Objective: To evaluate the efficacy of operant pain treatment for fibromyalgia syndrome (FMS) in an inpatient setting.
Methods: Sixty-one patients who fulfilled the American College of Rheumatology criteria for FMS were randomly assigned to the operant pain treatment group (OTG; n = 40) or a standardized medical program with an emphasis on physical therapy (PTG; n = 21). Pain assessments were performed before, immediately after, 6 months after, and 15 months after treatment.
Results: The OTG patients reported a significant and stable reduction in pain intensity, interference, solicitous behavior of the spouse, medication, pain behaviors, number of doctor visits, and days at a hospital as well as an increase in sleeping time. Sixty-five percent of the OTG compared with none of the patients in the PTG showed clinically significant improvement.
Conclusion: These results suggest that operant pain treatment provided in an inpatient setting is an effective treatment for FMS, whereas a purely somatically oriented program may lead to a deterioration of the pain problem.
