The Role of Resilience for Physical Functioning of Patients With Fibromyalgia Syndrome Using the 6-Min Walk Test

Fibromyalgia (FM) is a prevalent chronic pain disorder, characterized by widespread musculoskeletal pain and fatigue that is associated with significant functional limitations. Its mechanisms are only partially understood. The investigators hypothesize that physical functioning (as measured by the 6-Min Walk Test) of FM patients and healthy controls is negatively influenced by resilience and pain sensitivity. The investigators will perform a case control study to test our hypothesis within and between groups.
