The M.D.R. index is a new instrument which has been designed to give a measurement of physical function in inflammatory joint disease. It is very easy to apply and is not time-consuming. In preliminary assessment, the index has proven to be highly reliable. It has also been sufficiently sensitive to detect short-term changes in functional capacity which were unrelated to changes in the severity of joint inflammation. The application of the index is inexpensive and does not require extensive training of personnel for its accurate use. It is expected that the M.D.R. index will prove to be suitable for widespread use as a clinical assessment of physical function.
