Identifying Concussions:
Step-by-Step Key Signs and When to Act
How to Use the Concussion Assessment Checklist
Follow these steps in order. If any step indicates a positive finding (e.g., red flags, observable signs, abnormal test results), suspect a concussion and take appropriate action.
Step 1: Look for Red Flags
If any of these are present seek emergency medical care:
Loss of consciousness
Seizures or convulsions
Vomiting
Severe or worsening headache
Weakness or numbness in limbs
Step 2: Check for Observable Signs
Watch for these indicators:
Lying motionless after impact
Falling unprotected to the surface
Balance or gait difficulties, motor incoordination, or stumbling, slow/laboured movements
Disorientation or confusion, staring, limited responsiveness, or inability to answer questions appropriately
Blank or vacant expression
Facial injury following head trauma
Impact seizure
High risk mechanism of injury (i.e A fall from a height greater than 3 feet/5 stairs, load to the head such as diving injuries, use of motorised recreational vehicles, bicycle collisions)
If any of these occur, seek medical advice and concussion support
Step 3: Glasgow Coma Scale (GCS)
Step-by-Step Instructions to Use the Glasgow Coma Scale
1. Prepare for Assessment:
Record the time and date of the assessment.
Ensure the patient is in a safe environment for evaluation.
2. Evaluate the Patient's Responses:
A. Eye Opening Response (E) - ask “Can you open your eyes”
No eye opening = 1 point
Opens eyes to pain = 2 points
Opens eyes to speech = 3 points
Opens eyes spontaneously = 4 points
B. Verbal Response (V) - ask “What is your name”
No verbal response = 1 point
Incomprehensible sounds = 2 points
Inappropriate words = 3 points
Confused but able to respond = 4 points
Oriented and coherent = 5 points
C. Motor Response (M) - ask “can you grasp and release my fingers with your hand, then stick out your tongue”, if non responsive gently squeeze their trapezius muscle for 3s and look for their response.
No motor response = 1 point
Extension to pain (decerebrate) = 2 points
Abnormal flexion to pain (decorticate) = 3 points
Flexion/withdrawal to pain = 4 points
Localizes pain = 5 points
Obeys commands = 6 points
3. Calculate the Total GCS Score:
Add the scores for Eye Response (E), Verbal Response (V), and Motor Response (M).
Total score range: 3 to 15.
4. Interpret the Score:
Score <15: Seek immediate medical attention (this is a red flag).
Score ≥15: Proceed to the next step in the concussion evaluation protocol.
Step 5: Coordination and Vision Screening
Finger-to-Nose Test: Ask the athlete to extend their arm and touch their nose 5 times with both eyes open and closed. Test both left and right sides.
Ocular Motor Test: Have them move their eyes up, down, and side to side while keeping their head still. Watch for:
Double vision
Jerky or abnormal eye movements
If test is positive, seek medical advice and concussion support
Otherwise proceed to the next step in the concussion evaluation protocol.
Step 4: Assess for Neck Injuries
Ask if the athlete feels neck pain or tenderness:
If neck pain or tenderness is present, or loss of neck motion: Immobilise the neck and call an ambulance.
If no neck issues: Proceed to the next step.
Step 6: Maddock’s Questions
Ask the following questions to assess orientation and memory, tailor this to your situation.
Where are we today?
What period/half is it now?
Who scored last in this match?
What team did we play last week/game?
Did your team win the last game?
If any questions are incorrect, seek medical advice and concussion support
If all answers are correct, proceed to the next step.
Step 7: Symptom severity score of the SCAT6
to rule in a concussion, look for any increase of two or more symptoms compared to usual.
Symptoms can include:
Physical Symptoms:
Headaches
Pressure in head
Neck pain
Nausea or vomiting
Dizziness
Blurred vision
Balance problems
Sensitivity to light
Sensitivity to noise
Cognitive Symptoms:
Feeling slowed down
Feeling like "in a fog"
"Don’t feel right"
Difficulty concentrating
Difficulty remembering
Emotional Symptoms:
More emotional
Irritability
Sadness
Nervous or anxious
Energy Levels and Sleep:
Fatigue or low energy
Confusion
Drowsiness
Trouble falling asleep (if applicable)
Why Early Evaluation Matters
The prognosis for concussion is directly related to the time taken to see a healthcare practitioner, with earlier evaluation and treatment associated with better outcomes. Delayed clinical evaluation has been linked to more persistent and severe concussion symptoms in up to 40% of cases when left untreated.
Don’t wait to take action—your quick response could make a significant difference in recovery and long-term health.
