In the July-September 2001 issue of
the Journal Of Athletic Training devoted exclusively to the subject of
concussions in athletes, I proposed some modifications to a set of
concussion grading guidelines I first issued in 1986 based on my
experience in the fifteen years since.
The following chart compares the two:
