard of care for knee extension moment (P<0.05). No difference was detected between Healthy and NMES and eccentrics (P>0.06). No difference between groups was detected for knee flexion angle limb symmetry (P>0.05). Greater knee flexion angles and moments over stance were related to quadriceps strength. Interpretation The NMES and eccentrics group was found to restore biomechanical limb symmetry that was most closely related to Healthy individuals following ACL reconstruction. Greater knee flexion angles and moments over stance were related to quadriceps strength.
