The aim of the study is to investigate the relationship between central sensitization parameters and changes in static and dynamic balance in patients with fibromyalgia. The main questions it aims to answer are: * Do central sensitization parameters differ in patients with fibromyalgia compared to healthy individuals? * How is balance performance in these individuals compared to healthy controls? * Do central sensitization parameters affect static and dynamic balance in patients with fibromyalgia? * Do central sensitization parameters lead to quantitative changes in balance in patients with fibromyalgia?
