The Standardized 6-Stage Protocol The return to play (RTP) protocol is the international standard for safe sport re-entry after concussion. Developed through the Consensus Statement on Concussion in Sport, it provides a structured progression from complete rest to unrestricted competition (McCrory et al., 2017). The protocol serves two purposes: it tests your brain's tolerance to progressively increasing physiological stress, and it rebuilds the physical conditioning lost during rest. Each stage adds metabolic, cognitive, and physical demand. Completing all stages without symptom recurrence confirms readiness for competition. No stage should be skipped. No stage should be shortened below 24 hours. The protocol works because each step builds on the previous one, systematically confirming your brain handles the demands of the next level. Stage-by-Stage Breakdown Stage 1: Symptom-limited activity. Activities of daily living that don't worsen symptoms. Walking, light household tasks, work or school with accommodations. No structured exercise. Duration: continue until symptom-free at rest for 24+ hours. Most athletes spend 3-7 days here. Stage 2: Light aerobic exercise. Heart rate 50-70% of maximum. Walking briskly, stationary cycling, or swimming at easy pace. 15-20 minutes. No resistance training, no sport-specific drills. The goal is cardiovascular activation without head impact risk or excessive metabolic demand. Stage 3: Sport-specific exercise. Running drills, skating drills, or sport-specific movement patterns. No contact, no collision activities. Heart rate 70-80% of maximum. 30-45 minutes. This stage tests your brain under sport-related metabolic and cognitive demand. Stage 4: Non-contact training drills. Full training complexity without body contact. Progressive resistance training. Coordination drills, tactical exercises, team practices (non-contact portions). This stage tests cognitive processing under physical fatigue. Stage 5: Full-contact practice. Requires medical clearance before beginning. Normal practice including contact. This stage restores confidence, tests reactive balance and decision-making under contact conditions, and allows coaches to assess game readiness. Stage 6: Return to competition. Full unrestricted participation. Normal game play, full intensity, no restrictions. How the Protocol Works in Practice Minimum timeline: 6 days from symptom resolution (one day per stage). If symptoms resolved on day 7 post-injury, the earliest possible competition return is day 13. In practice, most athletes take 10-21 days from injury. If symptoms return at any stage: Drop back to the last symptom-free stage. Rest for 24 hours. Then resume the protocol from that stage. Each setback extends your timeline by a minimum of 48 hours. Symptom monitoring: Track symptoms before, during, and after each session using a standardized checklist (SCAT5 or similar). Any increase of 2+ points on a 0-6 severity scale for any symptom indicates the stage was too demanding. Exercise intensity: Monitor heart rate during Stages 2-4. Rate of perceived exertion (RPE) provides a secondary measure. If exercise feels harder than expected relative to the intensity level, your brain is working harder than normal to sustain effort. Cervical Preparation Throughout the Protocol Neck conditioning begins during Stage 1 and progresses through each subsequent stage. Strong, mobile cervical muscles reduce future concussion risk and support the physical demands of sport: JME 1 Cervical rotation restores range of motion needed for sport-specific awareness (Stage 1+). JME 5 Controlled rotation builds cervical-visual coordination for tracking during play (Stage 2+). JME 22 Wide rotation develops the full cervical range needed for athletic scanning (Stage 3+). JME 6 Cervical flexion prepares for head positions encountered during sport contact (Stage 3+). Upper Body Conditioning by Stage JME 42 Shoulder mobility maintains upper body function during early protocol stages. JME 68 Progressive shoulder work builds the upper body conditioning needed for later stages. JME 153 Thoracic extension supports upright athletic posture and spinal function. JME 164 Thoracic rotation develops the rotational mobility needed for most sport activities.

Who Manages the Protocol Professional and collegiate athletes have athletic trainers and team physicians managing daily progression. Each stage is supervised, documented, and evaluated before advancing. High school athletes should have their protocol managed by certified athletic trainers where available. Many states require school-based concussion protocols. Parents should confirm their child's school has a written concussion management plan. Recreational athletes often self-manage the protocol. Use a symptom checklist, track heart rate during exercise stages, and get medical clearance before Stage 5. When in doubt, advance more slowly. An extra day at any stage costs nothing compared to the risk of premature return. Common Protocol Mistakes Combining stages. "I'll do light exercise and sport-specific drills in the same day." Each stage tests a specific demand level. Combining them creates uncertainty about which demand triggered any symptoms. Ignoring cognitive symptoms. Athletes often focus on physical symptoms while ignoring increased difficulty concentrating, memory problems, or slower processing during training. Cognitive symptoms during the protocol indicate incomplete recovery. Pressure to return. Coaches, teammates, and scholarship concerns create pressure to compress timelines. No competitive benefit justifies the risk of catastrophic second impact. Communicate the protocol timeline clearly to all stakeholders. Skipping medical clearance. Stage 5 requires physician clearance for good reason. Self-assessed "feeling fine" doesn't detect subtle cognitive deficits or balance problems that clinical evaluation reveals. After Completing the Protocol Monitor symptoms during the first 2-4 weeks of full competition. Game-day intensity, travel fatigue, irregular sleep, and accumulated training load expose any residual vulnerability. If symptoms return during competition, withdraw immediately and restart the protocol. Maintain cervical conditioning as an ongoing practice. Strong neck muscles reduce head acceleration during impact, providing measurable protection against future concussion. Neck strength is one of the few modifiable risk factors for concussion prevention. Maintain concussion-protective neck strength with simplmobility's ongoing cervical health programs for athletes. FAQ How long does the return to play protocol take? Minimum 6 days from symptom resolution (one day per stage). Average total time from injury to competition return is 10-21 days. Athletes with prolonged initial symptoms, previous concussions, or younger age typically take longer. The protocol cannot be safely compressed below 6 days. What happens if symptoms return during the protocol? Return to the last stage completed without symptoms. Rest for 24 hours. Resume from that stage. Each symptom recurrence extends the timeline by at least 48 hours. If symptoms return at the same stage three times, consult a concussion specialist for evaluation. Does every sport use the same protocol? The 6-stage framework is universal, but sport-specific applications vary. Stage 3 exercises differ between hockey, soccer, and basketball. Stage 5 contact intensity varies by sport. The underlying principle of graduated return with symptom monitoring applies to all sports. Do I need the protocol for non-contact sports? Yes. The protocol tests your brain's tolerance to increasing physiological stress, not contact readiness. Even runners, swimmers, and cyclists benefit from graduated return because exercise intensity affects the recovering brain regardless of impact risk. References McCrory, P., et al. (2017).
