The correct management of concussion data is critical in providing a high standard of care. CSX makes the collection of data, comparison to baselines and sharing of results easy. CSX utilizes multimodal tasks to collect cognitive data. Each task takes between 2-10 minutes. The CSX offering allows parents, coaches, trainers and health care practitioners to track brain health and share data on a secure platform. The platform contains the following Elite HIA protocols: • World Rugby Protocols • NRL Protocols • AFL Protocols • England and New Zealand Cricket Protocols • Soccer Protocol • New Zealand Rugby Rugby Smart CSX custom protocol. For the community level CSX General protocols includes: • Baseline tasks (pre-season), • Suspected Concussion logging and notifications • Post-injury and recovery assessments with comparison to the baseline • At home symptom tracking • Out of play activity calendar • Game-based brain tasks • UNLIMITED assessments and report sharing • Cloud always available storage • Doctor Code CSX is not intended to diagnose concussions or make return-to-play decisions. CSX is a tool to be used to collect data and help with the management of concussion as set out in concussion protocols. A complete concussion and return-to-play assessment should not be made based on the data in the app alone, and should only be made after a user has received a medical examination by a qualified healthcare professional. HealthKit data may be accessed when using the app in the Research Environment.
