EDSS; Kurtzke expanded disability status scale


The Expanded Disability Status Scale (EDSS) is based upon the original Kurtzke Disability Status Scale (DSS) and Functional Systems (FS) (Kurtzke 1961). There are eight FSs: pyramidal, cerebellar, brainstem, sensory, visual, bowel and bladder, cerebral or mental, and other. Following neurological examination, each FS is rated on a scale of 0-5 (cerebellar and brainstem), 0-1 (other), and 0-6 (all others). These ratings assist in assigning an EDSS score which ranges from 0 to 10 in 0.5 increments, where 0 indicates a normal neurological examination (but cerebral grade 1 allowed) and 10 corresponds to death due to multiple sclerosis (MS) (see Kurtzke 1983for a full description of the rating scale). In general, EDSS scores ranging from 1.0 to 4.5 quantify the disability/impairment experienced by individuals with MS who are ambulatory, while EDSS scores from 5.0 to 9.5 correspond to disability/impairment of individuals...
