Arms outstretched 90° (if patient is sitting) or 45° (if supine) for 10 seconds. Encourage best effort, note paretic side. Raise leg to 30° (always test patient supine) for 5 seconds. Check finger-nose-finger; heel-shin; score only if out of proportion to weakness.
What is the NIH stroke scale NIHSS and how is it performed?
The NIHSS neurologic examination includes 15 individual elements that measure motor and sensory function, language and speech production, vision, level of consciousness and attention, and neglect. The elements are summed to provide an overall assessment of stroke severity, with the score ranging from 0 to 42.
What is the NIH stroke scale range?
The scoring range is 0 to 42 points, with higher numbers indicating greater severity. A score of <5 represents no stroke symptoms or a minor stroke, a score of 5 to 15 represents a moderate stroke, a score of 16 to 20 represents a moderate to severe stroke, and a score of 21 to 42 represents a severe stroke.
What is the stroke assessment scale?
Methods— The new stroke scale assessed 3 parameters: (1) level of consciousness, (2) gaze, and (3) motor function. Each item was graded 0 to 2, where 0 indicated normal findings and 2 severe abnormalities (ie, profound drowsiness or worse, forced gaze deviation, and severe hemiparesis, respectively).
How does NIH scoring work?
The NIH utilizes a 9-point rating scale (1 = exceptional; 9 = poor) for all applications; the same scale is used for overall impact scores and for criterion scores (Scoring Guidance).
Who can administer the NIH stroke scale?

Is there a stroke scale?
The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS), is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4.
What is a good NIH score?
Impact scores run from 10 to 90, where 10 is best. Generally speaking, impact/priority scores of 10 to 30 are most likely to be funded; scores between 31 and 45 might be funded; scores greater than 46 are rarely funded.
What is the severity of a patient's stroke if they have a NIHSS of 4?
The NIHSS score is defined as the sum of 15 individually evaluated elements, and ranges from 0 to 42. Stroke severity may be categorized as follows: no stroke symptoms, 0; minor stroke, 1–4; moderate stroke, 5–15; moderate to severe stroke, 16–20; and severe stroke, 21–42 [6, 7].
What is the stroke Impact Scale?
The Stroke Impact Scale (SIS) assesses other dimensions of health related quality of life: emotion, communication, memory and thinking, and social role function. *The first four of these domains may be combined into one physical domain, but the others must be scored separately.
How many stroke scales are there?

Why is the NIH stroke scale important?
It is used on admission to determine patient eligibility for thrombolytic therapy, throughout the acute hospital stay, and at 3 months to assess neurologic recovery. The NIH stroke scale scores correlates with initial infarct volume, cerebral perfusion, and functional outcome.
How long does it take to do NIH stroke scale certification?

A stroke is a serious health condition that occurs when blood flow to the brain is either restricted or interrupted. It is the fifth most common cause of death and a leading cause of disability in the United States. 1
Why is the NIHSS important?
Another important use of the NIHSS is in research, where it allows for the objective comparison of efficacy across different stroke treatments and rehabilitation interventions. 3 This can help researchers determine, with uniform criteria, whether a medical treatment is effective in the treatment of stroke.
Why do stroke care teams use NIHSS?
The NIHSS is one of the tools that your stroke care team uses to communicate in a consistent manner, particularly because there are many different people on your stroke care team who are involved in caring for you as you recover from your stroke.

What is the stroke scale?
The National Institutes of Health (NIH) Stroke Scale is a widely used method for evaluating the severity of stroke symptoms. The scale provides a comprehensive but efficient neurological assessment that scores the severity of the patient's symptoms, and allows physicians to compare the deficits over time. An initial baseline scale should be assessed as soon as possible after the onset of symptoms, and then assessments should be undertaken at regular intervals throughout care.
What to do after rapid assessment?
After a rapid assessment, you recognize these are symptoms of a stroke and triage the patient immediately. The patient is sent off for a CT scan, and physicians begin a treatment plan with anticoagulants. But how do you know if the treatment is working, and whether the patient is better or worse?
What does it mean to enroll in a course?

Is the NIH stroke scale accurate?
However, the accuracy of the NIH Stroke Scale may depend on the type and location of stroke. For example, the severity score may be higher when stroke is in the left brain due to the impact on verbal processing and its value within the exam.
Can a stroke scale be used to evaluate treatment?
Providers may use NIH Stroke Scale scores to guide and evaluate treatment, but the American Heart Association (AHA) discourages using scores as a sole reason for delaying treatment. For example, physicians shouldn't exclude a patient from treatment only because they currently exhibit a low stroke scale score.
When administering the exam, should the nurse or provider work quickly and write down the score after each part of the exam?
Score the patient based on his or her first attempt at the task, and only score exactly what the patient does, not what you think they are capable of doing. Be careful not to coach or physically assist the patient.
