A comparative study of joint pain in adult and juvenile rheumatoid arthritis.

Material and Methods 24 children aged between 4 and 14 years and suffering from rheumatoid arthritis were included in this study. Eight of them were 7 years old or less. As controls we used thirty patients with rheumatoid arthritis between the ages of 18 and 51, of whom eight were over 40 and only one was under 20 years old. In each group 95 affected joints (190 altogether) were carefully analysed regarding pain. Only the wrists, elbows, knees, and ankles were taken into account (Table I).
