Concussion testing is commonly done using paper forms or not at all. This is a huge issue given the permanent or fatal risks of concussed athletes returning to sport. HeadCheck provides a novel sideline concussion testing app allowing for quick and accurate decision making directly from the sideline. Many organizations do not have the resources to set up their own protocol,preventing necessary tasks such as baseline testing and training of individuals tasked with sideline concussion management. HeadCheck provides onboarding services to organizations,including sending certified medical professionals to their location to set up a concussion protocol. Organizations currently lack the ability to know whether their concussion protocol is being followed properly,leaving them open to liability. HeadCheck provides compliance analysis and reporting back to organizations,giving them complete transparency into risks such as teams not following the protocol appropriately.
