Estudo ergométrico comparativo entre indivíduos portadores de fibromialgia primária e indivíduos normais sedentários

Abstract

Fibromyalgia is a chronic pain syndrome characterized by generalized musculoskeletal pain that may result in physical inactivity and immobility, The present study has the goal to compare the responses related to the exercise testing parameters of sedentary patients with primary fibromyalgia and patients without patologies. Two groups of sedentary patients were tested in treadmill, Ellestad protocol: Group A (n = 12, mean age = 53,2 years, primary fibromyalgia), Group B (n = 20, mean age = 51,6 years, normal controls). lnterruption criteria for exercise testing were: maximum heart rate reached, physical exhaustion and pain.There were no references of chest pain, nor were observed ischemic changes or arrhythmias during the exam. Statistic testing was done with Student't - testo By comparing the results between groups A and B it was shown that the difference between maximalload and heart rate at the end of test was not significant. Group A interrupted the test earlier (2.1%), developing lower values for total work (21.1%), chronotropic reserve (11.2%), functional capacity (15.6%) and DSBP (15.8%). The electrocardiographic responses during exercise did not show evidences of ischemic response or left ventricular function deficit. The patients of group A presented functional capacity considerably lower than those of group B. The results suggest that the limitations observed are related to the musculoskeletal system.
