The Prevent mobile app pairs with the Prevent Biometrics impact monitor mouthguard. The Prevent system provides near real-time, accurate head impact data to help teams make the right call about player safety. The Prevent app is designed for sideline monitoring of head impacts for the whole team, and is typically used by athletic trainers, coaches and athlete parents. For every head impact, see five key impact characteristics: * Linear acceleration of the head * Rotational acceleration of the head * Direction of the impact * Location on the head of the impact * Impact Load (a composite measure factoring impact count and magnitude) View head impact data on a player or team basis, and over the timeframe of a day, week or sports season. Introduce actionable, objective data into the process of identifying athletes needing sideline evaluation. The Prevent app provides live alerts of high magnitude head impacts. See athletes with high head impact exposure and instruct them on safer playing technique. Stand for smart play. The Prevent system helps you understand head impacts across the team and organization and be a leader in improving sports safety, performance and growing the game. This app requires at least one Prevent Impact Monitor Mouthguard to operate. Learn more at preventbiometrics.com or contact sales@preventbiometrics.com.

L’application EZTM (Evaluation Zoom Team Management) est une véritable plateforme digitale médico-sportive entre les staffs médicaux, les staffs techniques et les sportifs. L'interface sur mesure est adaptée à la taille de l’institution, à son niveau et à sa spécialité. Elle permet : - de relever des informations « terrain » au quotidien , de les classer et de les analyser sous forme de datas, - de manager toutes les actions de travail, de les quantifier et de les organiser, - de modéliser toutes les séances d’exercices et de les mettre en place en les contrôlant et en les périodisant. - de communiquer et de coordonner instantanément avec tous les intervenants de manière précise et ciblée. Afin d’utiliser l’outil en temps réel, intuitivement et efficacement nous avons développé notre système sur des tablettes tactiles connectées. La motivation première fut d’optimiser, de dématérialiser et de digitaliser toute l’expertise professionnelle.
