Trends in movement quality in US Military Academy cadets 2005-17: A JUMP-ACL study

This study sought to determine if there were significant trends in lower extremity movement quality, as assessed by the Landing Error Scoring System (LESS) scores and plane-specific LESS subscales, across in 12 recent cohorts of incoming USMA cadets.prospective cohort study.United States Military Academy.7,591.Landing Error Scoring System (LESS) scores, adjusted for sex and ACL injury history.Statistically significant inverse trends were found between total LESS score and year (p 0.01) and sagittal plane subscale and year (p 0.01). A statistically significant direct trend was found for the frontal/transverse plane subscale and year (p 0.01). However, each of these trends had a small associated effect size, and none were considered clinically meaningful.There were no meaningful changes in lower extremity movement quality in incoming US Military Academy cadets between 2005 and 2017.
