The Graduated Return-to-Activity Protocol The current standard of care is the Graduated Return-to-Sport (GRTS) protocol, updated in the 2023 Amsterdam Consensus Statement on Concussion in Sport. This replaces all previous concussion management guidelines. The protocol has six stages, each lasting a minimum of 24 hours. Progression from one stage to the next requires completing the current stage without symptom exacerbation. If symptoms worsen at any stage, the patient returns to the previous stage and reattempts progression after 24 hours of symptom stability (Patricios et al., 2023). Stage 1: Symptom-limited activity (days 1-2). Daily activities that do not provoke symptoms. Light walking. Gentle range of motion exercises. Diaphragmatic breathing. The goal is relative rest, not complete rest. Activities that exacerbate symptoms are avoided. Activities that are tolerated are continued. Stage 2: Light aerobic exercise (day 2-3+). Walking, swimming, or stationary cycling at light to moderate intensity. Heart rate below 70% of maximum. No resistance training. Duration 15-20 minutes initially, progressing as tolerated. The purpose is increasing heart rate and cerebral blood flow without symptom exacerbation. Stage 3: Sport-specific exercise (day 5-7+). Running drills, skating drills, or sport-specific movement patterns. No head-impact activities. No contact. Progressive intensity up to 80% of normal training. The purpose is adding movement complexity and exercise intensity. Stage 4: Non-contact training drills (day 7-10+). Progressive resistance training resumes. Full training drills without body contact. Coordination and cognitive load increase. The purpose is restoring training capacity and confidence before contact. Stage 5: Full-contact practice (after medical clearance). Requires medical clearance to proceed. Full participation in practice including body contact. The purpose is restoring confidence and assessing functional readiness in a controlled environment. Stage 6: Return to competition. Full unrestricted participation. Normal game play. No restrictions. The Return-to-Learn Protocol For students, a parallel Return-to-Learn protocol applies: Stage 1: Daily activities at home. Brief screen use as tolerated. Light reading. Stage 2: Homework and reading in increased increments. Limited screen time with breaks. Stage 3: Partial school attendance with accommodations (reduced workload, extra time, quiet room for tests, movement breaks). Stage 4: Full school attendance with accommodations. Stage 5: Full school attendance without accommodations. Full cognitive workload. Academic accommodations include: extended deadlines, reduced homework volume, quiet testing environments, permission to take movement breaks, reduced screen time requirements, and permission to leave class if symptoms worsen. These accommodations are temporary bridges that support continued participation rather than the complete academic withdrawal previously recommended. Exercises for Each Protocol Phase JME 155 Diaphragmatic breathing: appropriate from Stage 1 through all stages. The foundation exercise for autonomic recovery. 10 breaths with 4-second inhale, 6-second exhale. 4 times daily. Autonomic regulation supports brain healing, exercise tolerance, sleep quality, and emotional regulation across all recovery phases. JME 14 Chin tucks: appropriate from Stage 1. Deep cervical flexor activation prevents cervicogenic complications. 5 repetitions initially (Stage 1), progressing to 10 repetitions with 5-second holds by Stage 2-3. Maintaining deep cervical flexor function throughout recovery prevents the cervicogenic headache pattern that complicates later stages. JME 1 Cervical rotation: appropriate from Stage 1-2. 5 repetitions at 50% range initially, progressing to 10 repetitions at full range by Stage 3. Cervical rotation maintains proprioceptive input, supports vestibular recalibration, and prevents cervical stiffness. This exercise addresses three recovery pathways simultaneously and is the highest-value cervical exercise during concussion recovery. JME 3 Lateral cervical flexion: appropriate from Stage 1-2. Addresses scalene and upper trapezius guarding. 5 repetitions per side initially, progressing to 8 repetitions with breathing holds by Stage 2-3. Early intervention prevents chronic cervicogenic patterns. Start your 14-day free trial for protocol-aligned concussion recovery programming. Progressive Exercises Stages 2-4 JME 153 Standing thoracic rotation: appropriate from Stage 2-3. Restores the thoracic mobility lost during the acute phase and reduces cervical compensation. 8-10 repetitions per direction. Essential for athletes preparing to return to rotational sports (throwing, swimming, golf, tennis) and desk workers returning to prolonged sitting. JME 42 Shoulder mobility: appropriate from Stage 2. Releases the protective shoulder posture that developed during Stage 1. 10 repetitions. Shoulder release reduces cervicogenic headache and improves cervical range of motion, supporting progression through the protocol. JME 150 Seated thoracic rotation: the primary work/study break exercise during return-to-learn and return-to-work progressions (Stage 2-5 of academic protocol). Every 60-90 minutes of cognitive activity, 8 repetitions per direction. Breaks the sustained posture that worsens cervical and autonomic symptoms during cognitive load. JME 151 Lateral side bends with breathing: appropriate from Stage 2-3. Combines cervical-thoracic mobility with autonomic support. 8 repetitions per side with full diaphragmatic breathing. The combined exercise supports physical recovery (mobility) and autonomic recovery (breathing) simultaneously, which accelerates progression through protocol stages. Follow the protocol with simplmobility's structured concussion recovery programs. Key Principles of the Current Protocol Symptom response guides progression, not time. The minimum time at each stage is 24 hours, but there is no maximum. A patient who is symptom-free at Stage 2 after 24 hours progresses to Stage 3. A patient who has symptom exacerbation at Stage 2 stays at Stage 2 until they tolerate the demands without worsening. The protocol is self-pacing. Faster recovery is not rewarded with faster progression. Symptom tolerance is the sole criterion. Mild symptom increase during activity is acceptable. The protocol does not require symptom-free activity. Symptom increase of 1-2 points on a 10-point scale during activity that resolves within 60 minutes is within the therapeutic zone. The patient progresses. Symptom increase of 3+ points or symptom increase that persists beyond 60 minutes indicates the current stage exceeds capacity. The patient returns to the previous stage. Multi-system assessment is recommended when recovery stalls. If a patient fails to progress through the protocol within expected timelines (2 weeks for adults, 4 weeks for adolescents), assessment of cervical spine function, autonomic function (Buffalo Treadmill Test), vestibular function, oculomotor function, and psychological status is recommended. Stalled recovery almost always indicates untreated secondary system dysfunction rather than delayed brain healing. Does the protocol differ for non-athletes? The brain healing timeline is identical for athletes and non-athletes. The return-to-activity progression applies universally. Non-athletes replace sport-specific stages with occupational-specific stages: return to driving, return to physical job demands, return to household activities. The principles (graduated progression, symptom-guided advancement, 24-hour minimum per stage) are the same. The specific activities within each stage are modified to match the patient's occupational and recreational demands (Patricios et al., 2023). What changed from the old protocol? The major changes from pre-2017 guidelines: rest period shortened from "until symptom-free" to "24-48 hours." Complete activity restriction replaced by symptom-limited activity from Stage 1. Aerobic exercise begins days 2-3 rather than after full symptom resolution. Multi-system assessment recommended when recovery stalls rather than continued observation. The shift is from passive management (wait for healing) to active management (treat specific systems, progress based on response). Does everyone need to follow the protocol exactly? The protocol provides the framework. Individual modification is expected. Patients with pre-existing migraine, anxiety, or ADHD may need modified progression rates. Patients with significant cervical or vestibular dysfunction need targeted treatment alongside the protocol. Children under 13 need longer minimum durations at each stage. The protocol is the foundation, not the ceiling. Individual clinical judgment modifies the protocol based on the specific patient's presentation and response. References Patricios, J. S., et al.
