Historical perspectives on evolving operational definitions of concussive brain injury: From railway spine to sport-related concussion.

Conclusions: Two differing operational definitions of concussion are in the current use, involving the presence vs. absence of PTA. These two groupings are not clinically similar, although they are currently being widely treated as such. Operational definitions of concussion should address both minimum and maximums for duration of PTA, initial Glasgow Coma Scale score, complications, and symptom presence.
