“The X2 system is the world’s first real-time, end-to-end head impact monitoring and concussion management system for athletes, and our goal is for widespread adoption by coaches, trainers, and physicians.  By immediately informing the sideline staff of head impact events on the field, and by providing SCAT2-based sideline concussion assessment tools, the X2 system supports improved outcomes of player brain health working in concert with the existing standard of care. The data we collect provides immediate utility to trainers, coaches, and physicians right now, and will be invaluable in supporting the future research that will revolutionize our understanding of this important injury.”

“Adopting the most cutting edge technology to maximize the level of concussion care we provide for our athletes is a decision whose time has come. As a user of the X2 system, I’m thrilled at how it streamlines our process and improves our visibility of what used to be an overwhelming amount of data.  The X2 system guides us in the latest standards for making bench vs play decisions and structures the recovery and return to play process. Team physicians and athletic trainers can do our jobs better and that makes the players feel more secure.”
