What does low psychological distress mean in patients with no mental disorders and different pains of the musculoskeletal system?

Objectives: The aim of this study is to define the different levels of psychological distress in patients suffering from pain and functional disorders of the musculoskeletal system. Methods: This investigation was conducted as a retrospective study of 60 patients randomly selected of a German specialized orthopaedic hospital within the year 2016, whose therapeutic approaches are based on a non-surgical orthopaedic multimodal approach of manual therapy. All patients were suffering from pain and functional disorders of the musculoskeletal system. Two groups were formed: one without and one with additional mental disorders according to ICD-10. The impairment score (ISS) according to Schepank was determined. Results: The somatic sub score of the ISS was the highest sub score in both patient groups. The cumulative value of the ISS score of patients with both a mental disorder and pain in the musculoskeletal system was higher than for patients without concomitant mental disorder. For patients without concomitant mental disorder, the cumulative ISS exceeded the test criteria for mentally healthy individuals. Conclusions: Patients without mental disorder but with chronic pain of the locomotoric system receive a psychological pain management program, as it is part of the billing code OPS 8-977 to the health insurance companies in Germany. However, the data show that these patients also have a substantial somatic subscore and a cumulative ISS above the level of healthy individuals. The absence of psychological disorders (according to ICD-10) in patients with pain of the musculoskeletal system should not lead to the assumption that these patients are psychologically inconspicuous. Subsyndromal mental findings (below ICD-10) can be one aspect of a mental disorder presenting with primarily somatic symptoms. In this case, patients would benefit from a psychotherapeutic program in a similar way as the patients with mental disorders according to ICD-10.
