Wearable gait analysis system for measuring overstriding in runners

Summary

Roughly 50% of the 20 million active runners in the United States are injured each year, with overstriding being a major cause.  Proper gait is essential to minimizing the risk of injury, but perfecting it requires constant monitoring of one's running form over a significant period of time.

This invention is a wearable system to measure a runner’s overstride.  Unlike the present approach, which is limited to treadmills in lab training centers, it provides a mechanism for continuous monitoring and feedback.  The invention consists of a 9-degree of freedom inertial measurement unit (IMU), attached to the anterior tibia via a compression sleeve.  A zero or negative angle is considered good form.

By providing feedback on overstriding, the device not only reduces injury, but also significantly improves running efficiency.
