Outline of Final Research Achievements

Anterior Cruciate Ligament (ACL) injuries often occur during reactive movements, such as unanticipated (UN) side-step. This study aimed to investigate whether the UN condition is more risky than the anticipated (AN) condition during step task and whether the reactive step exercises are useful for ACL injury prevention.
This study indicated that UN side-steps increase knee abduction and rotational moment. This suggested that UN tasks may help identify the risk of knee ligament injury.
Injury prevention program including reactive step exercises was performed. After this program, trunk lateral inclination and rotation to step side were decreased. This result suggested that reactive step exercises are important to decrease the risk of ACL injuries.
