International scale for assessment of disability in multiple sclerosis.

The Minimal Record of Disability (MRD) is an assessment tool developed under the auspices of the International Federation of Multiple Sclerosis Societies. It represents a synthesis of several scales designed to assess disability and handicap in patients with multiple sclerosis. This article will define the Minimal Record of Disability and other scales, explain the pertinent components and numerical values of each, and describe the field testing conducted for the MRD. Implications for nursing will also be considered.
