AGENDA: CONCUSSION MANAGEMENT UPDATE MEETINGSEAFAIR MINOR HOCKEY - NOVEMBER 8TH, 2013

  • Introduction: Medical Panel and Seafair Background on Baseline Testing and Concussion Management (Cody Kusch)

  • Background: Concussions and Recent Findings (Naznin Virji-Babul)

  • Medical Evaluation and Recovery Process (Dr. William Panenka)

  • 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)


Background
Background:

  • Concussion/mTBI currently considered a ‘silent epidemic’

  • Sports activities are a major cause of concussions

  • 300,000 sports related concussions occur each year in the United States


What happens to the brain during a concussion?


Shearing in the “wiring” of the brain


Issues for coaches clinicians parents
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
Advanced MRI can “see” subtle changes in the wiring of the brain

No concussion

Signs and symptoms of concussion
Signs and Symptoms of Concussion the brain

  • 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


Recovery from concussion how long does it take

Medical evaluation
Medical Evaluation the brain

  • 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
Persistently symptomatic patient the brain

  • 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

Table from Ontario NeurotraumamTBI Guidelines, and adapted from Current Treatment Options in Neurology. 2006;8:415-426


Child teenage athletes
Child/teenage athletes the brain

  • 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 successfully

  • 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
Issues in the field the brain

  • No “gold” standard for assessment

  • Return to play/learn protocols are based on “expert” opinion not hard evidence


Seafair study
Seafair the brain Study

  • Use 2 different assessments to evaluate which one is most sensitive

  • Never been done before


Baseline and end of season assessments
Baseline and End of season Assessments: the brain

  • SCAT3

    Baseline: 341 players tested to date

  • AXON

    Baseline: Only 73 completed to date



Return to play protocol
Return to play protocol the brain

  • 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
