RACE Stroke Scale
Sum facial (0–2), arm (0–2), leg (0–2), head/gaze deviation (0–2), aphasia (0–2), extinction/agnosia (0–1). Total 0–9; higher scores suggest higher concern for LVO in many teaching pathways.

How it works
RACE aggregates six stroke examination domains to screen for possible large vessel occlusion alongside NIHSS and local triage tools.
Limits
Does not replace vessel imaging, NIHSS, or institutional triage thresholds; cutoffs vary by cohort and protocol.
Educational tool only—not for diagnosis or treatment decisions.
