Personality construct as a biomarker in fibromyalgia: A narrative review from an autonomic rehabilitation perspective

BACKGROUND

The heterogeneity of symptoms and ineffective treatment raise questions about the current diagnostic criteria of fibromyalgia (FM). Misdiagnosis of FM often leads to less than efficacious treatment and poor quality of life.

OBJECTIVE

This article reviews relevant evidence-based literature on personality traits in FM patients with an autonomic dysfunction perspective based on a hierarchical model to explain the utility of considering the personality trait in FM diagnosis.

METHODS

A narrative review of articles concerning chronic pain, FM, and personality traits with respect to autonomic dysfunction in FM was conducted after extensive relevant literature searches.

RESULTS

Reports discussing the predisposing factors, including coping styles, anger, suicide risk, a lack of physical activity and social support, in maintaining persistent pain in FM exist. Relationships between pain duration and severity and personality traits like neuroticism and extraversion have been reported. Coexisting clinical manifestations of FM like sleep disorders, anxiety, and intestinal irritability indicate autonomic dysfunction.

CONCLUSIONS

This article lays out a constructive framework for individualized and personalized medicine for the effective rehabilitation of FM patients. The quest to find a definitive diagnosis of FM should include personality biomarkers that might translate into personalized medicine. An individualistic approach may bank upon artificial intelligence algorithms for both diagnostic as well as prognostic purposes in FM.

Physical activity in the treatment of fibromyalgia

International treatment recommendations for fibromyalgia (FM) highlight the importance of adapted physical activity (APA) combined with patient education. Cognitive and behavioral therapies as well as an interdisciplinary approach can be proposed for more complex or severe clinical situations, with a biopsychosocial vision of rehabilitation. To personalize the rehabilitation's therapeutic approach, a clinician can use simple and validated instruments for measuring physical performance that will highlight levels of physical conditioning, which range from low to very low in FM patients. Several systematic reviews and meta-analyses have found strong evidence that supervised aerobic and resistance-training programs reduce the pain intensity and significantly improve the quality of life and the physical and psychological functioning of female FM subjects. These therapeutic approaches appear safe and promising in terms of cost-effectiveness and should be the subject of more randomized controlled trials among male FM subjects and adolescents.

Body Reprogramming: Reframing the Fibromyalgia narrative and providing an integrative therapeutic model

We propose a theory known as the Hyland model to help conceptualise Fibromyalgia within a complex adaptive control system. A fundamental assumption is that symptom generating mechanisms are causally connected, forming a network that has emergent properties. An illness narrative has been developed which has a ‘goodness of fit’ with the lived experience of those with Fibromyalgia. The theory guides management within the clinical setting and incorporates current evidence-based therapeutic strategies, within a multi-modal intervention described as ‘Body Reprogramming’. This intervention focuses on non-pharmacological and lifestyle-based considerations. The theoretical framework also helps explain why modest therapeutic effects are gained from current pharmacological options.

What causes fibromyalgia? An online survey of patient perspectives

Fibromyalgia is a severe chronic pain condition that affects every aspect of life. Causes of the condition remain unclear, and quantitative research cannot account for patients' personal illness narratives and perceptions. This online survey gathered qualitative accounts of the perceived causes of their condition from 596 people with fibromyalgia, which were analyzed thematically. Themes were "Bodily assault, ill-health, and change"; "Emotional trauma and distress"; "Stress and vulnerability"; and "Explaining and authenticating fibromyalgia." Discussion focuses on the complexity of causation, the importance of understanding and having symptoms validated, and the potential for benefiting from patient expertise in building better practitioner-client relationships.
