Feedback Cues Improve the Alignment and Technique of Children Performing ACL Injury Prevention Exercises

This study that Dr. Marx conducted examined the appropriateness of neuromuscular training exercises in precenting ACL injuries across different age groups, particularly in younger children. The purpose of this study was to determine which neuromuscular training exercises can be performed with proper neutral alignment in various age groups. A total of 360 participants were evaluated (8-11 years: 165, 54% female; 12-15 years: 136, 40% female, 16-17 years: 59, 53% female). There were no significant differences in performance across ages and sex for nearly all exercises. The majority of children were not able to complete the exercises with proper alignment. The use of feedback cues significantly increased the proportion of participants who correctly completed the exercise (p<0.001).
