2.0 Draft
  • This measure was re-evaluated to fit the definition of a clinical classification measure. The domain was changed from the QS to RS domain.
  • The EDSS v2.0 supplement was updated to the wiki Clinical Classifications supplement template.

The Kurtzke Expanded Disability Status Scale (EDSS) and Kurtzke Functional Systems Scores (KFSS) instruments are intended to be used in conjunction with one another. The KFSS should first be administered by the evaluator and ; results from this assessment are then applied to determine an EDSS scale score (Kurtzke, 1983). A change in the EDSS should only occur if there has been a change of one 1 or more in the Functional System (FS)
