Comparison of the National Institutes of Health Stroke Scale With Disability Outcome Measures in Acute Stroke Trials

Comparison of the National Institutes of Health Stroke Scale with disability outcome measures in acute stroke trials.

BACKGROUND AND PURPOSE Acute stroke trials typically use disability scales as their primary end point. Neurologic impairment scales such as the National Institutes of Health Stroke Scale (NIHSS) are possibly more sensitive to change in patient status. We aimed to compare a range of potential NIHSS end points with modified Rankin Scale (mRS) and Barthel Index (BI) end points. METHODS We simula...

National Institutes of Health Stroke Scale (NIHSS).

Using change in the National Institutes of Health Stroke Scale to measure treatment effect in acute stroke trials.

BACKGROUND AND PURPOSE Outcome measures in acute stroke trials are being refined. Changes in neurological deficits might be useful outcome measures because they can measure the entire spectrum of deficits. METHODS We analyzed data from the acute stroke treatment trial Trial of Org 10172 in Acute Stroke Treatment (TOAST). Using logistic regression analysis, we modeled the probability of the TO...

Remote evaluation of acute ischemic stroke: reliability of National Institutes of Health Stroke Scale via telestroke.

BACKGROUND AND PURPOSE Despite Food and Drug Administration approval of tissue-type plasminogen activator for stroke, obstacles in the US healthcare system prevent its widespread use. The Remote Evaluation for Acute Ischemic Stroke (REACH) program was developed to address these issues in rural settings. A key component of stroke assessment in the REACH system is the National Institutes of Healt...

The National Institutes of Health Stroke Scale: Its Role in Patients with Posterior Circulation Stroke.

The National Institutes of Health Stroke Scale (NIHSS) is indispensable for both prognosis and treatment in patients with acute ischemic stroke. However, there is subtype of acute ischemic stroke (i.e., posterior circulation stroke) that is difficult to diagnose using the NIHSS. The authors report the limits of NIHSS in this stroke subtype, suggesting thereby the need to modify and render it mo...
