Summary

Fibromyalgia syndrome is characterized by chronic pain, fatigue, sleep problems and functional symptoms. Fatigue, anxiety and depression disorders, poor quality of life, sleep disorders, decreased concentration, and impaired cognitive functions are non-specific pain-related symptoms. Various studies have reported decreased chest expansion, maximal ventilatory volume and maximal expiratory pressure in fibromyalgia patients with widespread body pain. Additionally, dyspnea is a symptom associated with respiratory muscle weakness and is associated with general fatigue. In these individuals, lower data are obtained in daily living activities and general health evaluation surveys. We did not find any study in the literature regarding the relationship between diaphragm thickness and fibromyalgia symptoms. In the light of these data, we aimed to evaluate the thickness of the diaphragm, one of the most important inspiratory muscles, in fibromyalgia patients.

Detailed description

Demographic information of all individuals included in the study will be collected. Daily living activity will be evaluated with Short Form-36 (SF-36), Fibromyalgia Impact Questionnaire (FIQ), Pittsburgh Sleep Quality Questionnaire (PSQI) and Beck Depression Inventory. In order to evaluate the respiratory function test in both the fibromyalgia and control groups, three consecutive measurements will be taken with a hand spirometer and the arithmetic average of these three measurements will be recorded. In fibromyalgia and control patients, diaphragm thickness was measured at 8-9 degrees on the right anterior axillary line with a 6-14 Mhz linear, conventional ultrasound probe (Mindray DC-8, Shenzen Mindray Bio-Medical Electronics CO. LTD., P.R. China) in the supine position. It will be measured at the end of inspiration and expiration from the intercostal space. Three measurements will be made and the arithmetic average will be evaluated.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Fibromyalgia study form	Fibromyalgia study form, consisting of clinical measurement, Fibromyalgia impact questionnaire (FIQ), Beck Anxiety Questionnaire and Beck Depression Questionnaire, Short-Form (SF)-36, who applied to the outpatient clinic with fibromyalgia will be filled in detail.
DIAGNOSTIC_TEST	Pulmonary function test	Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders. The investigators will use handheld spirometry device for measurement. Three measurements will be made. In these three measurements; FEV1(Forced Expiratory Volume In One Second)(L), FEV1 (%predicted), FVC (Forced Vital Capacity) (L), FVC (%predicted), FEV1/FVC (%) and FEV1/FVC (%predicted) will be evaluated. The arithmetic average of the results of these three measurements will be taken.
DIAGNOSTIC_TEST	Ultrasonographic Diaphragm Thickness Measurement	Diaphragm thickness (millimeter-mm) will be measured in the supine position with a 6-14 Mhz lineer, conventional ultrasound probe (Mindray DC-8, Shenzen Mindray Bio-Medical Electronics CO. LTD.,P.R. China) at the end of inspiration and expiration from the intercostal space on the anterior axillary line. The measurements will be evaluated by making three measurements from the right 8-9. intercostal space where the diaphragm is best visualized. End-expiratory (Forced residual capacity-FRC) (millimeter-mm), end-inspiratory (Total Lung Capacity) (millimeter-mm) and thickening rate (%) (thickness TLC / thickness FRC) will be evaluated three times and the arithmetic average of these three measurements will be taken.
