Concussion PPT presentation - Seafair Minor Hockey Association

Sports-related concussion in children
and adolescents
• Introduction: Medical Panel and Seafair Background on
Baseline Testing and Concussion Management (Cody Kusch)
• Background: Concussions and Recent Findings (Naznin VirjiBabul)
• Medical Evaluation and Recovery Process (Dr. William
• Baseline Testing: SCAT 3 and Axon, update on testing to date,
protocol for study, Return to play Protocol (Jonathan Sun)
• Panel: Question and Answer Period (Cody, Bill, Naznin, Dr.
Will Panenka, Jonathan Sun, Dr. Paul Korn)
• Concussion/mTBI currently considered
a ‘silent epidemic’
• Sports activities are a major cause of
• 300,000 sports related concussions
occur each year in the United States
What happens to the brain during a
Shearing in the “wiring” of the brain
Issues for coaches/clinicians/parents:
• Standard neuroimaging tools not
sensitive to detect subtle changes in
brain structure and function
• Diagnosis and evaluating functional
recovery very difficult
Advanced MRI can “see” subtle
changes in the wiring of the brain
No concussion
Concussed athlete
fMRI measures “thinking”
Brain activity is more “scattered”
Signs and Symptoms of Concussion
• By an observer – not only LOC!
Dazed or stunned, confused about assignment
Forgets instruction, game score, opponent
Off balance, answers slowly, loses consciousness
Mood, behavior or personality changes.
Amnesia for events around injury
• By the athlete –
Headache, nausea or vomiting
Balance problems or dizziness
Double or blurry vision
Sensitivity to light or noise
Concentration or memory problems, confusion

Medical Evaluation
• Individual clinical decision
• A medical assessment including a comprehensive history
and detailed neurological examination including a
thorough assessment of mental status, cognitive
functioning and gait and balance.
• A determination of the clinical status of the patient
including whether there has been improvement or
deterioration since the time of injury. This may involve
seeking additional information from parents, coaches,
teammates and eyewitness to the injury.
• A determination of the need for emergent
neuroimaging in order to exclude a more severe brain
injury involving a structural abnormality
Persistently symptomatic patient
• Persistent symptoms (>10 days) in about 10-15%
• Important to consider other issues
• Should be managed in multidisciplinary manner by
healthcare providers experienced in sport concussion

Child/teenage athletes
• Consider age specific physical and cognitive rest issues
– school attendance and activities need to be modified
• No return to sport or activity until returned to school
• Symptom resolution may take longer, modifiers apply
even more
• More conservative RTP approach recommended:
– Consider extending symptom-free period before starting return
to play protocol
– Consider extending length of the graded exertion protocol
• Never return to play same day
Issues in the field
• No “gold” standard for assessment
• Return to play/learn protocols are based on
“expert” opinion not hard evidence
Seafair Study
• Use 2 different assessments to evaluate which
one is most sensitive
• Never been done before
Baseline and End of season
Baseline: 341 players tested to date
Baseline: Only 73 completed to date
Concussion Protocol
Suspected Concussion
Coach/Manager pulls player off the ice
SCAT3/AXON repeated
Referral to BCCH/Dr. Korn/Dr. Panenka as needed
Dr. ‘Naz’ to screen players for MRI study
Must be within 1 week of concussion
Repeat scan if symptomatic at 6 weeks
Return to play protocol
• 1. No Activity. Complete physical and cognitive rest
• 2. Light aerobic exercise (Walking, swimming or stationary
cycling keeping intensity <70% maximum predicted heart rate.
No resistance training
• 3. Sport-specific exercise (Skating drills in ice hockey, running
drills in soccer. No head impact activities)
• 4. Non-contact training drills. Progression to more complex
training drills, e.g. passing drills in football and ice hockey.
May start progressive resistance training
• 5. Full contact practice following medical clearance,
participate in normal training activities
• 6. Normal game play
