Inputs

Level of Consciousness (LOC) questions

Use another one-step command if the hands cannot be used.

Face and vision

Best gaze - horizontal eye movement.

Tested using finger counting or visual threat.

Ask the patient to show teeth or raise eyebrows and close eyes.

Limbs

The limb is placed in the appropriate position: extend the arms (palms down) 90 degrees (if sitting) or 45 degrees (if supine). Drift is scored if the arm falls before 10 seconds.

The limb is placed in the appropriate position: extend the arms (palms down) 90 degrees (if sitting) or 45 degrees (if supine). Drift is scored if the arm falls before 10 seconds.

Patient holds their left leg at 30 degrees (always tested supine). Drift is scored if the leg falls before 5 seconds.

Patient holds their right leg at 30 degrees (always tested supine). Drift is scored if the leg falls before 5 seconds.

Test with eyes open. In case of a visual defect, ensure testing is done in the intact visual field. The finger-nose-finger and heel-shin tests are performed on both sides, and ataxia is scored only if present out of proportion to weakness. Ataxia is absent in patients who cannot understand or are paralyzed.

Sensation and speech

Patient is asked to describe what is happening in a picture, to name the items on the attached sheet, and to read from the attached list of sentences. Intubated patient should be asked to write.

Formerly "Neglect". The presence of visual spatial neglect or anosognosia may also be taken as evidence of abnormality.

How to use the NIH Stroke Scale Calculator

  1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
  2. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
  3. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

score = responsiveness + month_and_age + command + best_gaze + visual + palsy + leftarm + rightarm + leftleg + rightleg + ataxia + sensation + language + dysarthria + extinction
