Abstract

The purpose of this study was to identify and evaluate the effectiveness of new gait metrics to dynamically assess healthy limb performance in post anterior cruciate ligament reconstruction (ACLR) individuals. Metrics comparing the active-to-impact peaks (AIP) ratio and late-to-mid knee flexion angle (LMKF) ratio were extracted from the vertical ground reaction force and knee flexion angle waveforms, respectively, to identify healthy limb loading dynamics during running. One variable binary logistic model was used to model healthy limb loading based on the AIP and LMKF metrics. The metrics successfully aided in the delineation between healthy and pathological movement dynamics. These findings are important because it identifies new metrics that are not dependent on the performance of the individuals non-reconstructed limb to quantify their reconstructed limb function.
