Fibromyalgia Syndrome in France: The Role of Assessment and Management of Sleep Disorders

The FIBOBS study is a multi-centered, observational, prospective study carried out within specialized chronic pain structures (CPS) in France. It will estimate the prevalence of sleep disorders, divided into three categories (poor quality of sleep in general, sleep apnea syndrome, restless legs syndrome), using self-questionnaires in patients with Fibromyalgia Syndrome (FMS) consulting within a CPS. The interaction between these sleep disorders and other symptoms of FMS will also be analyzed using self-administered questionnaires. Based on the hypothesis that sleep disorders associated with FMS are only imperfectly assessed and/or treated in CPS, the FIBOBS study will also interview pain physician in order to know both the diagnostic tools used and the recommended management when sleep disorders are suspected in the context of FMS. In addition, this study will provide a better understanding of the symptoms of FMS, their impact and how patients feel.
