External Focus of Attention Feedback to Reduce Risk of Non-contact ACL Injury
Trial Parameters
Brief Summary
Knee injuries, especially those to the ACL, are common among physically active people. Preventing these injuries from happening is critical to limiting the long-term pain, disability, and arthritis associated with these injuries. Our study is going to examine new ways to provide feedback about the way people move to determine if these are better at modifying movement patterns to prevent injury than current standard treatments. If you participate, you will be asked to undergo a movement analysis in a research laboratory while you perform tasks such as landing from a box and running and cutting. After this initial assessment, you will be randomly allocated to one of 3 treatment groups. Each treatment group will perform 4 weeks (3x/week) of exercises to change the way people land from a jump. Participants will then report for follow-up movement analysis testing 1- and 4-weeks after completing the intervention.
