Abstract

One aim of this study was to describe inflammatory activity, joint destruction, work status, and demographic factors in a group of 69 American Rheumatism Association functional class-II rheumatoid arthritis patients: 56 women and 13 men, mean age 54 years (SD 11), mean symptom duration 14 years (SD 11). Another aim was to determine correlations between activity-induced pain and other variables. Patients were assessed with Ritchie's articular index, Larsen's radiologic index, and laboratory tests. Deformity in hands and knee joints, and grip strength, were determined. Results from earlier investigations of functional impairment and psychosocial capacity were also used. Of the patients, 4% had high inflammatory activity. Joint erosions were found in between 4% (knee joints) and 55% (wrists) of the joints examined. Of the patients aged less than 65, 43% were working. Activity-induced pain was related with work status (p = 0.0002). It also correlated significantly (p less than or equal to 0.01) with inflammatory activity (r(s) = 0.34), but not with joint destruction (r(s) = 0.21).
