After a suspected concussion the question is not whether an athlete performs well on a test, it is whether they perform like themselves. Reaction time, balance and recall vary enormously between individuals. A baseline recorded when healthy turns a vague judgement into a comparison. Without one, a genuinely impaired athlete with naturally strong scores can look fine.
A symptom inventory the athlete scores themselves. Cognitive measures covering orientation, immediate and delayed recall, and concentration. A balance assessment across several stances. Where the sport and budget support it, computerised neurocognitive testing of reaction time and visual memory. The set is chosen so it can be repeated on a sideline, not just in a clinic.
A baseline taken on a noisy sideline after a hard session is not a baseline, it is a distorted reading that will make a future concussion look milder than it is. We test in a quiet space, before or well after exertion, and we will say when conditions were not good enough rather than record the session anyway.
Baseline testing does not diagnose concussion, does not decide return to play on its own, and is not a substitute for removing an athlete who shows signs of injury. Any athlete with suspected concussion comes out and is assessed by a qualified clinician. The baseline informs that assessment; it does not replace it, and any provider suggesting otherwise is overselling.
