The Design and Evaluation of an Active Intervention for the Prevention of Non-contact ACL Injury

Not Applicable

Completed

• Conditions: Sprains and Strains; Wounds and Injuries; Athletic Injuries; Knee Injuries
• Interventions: Device: Activity Training with Feedback

• Registration Number: NCT01021111
• Lead Sponsor: Stanford University

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.

Detailed Description

This study will address the following specific aims: 1) To optimize a wearable, targeted, active training feedback device to reduce the risk of ACL injury among healthy subjects by inducing patterns of movement that alter the known kinematic and kinetic risk factors associated with ACL injuries. 2) To evaluate the efficacy of the active device and determine if the device reduces the risk of ACL injury among healthy subjects by effectively inducing patterns of movement that alter the known kinematic and kinetic risk factors associated with ACL injuries.

Arm && Interventions

Group	Intervention	Description
Activity Training with Feedback	Activity Training with Feedback	Subject is tested prior to training and retested with feedback training designed to modify the mechanics of landing during jumping and running activities

Primary Outcome Measures

Name	Time	Method
Knee Flexion Angle and Trunk Flexion Angle After Activity Training With Feedback	1 day	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 Outcome Measures

Name	Time	Method
Thigh Coronal Angular Velocity After Feedback Training	1 day	How fast the thigh is moving relative to the tibia during the activity, measured in degrees/second.
