• Baseline and post-injury symptom assessment in suspected sport-related concussion.
• Tracking recovery trajectory throughout the clinical management period.
• Standardized reporting in clinical and research settings.

• Physical: Headache, Nausea, Vomiting, Balance problems, Dizziness, Fatigue, Light/Noise sensitivity, Vision problems, Numbness/Tingling.
• Cognitive: Feeling slowed down, Feeling "in a fog", Difficulty concentrating, Difficulty remembering.
• Emotional: Irritability, Sadness, Nervousness, Feeling more emotional.
• Sleep: Drowsiness, Sleeping more/less than usual, Trouble falling asleep.

Research suggests symptoms often cluster into "Migrainous," "Vestibular," "Cognitive," and "Emotional" groups. High severity in specific clusters can help predict prolonged recovery and guide early targeted interventions (e.g., vestibular therapy).

• Baseline symptom scores are rarely 0 in healthy athletes (often 1–4 due to stress/lack of sleep).
• Symptom "provocation" during the SCAT6 maneuvers is a critical indicator even if the resting PCSS was low.
• Sudden spikes in PCSS during the Graduated Return-to-Play protocol indicate a need to step back to the previous stage.

• Score > 0: Generally indicates that the athlete is not fully recovered and should not resume contact sports.
• Declining Score: Demonstrates recovery progress and readiness to advance through stages of the GRTP.
• Persistent Symptoms: Symptoms lasting >4 weeks should trigger referral to a specialized concussion clinic.
