Evaluation Of Digital Joint Circumference Measurements In Rheumatoid Arthritis

Abstract

Measurement of digital joint circumference by using a plastic spring gauge has been carefully evaluated in rheumatoid patients. There is very small Ultra-observer but large inter-observer variation. A diurnal change in joint size could not be confirmed. Provided that joints affected by soft tissue swelling are used, the measure is a useful Index of the effect of anti-inflammatory drugs.John Webb Centre for Rheumatic Diseases 35 Baird Street Glasgow, G. 40 EH Scotland
