Summary

Fibromyalgia is a chronic pain disorder characterized by widespread pain and multiple systemic symptoms that negatively affect functional capacity. Although common symptoms and clinical features of fibromyalgia have been well described, the factors influencing functional capacity remain unclear. Therefore, this study aims to identify the determinants of functional capacity in patients with fibromyalgia.

Detailed description

Fibromyalgia is a chronic pain disorder characterized by widespread pain, fatigue, sleep disturbances, cognitive problems, and mood disorders, affecting 5% of the population, predominantly women. This condition lacks objective diagnostic markers and relies on subjective symptoms and tender points for diagnosis. The etiology of fibromyalgia, which involves biological, genetic, and environmental factors, remains unclear, making diagnosis difficult due to symptom variability and comorbidities. Pathophysiological mechanisms are not fully understood, leading to difficulties in diagnosis and treatment. Historically, fibromyalgia has evolved from terms such as 'neurasthenia' to 'fibrositis', and understanding has shifted from muscle inflammation to central nervous system dysfunction. The American College of Rheumatology criteria play a crucial role in diagnosing fibromyalgia, helping to reduce patient anxiety and unnecessary testing. In the literature, pain, fatigue, sleep problems, and trigger point sensitivity are among the symptoms frequently seen in fibromyalgia patients. Studies conducted on these symptoms indicate that patients particularly experience anxiety, depression, decreased functional capacity, decreased functional mobility, postural abnormalities, decreased respiratory and peripheral muscle strength, decreased physical activity, and difficulties in daily living activities. Although surveys conducted with fibromyalgia patients have identified symptoms, no studies have been found that examine the factors affecting functional capacity. Therefore, the aim of this study is to determine the factors affecting functional capacity in patients with fibromyalgia.
