The RACE scale is a prehospital simple and rapid neurological scale to detect acute stroke patients with a high probability of having a large vessel occlusion, candidates to be treated with endovascular techniques in a comprehensive stroke center.
The RACE scale is a simplification of the NIHSS scale using those items with a higher ability to predict the presence of a large vessel occlusion. The RACE scale evaluates 5 items: facial palsy, brachial paresis, crural paresis, oculocephalic deviation and aphasia/agnosia, with a total score of 0-9.
A score ≥ 5 indicates the possibility of a large vessel occlusion with a sensitivity of 85% and specificity of 69%.
