NIH Stroke Scale (NIHSS) Score Calculator

Calculates the NIH Stroke Scale (NIHSS) neurological deficit score (0–42) across 11 items: level of consciousness (0–3), gaze (0–2), visual fields (0–3), facial palsy (0–3), arm motor (0–4 each), leg motor (0–4 each), limb ataxia (0–2), sensory (0–2), language/aphasia (0–3), dysarthria (0–2), extinction/inattention (0–2). Guides thrombolysis eligibility and outcomes prediction.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates the NIH Stroke Scale (NIHSS) neurological deficit score (0–42) across 11 items: level of consciousness (0–3), gaze (0–2), visual fields (0–3), facial palsy (0–3), arm motor (0–4 each), leg motor (0–4 each), limb ataxia (0–2), sensory (0–2), language/aphasia (0–3), dysarthria (0–2), extinction/inattention (0–2). Guides thrombolysis eligibility and outcomes prediction

Each component has a specific meaning:

  • 11 items: level of consciousness — The 11 items: level of consciousness recorded for the scenario being assessed.
  • Gaze — The gaze recorded for the scenario being assessed.
  • Visual fields — The visual fields recorded for the scenario being assessed.
  • Facial palsy — The facial palsy recorded for the scenario being assessed.
  • Arm motor — The arm motor recorded for the scenario being assessed.
  • Leg motor — The leg motor recorded for the scenario being assessed.

Note: Interpret the nihss stroke scale result against the thresholds and context described above.

How to Use

Enter the 11 items: level of consciousness, gaze, visual fields, facial palsy, arm motor, leg motor for the scenario you are assessing. Calculates the NIH Stroke Scale (NIHSS) neurological deficit score (0–42) across 11 items: level of consciousness (0–3), gaze (0–2), visual fields (0–3), facial palsy (0–3), arm motor (0–4 each), leg motor (0–4 each), limb ataxia (0–2), sensory (0–2), language/aphasia (0–3), dysarthria (0–2), extinction/inattention (0–2). Guides thrombolysis eligibility and outcomes prediction. Use the nihss stroke scale result to inform your calculation.
