We prospectively determined the risk of initial stinger experience in
a group of college football players while considering the presence of
cervical canal stenosis and each player's position, playing time, and
body type. Prospective analysis revealed a 7.7% incidence of initial s
tinger experience. The average Torg ratio for all players was 0.924 +/
- 0.122, with the seventh cervical level being the narrowest. Initial
stinger experience depended on position played and body type. The Torg
ratio did not influence initial stinger occurrence. Players who exper
ienced multiple stingers, however, had significantly smaller Torg rati
os than players experiencing only one stinger (0.75 versus 0.87). A To
rg ratio of 0.70 may be a more statistically and clinically appropriat
e threshold for determining significant cervical stenosis and advising
collegiate athletes of their risk of experiencing recurrent stingers.
