When the sensor detects a potentially dangerous impact or series of impacts, it vibrates on the athletes head to alert them. It also pushes an alert to the app to notify parents and coaches that the player should be removed from play for a sideline evaluation. On the sideline the player can complete a brief in-app evaluation accompanied by a checklist of symptoms to look for. If even one symptom is present, the athlete should not return to activity until they've been evaluated by a trained medical professional.

Disclaimer: The Jolt Sensor is not a concussion diagnostic tool. Concussions can only be diagnosed by a trained medical professional. The Jolt Sensor provides an objective measure of the quantity and magnitude of head impact forces and is intended to direct athletes towards more timely medical assessment.
