Brief Summary
The overall goal of this project is to reduce the risk for anterior cruciate ligament injuries by designing a targeted intervention that will alter the known kinematic and kinetic risk factors associated with ACL injuries.

Outcome Measures
Primary Outcomes (1)
Knee Flexion Angle and Trunk Flexion Angle After Activity Training With Feedback
Knee flexion angle describes the angle between the tibia and femur during the activity. Trunk flexion is the angle between the shoulders and the hips during the activity.

Secondary Outcomes (1)
Thigh Coronal Angular Velocity After Feedback Training

Study Arms (1)
Activity Training with Feedback
EXPERIMENTALSubject is tested prior to training and retested with feedback training designed to modify the mechanics of landing during jumping and running activities
Interventions
The feedback system consisted of three small inertial measurement units affixed on the chest, thigh, and shank segment respectively. These units were connected to a computer that recorded the signal from the inertial sensors at 240 Hz during the jump task. Using custom software, the knee flexion angle, trunk lean, and coronal thigh angular velocity were calculated immediately after the subject completed the jump trial. A projector was used to display the results of the jump analysis. It took less than 10 minutes to place this system on a subject and less than five seconds to analyze a jump.
