We used clinical measures, namely, Widespread Pain Index (WPI), Symptom Severity Scale (SSS), Fibromyalgia Impact Questionnaire\u2010Revised (FIQ\u2010R), Numerical Pain Rating Scale (NPRS), Central Sensitization Inventory (CSI), Pain\u2010Related Catastrophizing Thoughts Scale (PCTS), and functional measures, such as Sit\u2010to\u2010Stand (STS) test, and Timed Up and Go (TUG) test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The sample consisted of 91 participants divided into 3 groups: participants with KOA (<jats:italic>n<\/jats:italic>\u2009=\u200930), fibromyalgia diagnosed according to the ACR (FM\u2010ACR, <jats:italic>n<\/jats:italic>\u2009=\u200931), and fibromyalgia according to the medical diagnosis (FM\u2010Med, <jats:italic>n<\/jats:italic>\u2009=\u200930).
