Methods According to their MMPI profile out of a total of 24 patients, 12 patients were classified as 'psychologically abnormal'(at least one scale with a T-score higher than 70) and 12 as 'normal'. In a quasi-experimental setting, all patients underwent EMG-biofeedback therapy (12 sessions, twice weekly), after a waiting period of six weeks. Clinical symptoms (pressure point sensitivity, secondary symptoms), subjective pain dimensions as well as quality of life were assessed before and after the waiting period, immediately after the biofeedback training and at a three month follow up. Results Within the 'psychologically abnormal' patients primarily depressive, hypochondriacal and hysterical symptoms were found. Statistical evaluation showed that 'psychologically normal' patients experience long-term relief from pain measured in terms of pressure point sensitivity; vitality and mental health. 'Psychologically abnormal' patients, on the other hand, showed improvements in all the measured parameters (clinical symptoms, sensory and affective pain components, quality of life) after EMG-biofeedback. Long-term improvement, however, was observed only in pressure point sensitivity and the sensory pain dimension. Conclusion The results suggest, that assessment of FM-patients should not only consist of commonly used ACR diagnostic criteria but should also include psychodiagnostic criteria, as these may co-determine treatment outcome. One approach to treating FM patients with additional psychological abnormality might be combining EMG-biofeedback that enhances self-efficacy with psychotherapy that helps patients to become aware of their basic psychological problems.
