What it calculates

The β€œNIH Stroke Scale (NIHSS)” calculator computes NIHSS total score from 15 parameters: 1a. level of consciousness (0–3), 1b. loc questions (0–2), 1c. loc commands (0–2), 2. best gaze (0–2), 3. visual fields (0–3), 4. facial palsy (0–3), 5a. left arm motor (0–4), 5b. right arm motor (0–4), 6a. left leg motor (0–4), 6b. right leg motor (0–4), 7. limb ataxia (0–2), 8. sensory (0–2), 9. best language, aphasia (0–3), 10. dysarthria (0–2), 11. extinction and inattention (0–2).

A professional calculation for specialists.

Example calculation

With parameters 1a. Level of consciousness (0–3) = 0, 1b. LOC questions (0–2) = 1, 1c. LOC commands (0–2) = 0, 2. Best gaze (0–2) = 1, 3. Visual fields (0–3) = 0, 4. Facial palsy (0–3) = 2, 5a. Left arm motor (0–4) = 3, 5b. Right arm motor (0–4) = 0, 6a. Left leg motor (0–4) = 2, 6b. Right leg motor (0–4) = 0, 7. Limb ataxia (0–2) = 0, 8. Sensory (0–2) = 1, 9. Best language, aphasia (0–3) = 1, 10. Dysarthria (0–2) = 1, 11. Extinction and inattention (0–2) = 1 the result is 13 (Untestable items (amputation, intubation) are not added to the total).

How to use

  1. Enter 1a. level of consciousness (0–3), 1b. loc questions (0–2), 1c. loc commands (0–2), 2. best gaze (0–2), 3. visual fields (0–3), 4. facial palsy (0–3), 5a. left arm motor (0–4), 5b. right arm motor (0–4), 6a. left leg motor (0–4), 6b. right leg motor (0–4), 7. limb ataxia (0–2), 8. sensory (0–2), 9. best language, aphasia (0–3), 10. dysarthria (0–2) and 11. extinction and inattention (0–2) β€” each field above is adjustable with a slider.
