title: [Multidisciplinary treatment rheumatoid arthritis. Statistical and clinical change in pain experience].
abstract: BACKGROUND
  To date only few studies have been reported on the effect of multidisciplinary inpatient treatment on pain experience in patients with rheumatoid arthritis (RA). Aims of the present research were: to asses the development of different pain qualities at the beginning, at the end of treatment and at a follow-up three months later in a RA-patient sample as a whole, to determine statistically and clinically significant changes on individual base, and to study pain coping behaviors as predictive and pain-change associated variables.
  
  
  METHODS
  Subjects were 66 patients with a diagnosis of RA. They were treated with non-steroidal antiphlogistic and disease modifying drugs as well as with physical therapy. Measurement instruments were the pain experience scale with 5 subtests, the four-dimensional questionnaire of pain behavior, the functional disability scale, and a joint-index.
  
  
  RESULTS
  At follow-up the reduction was strongest in the quality of persistent pain experience (effect size d: 0.54). Among sensory components a marked reduction was found for the experience of thermal pain. A statistically and clinically reliable change was assessed in 18% of he RA-patients, further 26% indicated a statistical only change. 33% remained stable at a functional level of pain experience. 12% did not change a high level of pain, and 11% deteriorated. Change in the coping behaviors of avoidance and support were associated with success in pain reduction.
  
  
  CONCLUSIONS
  In the assessment of patient improvement different qualities of pain experience should be taken into account. It was suggested that inpatient multidisciplinary treatment was beneficial with regard to pain reduction in nearly on half of the RA-patients. The coping behaviors of avoidance and social support deserve attention as pain change associated variables.
