The american college of rheumatology 1991 revised criteria for the classification of global functional status in rheumatoid arthritis

Abstract

Although there are limitations inherent in the use of global ordinal scales, the American College of Rheumatology revised criteria will be useful in describing the functional consequences of RA. A more detailed quantitative measure of physical disability should be used, however, for optimal monitoring of patients' clinical status in office practice and clinical research.
