Management Protocol for Sport-Related Concussion in a 15-Year-Old Athlete
A 15-year-old athlete with a sport-related concussion must be immediately removed from play and should never return to sport the same day, even if symptoms resolve—this is non-negotiable. 1
Immediate Management (Day of Injury)
- Remove from play immediately when concussion is suspected
- No same-day return to play under any circumstances 1
- Remember: "When in doubt, sit them out!" 1
- Arrange evaluation by a healthcare professional experienced in concussion management 1
- Loss of consciousness >30 seconds warrants consideration of more serious intracranial injury 1
Initial Rest Period (First 24-48 Hours)
Complete physical and cognitive rest for the first 24-48 hours 2, 3:
- Limit screen time significantly
- Reduce cognitive demands (schoolwork, reading, video games)
- Avoid physical exertion
- Coordinate with school to modify academic workload 1
Critical caveat: Prolonged strict rest beyond 48 hours ("cocooning") until complete symptom resolution is NOT recommended and may actually delay recovery 2.
Active Recovery Phase (Starting Day 2-3)
Begin light physical activity as early as 48 hours post-injury if symptoms are stable 2, 3. This represents a major shift from older protocols:
- Early return to light activity (e.g., walking) safely facilitates recovery
- Meta-analysis shows physical activity and prescribed exercise improved recovery by mean of 4.64 days 2
- Brief, mild symptom exacerbation (≤2-point increase on 0-10 scale lasting <1 hour) during activity is not harmful and does not delay recovery 2
Graded Return-to-Play Protocol (Minimum 5 Days)
Once asymptomatic at rest, follow this stepwise progression with each stage lasting at least 24 hours 1:
Stage 1: Complete Rest
- Physical and cognitive rest until asymptomatic at rest
Stage 2: Light Aerobic Activity
- Walking, swimming, or stationary cycling at <70% maximum heart rate
- No resistance exercises
- Duration: 24 hours minimum
Stage 3: Sport-Specific Exercise
- Sport-related drills without head impact
- Still no contact
- Duration: 24 hours minimum
Stage 4: Non-Contact Training Drills
- More complex drills
- May begin light resistance training
- Duration: 24 hours minimum
Stage 5: Full-Contact Practice
- Requires medical clearance first
- Normal training activities with contact
- Duration: 24 hours minimum
Stage 6: Return to Play
- Normal game participation
If symptoms return at any stage: Stop immediately, rest for 24 hours after becoming asymptomatic again, then resume at the previous asymptomatic level 1.
Key Differences for Adolescents vs. Adults
Adolescents require more conservative management 1:
- Recovery typically takes 7-10 days or longer (vs. shorter in college/professional athletes)
- Cognitive recovery period is longer even after symptoms resolve
- More susceptible to concussions and may take longer to recover than adults 4
Specialized Interventions for Persistent Symptoms
If symptoms persist beyond 10 days 2:
- Consider cervicovestibular rehabilitation for dizziness, neck pain, or headaches
- Vestibular rehabilitation if dizziness persists >5 days
- Prescribed subsymptom threshold aerobic exercise treatment (based on systematic exercise testing) significantly reduces symptoms persisting beyond 30 days
If symptoms persist beyond 30 days 2:
- Active rehabilitation and collaborative care approach
- Consider referral to concussion specialist 1
Assessment Tools
Baseline and post-injury assessment should include 1:
- Symptom evaluation (standardized checklist)
- Cognitive assessment (e.g., Standardized Assessment of Concussion)
- Balance testing
- Neuropsychological testing (helpful but not solely diagnostic) 1
School Accommodations
Coordinate with teachers and administrators 1:
- Modify workloads to avoid symptom exacerbation
- Reduce cognitive demands during recovery
- Gradual return to full academic participation paralleling physical recovery
Red Flags Requiring Specialist Referral
- 3 concussions in one season 1
- Symptoms persisting >3 months 1
- Multiple previous concussions with prolonged recovery
- Uncertainty about return-to-play timing 1
What NOT to Do
- Never use medications routinely (safety and efficacy not established) 1
- Never enforce strict rest beyond 48 hours until complete symptom resolution 2
- Never allow return to play while symptomatic at rest or with exertion 1
- Never return to play same day even if asymptomatic 1
The evidence strongly supports early, gradual return to activity over prolonged rest, with a structured minimum 5-day progression before full return to competition. This approach reduces both symptom duration and risk of persistent post-concussive symptoms while maintaining safety 2.
