Functional capacity and muscle function in adults with obstructive sleep apnea

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study compares adults with obstructive sleep apnea to healthy controls to evaluate respiratory function, respiratory muscle strength and endurance, peripheral muscle strength, upper-extremity functional capacity, muscle oxygenation, and dyspnea. Participants aged 18 to 65 with OSAS confirmed by polysomnography and an AHI of 5 or more are assessed and compared to controls without OSAS. Measurements may include pulmonary function tests, muscle strength testing, and functional exercise capacity, along with assessments of muscle oxygenation and breathlessness. The study aims to identify how OSAS affects muscle performance and daily activity, informing potential targets for therapy or rehabilitation.
