Functional health status was assessed with the Fibromyalgia Impact Questionnaire, pain intensity with Visual Analog Scale, central sensitization with Central Sensitization Inventory. Pearson's correlation coefficients were calculated to assess associations between reaction time and clinical and psycho-affective measures.
