Effect of EMST Systemic Inflammation and Oxidative Stress in Patients With Moderate OSAS
- Conditions
- Obstructive Sleep ApneaOxidative StressRespiratory Muscle Training
- Interventions
- Other: Expiratory muscle trainig
- Registration Number
- NCT05242406
- Lead Sponsor
- Ahi Evren Chest and Cardiovascular Surgery Education and Research Hospital
- Brief Summary
It was aimed to investigate the effect of expiratory muscle strength training (EMST) applied at different intensities on systemic inflammation and oxidative stress in patients with moderate obstructive sleep apnea syndrome (OSAS). In the study, 32 male patients diagnosed with moderate OSAS will be included in the study. Participants will then be divided into 2 groups by block randomization. In the three-blind planned study; the first group will receive high-intensity %60 maximum expiratory pressure (MEP) EMST training, and the second group will be given low-intensity 30% of MEP, EMST training for 12 weeks. Disease-related symptoms, disease severity apnea-hypopnea index (AHI), oxidative stress index (OSI) and systemic inflammation level, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and fatigue severity will be evaluated before and after the study.
- Detailed Description
Primary outcome measures are; disease severity, oxidative stress index and systemic inflammation.
Secondary outcome measurements are; disease-related symptoms, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and severity of fatigue.

Group Intervention Description L-EMST Expiratory muscle trainig At 30% of the maximum expiratory pressure (MEP), 25 breaths, 7 days / week, a total of 12 weeks will be trained once a day with a 1-minute rest cycle in 5 breaths. Patients will be invited to control every 2 weeks. MEP measurements will be repeated and the training value will be adjusted in 30% of the new measurement. H-EMST Expiratory muscle trainig In 60% of the maximum expiratory pressure (MEP), 25 breaths a day, 7 days / week, a total of 12 weeks will be trained with a 1-minute rest cycle in 5 breaths. Patients will be invited to control every 2 weeks. MEP measurements will be repeated and the training value will be adjusted in 60% of the new measurement.
- Primary Outcome Measures
Name Time Method Disease severity 2 days Polysomnography recordings will be taken especially sleep efficiency and apnea-hypopnea index (AHI). Higher sleep efficiency and lower AHI values shows that patient have better status and lower disease severity
Oxidative stress-1 5 days TAS:Venous blood sample will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning after an overnight fast and will be analyzed with a colorimetric kit.
Systemic inflammation-1 5 days CRP:biochemistry laboratory will work on the Abbott Architect C4000 (USA) clinical chemistry autoanalyzer.
Systemic inflammation-3 5 days IL10:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.
Systemic inflammation-4 5 days IL-6:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.
Systemic inflammation-2 5 days TNF-a:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.
Oxidative stress-2 5 days TOS:Venous blood sample will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning after an overnight fast and will be analyzed with a colorimetric kit.
- Secondary Outcome Measures
Name Time Method Daytime sleepiness 2 days Epworth Sleepiness Scale . Minimum and maximum scores: 0-24. The higher Epworth Sleepiness Scale score means the higher that person's average sleep propensity in daily life , or their 'daytime sleepiness'
Exercise capacity 2 days 6 minute walking testing (6MWT):The primary outcome is the distance covered in meters or converted measure (such as feet) over 6 minutes. To measure functional aerobic capacity or general fitness, this test may be used in conjunction with VO2 testing.
Maximal inspiratory and expiratory muscle strength 2 days Maximal inspiratory and expiratory muscle strength will be evaluated with mouth pressure device.
Fatigue severity. 2 days Fatigue Severity Scale (FSS)Minimum and maximum scores: 0-7. FSS scores higher than 4 shows high intensity fatigue perception
Sleep quality 2 days The Pittsburgh Sleep Quality Index (PSQI). Minimum and maximum scores: 0-21. Higher PSQI scores show worse sleep quality.
