Given the rising rates of concussion in youth ages 10-19 and the significant proportion of young people who remain symptomatic for months following concussion, research evaluating the efficacy of multifaceted treatment options following concussion is imperative. Studies examining the efficacy of treatment strategies following concussion in children and adults are surprisingly limited, and most focus on one treatment approach, have small sample sizes, are not randomized controlled trials, and focus on individuals with prolonged recovery (months). There is a need for a multifaceted treatment trial to examine the early implementation of treatment approaches that may reduce prolonged recovery while considering the heterogeneous presentation of symptoms and patient preferences in the sub-acute stage following concussion. Randomized controlled trials that consider a multifaceted transdisciplinary approach to treatment in the early period following concussion are needed to raise the bar regarding evidence-informed management following concussion

The primary objective of this RCT is to examine if up to 6-weeks of symptom-specific (1. headache, 2. dizziness and/or neck pain) treatment initiated in the acute/sub-acute stages following concussion in 13-19 year-old participants recruited acutely (within 2 weeks) following concussion are superior to up to 6 weeks of a multimodal, non-symptom specific treatment program. Treatment will cease once participants are cleared to return to unrestricted physical activity by a sports medicine physician, and will therefore last up to 6 weeks. We have two primary outcomes:

1. Post-Concussion Total Symptom Score (PCSS /132) on the SCAT5 following treatment of up to six sessions
2. Days from injury to physician clearance to return to unrestricted physical activity (e.g., physical education, sport, recreational activities)

Inclusion Criteria:

• 13 - 19 years of age at the start of treatment
• Diagnosed by the study physician with a concussion as per the 5th International Consensus Statement on Concussion in Sport1

• Loss of consciousness < 30 minutes if present
• Post-traumatic amnesia < 24 hours if present
• Diagnosis within 2 weeks of injury
• Moderate-severe symptoms of dizziness, neck pain, headaches, or sleep disturbance at > one week and < three weeks post injury reported on the PCSS (3-6 on 0-6 Likert scale for at least one of three symptoms)
• Patients can have a history of migraine or a family history of migraine

Exclusion Criteria:

• Inability to communicate orally and/or in writing in English language

• Unresolved Benign Paroxysmal Positional Vertigo (BPPV) (Dix-Hallpike and Roll Test)
• Inability to participate in physical activity for a reason other than concussion
• Orthopedic or other injury precluding ability to participate
