“Concussion may be caused either by a direct blow to the head, face, neck or else where on the body with an ‘impulsive’ force transmitted to the head.” (Play it Cool, 2010)
What is a concussion?
From the “Play it Cool” website
“Concussion typically results in the rapid onset of short-lived impairment of neurologic function that resolves spontaneously.” Examples include: Nausea, double or fuzzy vision, sensitivity
to light or noise, headache, feeling sluggish, feeling foggy or groggy, concentration or memory problems, confusion
Concussion Symptoms
Tuesday, February, 26, 2010 Running an on-ice practice with the
varsity girls hockey team, I collided with a student & hit my head on the ice (I was wearing a helmet) Symptoms:
Dizzy Felt sick to my stomach Was spacey (a.k.a. – I was out of it) Headaches for about 2 weeks
My Concussion History
Tuesday, March 2, 2010 Hit in the back of the head with a
hard rubber ball while playing European handball with the grade 12 co-ed class Symptoms:
Instant headache (has not gone away) I was totally out of it Vision in left eye was blurry, out of focus, & I
was seeing lines across my eye
My Concussion History
The Globe & Mail (Tuesday, March 9, 2010) Concussion effects linger for decades, study finds
The Globe & Mail (Monday, March 8, 2010) Concussions can’t be eliminated completely
National Post (Thursday, February 25, 2010) NFL combine puts more emphasis on concussions

You can suffer a concussion while engaging in sports such as hockey, football, soccer, boxing and other sports, or leisure activities, for example tobogganing
In the past 2.5 years, 200 concussions have been reported
among NHL players (Globe Sports, 2010, Section R7)
“Close to 10% of minor hockey players suffer concussions
each year” (The Globe & Mail: Concussion effects linger for decades, 2010)
“According to the Centers for Disease Control and Prevention, between 1.4 and 3.6 million sports and recreation-related concussions occur each year, with the majority happening at the high school level.” (Science Daily, 2007)
Relevance to students
“Traditional brain scanning techniques such as MRI and CT are helpful in viewing changes to the brain anatomy in more severe cases, but cannot identify subtle brain-related changes that are believed to occur on a metabolic rather than an anatomic level.” (Science Daily, 2007)
ImPACT Test Immediate Post-Concussion Assessment & Cognitive
Testing Used a baseline and for post-concussion comparison) Measures multiple aspects of cognitive functioning
including neurological tests that look at word discrimination, X’s & O’s, colour match, symbol matching, visual attention span (http://www.impacttest.com/)
Scanning Technology
The Messier Project “... is an all-encompassing grassroots and
educational initiative which aims to change priorities in the sport by encouraging athletes to play smart and choose the best protective equipment.” (http://www.cascadeicehockey.com/the-project.html)
The Technology “Seven Technology is tuned to absorb impact using
lateral displacement, providing the protection of two helmets in the space of one – one for catastrophic hits and one for concussions.” (http://www.cascadeicehockey.com/the-technology.html)
