Lauren Church Sport, Health & Physical Education Vancouver Island University Concussions in Ice Hockey
Why Is This An Issue? • 57 individuals have dealt with a concussion • 3 individuals with multiple concussions or head injuries • 1102 man games missed in the NHL
Why Is This An Issue? • 2009: Concussion knowledge questionnaire completed in the Greater Toronto Area2 • 267 players (atom, bantam, AA & HL competitive levels) • 142 adults (coaches, parents & trainers) • 25 percent of adults & 25 to 50 percent of players could not recall any concussion symptoms or only one symptom
Why Is This An Issue? • 2009: Concussion knowledge questionnaire completed in the Greater Toronto Area2 • 267 players (atom, bantam, AA & HL competitive levels) • 142 adults (coaches, parents & trainers) • 50 percent of players & 20 percent of adults incorrectly stated that concussions are treated with medication or physical therapy
Why Is This An Issue? • 2009: Concussion knowledge questionnaire completed in the Greater Toronto Area2 • 267 players (atom, bantam, AA & HL competitive levels) • 142 adults (coaches, parents & trainers) • 25 percent of players did not know if an athlete experiencing concussion symptoms should continue playing
Why Is This An Issue? • 2009: Concussion knowledge questionnaire completed in the Greater Toronto Area2 • 267 players (atom, bantam, AA & HL competitive levels) • 142 adults (coaches, parents & trainers) • 66 percent of players did not know it was possible to sustain a concussion without losing consciousness
What Is a Concussion? • “A complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces.”5 • Clinical, pathological and biomechanical injury constructs may be used to define the nature
Signs and Symptoms Table 1. Common Signs and Symptoms of a Concussion4
Grading Scales • There are at least 27 systems proposed1 • Typically the 3 systems used are: • Cantu • American Academy of Neurology • Colorado Medical Society • 75% of concussions do not result in a loss of consciousness; therefore, new scales have been developed which address this3
On Ice Assessment • Number of different tools available • Hockey Canada – Sport Concussion Assessment Tool 2 (SCAT 2) • 8 components • Symptom evaluation • Physical signs score • Glasgow coma scale (GCS) • Sideline assessment – Maddocks score • Cognitive assessment • Balance examination • Coordination examination • Cognitive assessment • These combine for a total score
Risk Factors • Facial protection • In-game fatigue • Ice size • Collision type & frequency • Chin strap & mouthguard use • Age • Gender
