Research, not medical advice

trace* is a research project. The interactive demo and the brain-strain predictions it shows are intended for research demonstration only. They are not a medical device, do not constitute clinical advice, and must not be used to make decisions about return to play, diagnosis, or treatment. If you have a medical concern about head injury, please consult a qualified clinician.

Sample data

The kinematic recordings shown in the demo are a fixture dataset shared with the iOS prototype. They illustrate the pipeline; they do not represent any specific athlete or incident.
