What is the recommended treatment and stepwise return-to-activity protocol for a concussion?

Treatment for Concussion

No athlete should return to play on the day of injury, and complete physical and cognitive rest is no longer recommended beyond an initial 24-48 hours—instead, begin a supervised stepwise return-to-activity protocol once the patient is asymptomatic at rest. 1

Acute Management (First 24-48 Hours)

When any concussion symptoms are present:

• Remove from play immediately and do not allow return during the current game or practice 2
• Do not leave alone—regular monitoring for deterioration is essential 2
• Initial rest period: 24-48 hours of relative rest, not complete isolation 3
• After this brief rest, begin reintroducing normal daily activities as tolerated 4, 5

Critical principle: "When in doubt, sit them out!" 2, 1, 2

Red Flags Requiring Neuroimaging

Brain CT or MRI should be obtained if any of the following are present:

• Prolonged disturbance of consciousness
• Focal neurological deficits
• Seizure activity
• Persistent clinical or cognitive symptoms beyond expected timeframe 2

Stepwise Return-to-Activity Protocol

The patient must be completely asymptomatic at rest before beginning this protocol. 2, 1, 2 Each step takes a minimum of 24 hours, meaning the fastest possible return is 5-6 days. 3, 1, 3

The 6-Step Protocol:

1. Complete rest (24-48 hours only)

   • Physical and cognitive rest until asymptomatic at rest
   • Then proceed to step 2 2, 1, 2

2. Light aerobic exercise

   • Walking, swimming, or stationary cycling at <70% maximum heart rate
   • No resistance training
   • Duration: minimum 24 hours if asymptomatic 1

3. Sport-specific exercise

   • Running, skating, or sport-specific aerobic activities
   • No head impact risk
   • Duration: minimum 24 hours if asymptomatic 2, 1, 2

4. Non-contact training drills

   • More complex sport-specific drills
   • May begin light resistance training
   • Increased coordination and cognitive demands
   • Duration: minimum 24 hours if asymptomatic 1, 6

5. Full-contact practice

   • Return to normal training activities
   • Requires medical clearance before this step
   • Assess psychological readiness
   • Duration: minimum 24 hours if asymptomatic 2, 1, 2, 6

6. Return to game play

   • Full participation 2, 1, 2

If Symptoms Return During Protocol

Drop back to the previous asymptomatic level immediately. 2, 1, 2 Wait 24 hours after becoming asymptomatic again, then retry progression. 2, 1, 2

Special Considerations for Pediatric and Adolescent Athletes

Younger athletes require more conservative management because they demonstrate longer cognitive recovery periods (7-10 days or more) compared to college-aged or professional athletes. 1

• 14-16 year-olds take 3-4 days longer to progress through the protocol compared to 17-year-olds 7
• Females take longer than males to reach full clearance (21.6 vs 19.3 days on average) 7
• The return-to-school phase (steps 2-3) accounts for approximately half the total recovery time (10.2 days average) 7

Persistent Symptoms (>10 Days)

Symptoms persisting beyond 10 days require multidisciplinary management. 3 This affects approximately 15-20% of concussion patients. 8

Refer for specialized evaluation addressing:

• Headache management (often cervicogenic or migraine-type)
• Vestibular and oculomotor dysfunction requiring specific rehabilitation
• Sleep disturbances
• Cognitive rehabilitation if needed
• Behavioral health comorbidities (anxiety, depression) 9, 5

Critical Restrictions

Do not allow return to play while:

• Any symptoms persist at rest or with exertion 2, 1, 2
• Taking medications to mask concussion symptoms 3
• Medical clearance has not been obtained 2, 1, 2

Common Pitfalls to Avoid

• Prolonged complete rest beyond 48 hours is harmful—it can prolong recovery and is no longer recommended 4, 10, 5
• Same-day return to play is never acceptable, even if the athlete feels fine 2, 3, 1, 3, 2
• Rushing through the protocol—each step requires minimum 24 hours even if asymptomatic 3, 1, 3
• Ignoring return of symptoms—any symptom recurrence mandates dropping back a level 2, 1, 2

Return to Other Activities

For older adolescents and adults, discuss return to driving risks—cognitive deficits may persist even when patients report feeling asymptomatic, potentially compromising driving safety. 6

For students, implement graduated return to school with accommodations as needed (reduced workload, extra time for assignments, frequent breaks) before progressing through athletic return-to-play steps. 7
