About this trial
Primary aim of this study was to compare respiratory muscle strength, aerobic capacity, dyspnea, pulmonary function tests and fatigue values with healthy controls. The secondary aim was to evaluate the relationship between respiratory muscle strength and other parameters in these patients and to examine the factors that may affect respiratory muscle strength. Respiratory muscle strength, aerobic capacity, respiratory function tests and fatigue will be evaluated

Trial outcomes
Primary outcomes
Respiratory muscle strength assessment
Respiratory muscle strength will be assessed with an intraoral pressure gauge. These are the intraoral pressures measured at maximal respiration against a valve that closes the airways. When applying MIP, the patient is asked to perform maximal expiration. As a result, the patient is asked to maximally inspire against the closed airway and maintain this for 1-3 seconds. MEP, on the other hand, after maximal inspiration, the patient is asked to perform maximal expiration against the closed airway for 1-3 seconds.
Secondary outcomes
Aerobic capacity assessment
Aerobic capacity will be assessed using exercise testing. VO2max will be assessed using the Cosmed FitMate Pro® (Cosmed, Italy). The FitMate Pro® includes a turbine flowmeter to measure ventilation and a galvanic fuel cell oxygen sensor to analyze the oxygen fraction in expired gases.
Fatigue assessment
Fatigue will be assessed with the Fatigue Severity Scale (FSS), the Turkish validity and reliability of which was performed by Armutlu et al. This scale includes 9 questions related to fatigue.
Pulmonary function test
Pulmonary function test is routinely performed in Ssk patients. FEV1, DLCO and FEV1/FVC values will be recorded from the patients' files.
