Concussion Management: Assessment, Treatment, and Return-to-Activity Protocol
Immediately remove any patient with suspected concussion from activity and do not allow same-day return to play under any circumstances—"When in doubt, sit them out!" 1, 2
Initial Assessment and Recognition
When evaluating for concussion, assess across multiple clinical domains:
- Cognitive symptoms: Confusion, difficulty concentrating, memory problems
- Physical symptoms: Headache, nausea, balance impairment, visual changes
- Emotional symptoms: Irritability, emotional lability, anxiety
- Sleep disturbances: Insomnia or excessive drowsiness 2, 3
Activate EMS immediately if any of these red flags are present:
- Loss of consciousness
- Severe or worsening headache
- Repeated vomiting
- Altered mental status or seizures
- Visual changes
- Skull deformities or swelling 2
These warning signs indicate potential life-threatening complications (epidural hematoma, subdural hematoma, skull fracture, or brain edema) requiring emergency evaluation.
Acute Management (First 24-48 Hours)
Initial rest should be limited to 24-48 hours only—prolonged strict rest is no longer recommended and may be detrimental. 4, 5 After this brief period, begin gradual reintroduction of daily activities as tolerated. The outdated approach of absolute cognitive and physical rest until asymptomatic is now contraindicated based on current evidence.
Start light daily activities including walking within 24 hours of injury, keeping activity below the symptom threshold (activities should not significantly worsen symptoms) 5, 3.
Stepwise Return-to-Activity Protocol
The graduated return-to-play protocol requires a minimum of 5 days, with each stage lasting at least 24 hours. 1 This is non-negotiable—no shortcuts are permitted.
Six-Stage Progression:
Stage 1: Complete Physical and Cognitive Rest
- Duration: 24-48 hours maximum
- No activity beyond basic daily living
- Once asymptomatic at rest, advance to Stage 2
Stage 2: Light Aerobic Activity
- Walking, swimming, or stationary cycling at 70% maximum heart rate
- No resistance exercises permitted
- Duration: Minimum 24 hours if asymptomatic
Stage 3: Sport-Specific Exercise
- Sport-related drills without head impact risk
- Running for soccer, skating for hockey, etc.
- Duration: Minimum 24 hours if asymptomatic
Stage 4: Non-Contact Training Drills
- More complex drills with increased coordination demands
- May begin light resistance training
- Duration: Minimum 24 hours if asymptomatic
Stage 5: Full-Contact Practice
- Requires medical clearance before proceeding
- Return to normal training activities
- Assess psychological readiness
- Duration: Minimum 24 hours if asymptomatic
Stage 6: Return to Play
Critical Management Rules:
If symptoms return at any stage:
- Stop activity immediately
- Rest for 24 hours until asymptomatic
- Resume at the previous asymptomatic level (drop back one stage)
- Contact healthcare provider if symptoms recur 1
The patient must remain completely asymptomatic at rest AND with exertion before advancing through stages. 1
Special Considerations for Pediatric and Adolescent Athletes
Younger athletes require more conservative management—cognitive recovery takes 7-10 days or longer in pediatric/adolescent populations compared to college-aged athletes. 1 This is a critical distinction often overlooked. Even when asymptomatic, younger patients need additional time before full return to contact sports due to prolonged cognitive recovery periods.
Prolonged Symptoms (>10 Days)
Patients with symptoms persisting beyond 10 days require multidisciplinary management by a physician experienced in concussion care. 1, 7 This should include:
- Specialty-specific referrals based on symptom profile
- Vestibular rehabilitation for balance/dizziness
- Cognitive rehabilitation for persistent cognitive symptoms
- Exercise therapy programs 4, 8
For adolescents specifically, there is sufficient evidence to recommend exercise as appropriate therapy for acute concussion. 4
Common Pitfalls to Avoid
Never allow return to play while taking medications for concussion symptoms 7—this masks symptoms and prevents accurate assessment
Never permit same-day return to play, even if the athlete appears asymptomatic 1, 9, 7—this is the most dangerous error in concussion management
Avoid prolonged strict rest beyond 48 hours 4, 5—evidence shows this delays recovery rather than helping it
Do not rush the 24-hour minimum per stage 1—the 5-day minimum protocol exists for physiological reasons, not convenience
For athletes with multiple prior concussions or prolonged symptoms, standard protocols are insufficient—these patients require individualized, extended rehabilitation programs 1
The evidence strongly supports this structured, conservative approach prioritizing brain recovery over rapid return to competition, ultimately protecting long-term neurological function and quality of life.
