The overall purpose of the Concussion Research Project (CRP) clinic is to optimize the assessment, management and follow-up for children who remain symptomatic three months following a sport-related head injury. Optimal care of patients with prolonged post-concussion symptoms includes a thorough medical evaluation and referrals to the appropriate specialties, including neurology, neurosurgery, the pain service and pediatrics. The focus is on providing a multidisciplinary approach to care that includes a collaborative management plan and appropriate follow-up. The knowledge gained from this research project will guide the development of preventive measures in children found to be at high risk of developing post- concussion syndrome.

Research Projects

  1. Symptom Burden, School Function, and Physical Activity One-Year Following Pediatric Concussion


    Most youth are symptom-free and fully recovered one year following concussion. Some children with repeat concussion have worse outcomes and have delays in returning to normal school routines and sport.

  2. Characteristics of Vomiting as a Predictor of Intracranial Injury in Pediatric Minor Head Injury


    Recurrent vomiting (≥ four episodes) was a significant risk factor for intracranial injury in children after minor head injury.

  3. Early versus delayed emergency department presentation following mild Traumatic Brain Injury and the presence of symptom at 1, 4 and 12 weeks in children


    We evaluated the association between timing of presentation and postconcussive symptoms (PCS) at 1, 4 and 12 weeks after injury.

  4. Natural Progression of Symptom Change and Recovery From Concussion in a Pediatric Population


    It may be that between-sex differences in adolescents should be taken into consideration for recovery management; the derived recovery curves may be useful for evidence-based anticipatory guidance.

  5. No association between metoclopramide treatment in ED and reduced risk of post-concussion headache


    Further research is necessary to determine which pharmacotherapies may be effective for acute and persistent post-concussive headache.

  6. Validation and refinement of a clinical decision rule for the use of computed tomography in children with minor head injury in the emergency department


    We sought to prospectively validate the accuracy and potential for refinement of a previously derived decision rule, Canadian Assessment of Tomography for Childhood Head injury (CATCH), to guide CT use in children with minor head injury.

  7. Multicentre, randomised clinical trial of paediatric concussion assessment of rest and exertion (PedCARE)


    This trial will determine if early resumption of non-contact physical activity following concussion reduces the burden of concussion and will provide healthcare professionals with the evidence by which to recommend the best timing of reintroducing physical activities.

  8. Clinical Risk Score for Persistent Postconcussion Symptoms Among Children With Acute Concussion in the ED


    A clinical risk score developed among children presenting to the emergency department with concussion and head injury within the previous 48 hours had modest discrimination to stratify PPCS risk at 28 days.
