Respiratory Function and Dyspnea in Fibromyalgia Syndrome

Abstract

Objectives: To evaluate the presence of dyspnea and its association with the pulmonary function test or any other clinical parameters in patients with fibromyalgia syndrome [FMS].Methods: Thirty-five females satisfying the American College of Rheumatology criteria for FMS and 20 healthy controls were included in this study. A history of dyspnea was obtained and classified into five grades according to the World Health Organization's [WHO] dyspnea classification. Spirometric pulmonary functions were measured in each subject including forced vital capacity, forced expiratory volume in one second, peak and forced expiratory and inspiratory flow, and maximum voluntary ventilation.

JOURNAL OF MUSCULOSKELETAL PAIN 8Results: Patients with FMS and controls did not differ in age and body mass index. Dyspnea was the fifth most common associated symptom and found in 57.1% of the patients. Spirometric values were normal among patients and controls, and the differences in pulmonary functions between patients and controls were not statistically significant [P > 0.05]. There was a statistically significant positive correlation between pain score measured by visual analog scale and the WHO dyspnea grade [R = 0.532, P < 0.001]. The WHO dyspnea grade was also found to be correlated positively with chest pain [R = 0.464, P < 0.005].Conclusions: Dyspnea is a common symptom in patients with FMS and is not explained by pulmonary causes, but may partly be due to chest wall discomfort and pain intensity. Understanding the cause of this symptom in FMS may help in the management of these patients who are suffering from dyspnea.

Lung Function, Respiratory Muscle Strength, and Thoracoabdominal Mobility in Women With Fibromyalgia Syndrome

“…4 Thus, the presence of pain in regions related to respiratory mechanics and the presence of symptoms, such as dyspnea and fatigue, have drawn attention to the respiratory evaluation in women with FMS. [5][6][7][8][9][10] However, the results are still incipient, and some of them are contradictory. Kesiktas et al 10 reported an obstructive respiratory pattern in women with FMS, due to the lower values of FEV 1 and FEV 1 /FVC.…”

Respiratory Function Analysis in Patients with Chronic Pain: An Umbrella Review and Meta-Analysis of Pooled Findings

“…From the SRs conducted by López de Uralde Villanueva et al [15] and Kahlaee et al [18] in patients with CNP, the following primary studies were extracted: [33][34][35][36][37][38][39][40]. The following primary studies were extracted from the SRs conducted by Ortiz-Rubio et al [16] in patients with FMS: [41][42][43][44][45]. Finally, only two primary studies were extracted from the study by Abdollahzadeh and Abbasi [17] in patients with CLBP [46,47], because they were the only ones that adhered to the aim of this umbrella review.…”
