Abstract: Methods and systems for detecting overstride in runners include measuring, using an inertial measurement unit affixed to a shank of a person, an acceleration and an angle of the shank during a stride, monitoring, using a microprocessor, the shank acceleration measurements to detect an acceleration profile indicative of the corresponding foot making initial contact with the ground during the stride, determining, using the microprocessor, the corresponding shank angle at initial contact from the shank angle measurements, comparing, using the microprocessor, the shank angle at initial contact to a threshold shank angle, and identifying, using the microprocessor, an overstride of the corresponding leg if the shank angle at initial contact exceeds the threshold shank angle.
