Currently, jumplanding feedback interventions have demonstrated the ability to alter movements that increase the risk of ACL injury during landing. Unfortunately, it remains unknown if jump-landing interventions, which demonstrate the ability to alter movements during a jump-landing task, can alter similar movements in a different task, such as a cutting maneuver. The specific aims of this randomized control trial was to determine the effects of a jump landing feedback intervention on 1) the kinetics and 2) the kinematics performed during an anticipated cutting maneuver and a jump-landing task compared to a control group. Our central hypothesis was that biomechanical alterations known to occur during a jump-landing task, following a jump landing feedback intervention, will also be altered during a cutting maneuver. We used separate repeated measures ANOVAs to evaluate differences in kinetics and kinematics between feedback and controlgroups overtime. The results of this study revealed a significant decrease in peak vertical ground reaction force (VGRF) in the feedback group during the jump landing task but not the cutting task. Neither group improved knee flexion angles during the jump landing task, while the feedback group became more extended at the knee joint compared to the control during the cutting task. Both groups demonstrated an improvement in hip flexion over time in the jump landing task, but not the cutting task. Lastly, neither group demonstrated a change in knee abduction angles during either of the tasks. The findings of the study do not entirely support our hypotheses, but we would expect to find more differences with more participants added to the sample size. While the results were not what we expected, they have provided us with insight into the limitations of a feedback intervention and in order to improve future prevention programs, it is imperative to understand the limitations of the feedback intervention.","abstract_html":"There is a critical need to develop cost and time-effective prophylacticinterventions to decrease the risk of anterior cruciate ligament (ACL) injury.
