Efficacy of Pulmonary Rehabilitation Program with Cycle Ergometer in Obstructive Sleep Apnea Syndrome

Background and objectives: Obstructive Sleep Apnea Syndrome (OSAS) is characterized by recurrent upper airway obstruction during sleep. The aim of this study was to investigate impact of respiratory rehabilitation program with cycle ergometer on exercise capacity, respiratory parameters, sleep and quality of life in OSAS. Patients and methods: Study population was consisted of mild and moderate OSAS patients aged 18-65. Controlled breathing techniques and respiratory muscle exercises were asked to practice 2 times a day for 10-20 minutes. Upperlimb muscles of the shoulder girdle and cycle ergometer exercise device consisting of aerobic exercise and resistance programs we implement, was performed 3 times a week for 50-60 minutes. Anthropometric measurements, respiratory function tests; exercise capacity, 6 Minute Walk Test; level of day time sleepiness the Ep worth Sleepiness Scale; sleep and quality of life, Functional Outcome of Sleep Questionnaire and the Short Form-36 Questionnaire; anxiety levels were assessed using the State-Trait Anxiety Inventory. Results: 40 patients were included in the study. After treatment, neck circumference, level of daytime sleepiness, resting and post-exercise heart rate and blood pressure response, dyspnea and leg fatigue decreased; and improved exercise capacity, MIP, quality of life and sleep were observed. Conclusion: PR may be an effective treatment option in patients with OSAS. To our knowledge this is the first report that demonstrating the effectiveness of cycling exercises on functional status, exercise capacity, life and sleep quality in patients with OSAS.
