The general objective is to develop and test a prototype ACL Gold computer software utilizing the Microsoft Kinect motion sensor that includes a screening tool and intervention to help prevent ACL tears in female youth athletes. The program measures the knee abduction angle during specific jumping and cutting tasks. High knee abduction angles have previously been shown to be risk factors for ACL rupture. ACL Gold will enable health care providers, coaches and parents to identify athletes at increased risk of suffering an ACL tear and begin injury prevention programs on those athletes. These programs typically incorporate exercises that improve core strength, decrease single leg dominance, increase hamstring strength.
- Develop and validate the accuracy of the ACL Gold algorithms against Vicon marker-based motion capture for measurement of knee angles during a Drop Vertical Jump
- Develop the ACL Gold screening software which includes a user interface and instant reporting of knee angles during the Drop Vertical Jump.
- Measure knee angles during the drop box vertical jump in over 100 high school athletes who compete in soccer, basketball or volleyball and follow during the academic year for ACL injuries
- Perform a feasibility survey of high school athletes to evaluate the potential use of a video game intervention that incorporates ACL injury prevention exercises and immediate biofeedback on landing/cutting technique.
