RACE score = facial palsy + arm motor impairment + leg motor impairment + head and gaze deviation + one side-dependent cortical item.

Domain	0 points	1 point	2 points
Facial palsy	Absent	Mild	Moderate to severe
Arm motor impairment	Normal to mild	Either arm falls within 10 seconds	Unable to raise either arm
Leg motor impairment	Normal to mild	Either leg falls within 5 seconds	Unable to raise either leg
Head and gaze deviation	Absent	Present	—
Aphasia for right hemiparesis	Performs both commands correctly	Performs one command correctly	Performs neither command correctly
Agnosia for left hemiparesis	Recognises the affected arm and the weakness	Recognises either the affected arm or the weakness	Recognises neither the affected arm nor the weakness

Use aphasia or agnosia according to the side of hemiparesis, not both. Total score range: 0–9. A score ≥5 indicates a higher probability of large-vessel occlusion.
