NCIt definition : A standardized clinical classification originally developed by John Rankin in 1957,
and later modified by Van Swieten et al in 1988, which is used to assess the degree
of disability or dependence in the daily activities of individuals who have suffered
a stroke. It also allows comparison between subjects with different kinds of neurologic
deficits. The questionnaire contains a '0 to 6' scale, ranging from 'no symptoms at
all' (scored 0) to 'dead' (scored 6).;
Alternative definition : CDISC: Modified Rankin Scale (MRS) (Van Swieten J., Koudstaal P., Visser M., Schouten
H., and Van Gijn J. Interobserver agreement for the assessment of handicap in stroke
patients, 1988. Stroke 19: 604-607). CDISC believes this instrument to be in the public
domain, but you should perform your own assessment.;
