A theoretical framework to improve the construct for chronic pain disorders using fibromyalgia as an example

Area of Science:

• Pain Medicine
• Rheumatology
• Neuroscience

Background:

• Fibromyalgia (FM) presents as a frequent, complex chronic musculoskeletal pain disorder.
• Despite extensive research, FM lacks definitive biological correlates, resulting in an ill-defined clinical construct.
• Current understanding necessitates a re-evaluation of FM's underlying mechanisms.

Purpose of the Study:

• To critically review promising candidate biomarkers for Fibromyalgia.
• To propose a research agenda for developing a clearer construct of FM.
• To explore theoretical frameworks integrating biological and behavioral factors in FM.

Main Methods:

• Literature review of existing research on Fibromyalgia biomarkers.
• Critical analysis of candidate biomarkers and their potential utility.
• Development of a proposed research agenda and theoretical framework.

Main Results:

• Identification of promising, yet unconfirmed, candidate biomarkers for FM.
• Highlighting the need for research that moves beyond the illness-disease dichotomy.
• Emphasis on the reciprocal interactions between biological and behavioral factors.

Conclusions:

• A clearer construct of Fibromyalgia is achievable through focused research.
• Integrating biological and behavioral research is crucial for advancing FM understanding.
• This approach holds potential benefits for broader pain medicine and medical research.
