Stanford University·interventional·Posted Nov 26, 2009·Updated Apr 21, 2017

In Brief

A clinical study evaluating Activity Training with Feedback for Athletic Injuries and 3 related conditions. Completed, enrolled 17 participants across 1 site.

Detailed 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.

Interventions

Activity Training with Feedbackdevice

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.
