Medical practitioners use the National Institutes of Health Stroke Scale, or NIHSS, in evaluatingstroke severity. The NIHSS International, which is part of the International Electronic Education Network, is a collaborative program by the United States federal agencies, international governments and educational institutions that are involved in the advocacy of stroke patients.
The NIHSS was primarily developed as a tool for gauging initial data during clinical examinations of peoplediagnosed with an acute stroke. The scale is the most commonly usedfor stroke patients, according to a 2010 study published in the U.S. National Library of Medicine. An improved version of NIHSS called modified NIHSS, or mNIHSS, has been proposed by the authors to replace NIHSS in medical practice.
