The registry criteria, word for word
Show all 2 criteriaShow less
Who can take part
- Being between 18 and 65 years of age; Having a diagnosis of obstructive sleep apnea (OSA) confirmed by polysomnography; Having sufficient cognitive ability to understand and follow the test instructions; Having adequate shoulder range of motion to elevate the upper extremities above head level for performing the 6PBRT; Voluntarily agreeing to participate in the study and providing written informed consent
Who cannot take part
- Presence of neurological diseases that may significantly affect upper extremity function (e.g., stroke, multiple sclerosis, peripheral neuropathy); Severe orthopedic conditions limiting upper extremity movement (e.g., advanced shoulder pathology, recent surgery, severe contracture); Unstable cardiopulmonary conditions (e.g., recent myocardial infarction, decompensated heart failure, uncontrolled arrhythmia, acute COPD/asthma exacerbation); Acute infection, febrile illness, or severe clinical exacerbation within the last 4 weeks; Pain severe enough to interfere with the test or any clinical condition preventing the safe administration of the test

About the trial
What the trial wants to find out
Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder characterized by recurrent upper airway obstruction during sleep, leading to intermittent hypoxia and sleep fragmentation. In addition to its well-known cardiometabolic consequences, OSA may negatively affect functional capacity and daily activity performance. However, upper extremity functional capacity in individuals with OSA has not been adequately evaluated.

The 6-Minute Pegboard and Ring Test (6PBRT) is a functional test designed to assess upper extremity functional capacity during unsupported arm activity. Although the test has been widely used in respiratory diseases, its measurement properties have not yet been evaluated in patients with OSA.
The aim of this study is to investigate the validity and reliability of the 6PBRT in adults diagnosed with obstructive sleep apnea using polysomnography. Participants with OSA will undergo polysomnographic evaluation and complete the 6PBRT. Test-retest reliability will be assessed by repeating the test under the same conditions. The relationship between 6PBRT performance and polysomnographic parameters (AHI, ODI, minimum SpO₂ and T90) will also be examined. In addition, associations between 6PBRT performance and clinical scales such as the Epworth Sleepiness Scale and Functional Outcomes of Sleep Questionnaire will be analyzed.
The findings of this study are expected to provide evidence regarding the measurement properties of the 6PBRT in individuals with OSA and contribute to the clinical assessment of upper extremity functional capacity in this population.
The 4 groups in the trial
- Mild Obstructive Sleep Apnea
Adults diagnosed with mild obstructive sleep apnea based on polysomnography (Apnea-Hypopnea Index 5-14 events/hour). Participants will undergo assessment of upper extremity functional capacity using the 6-Minute Pegboard and Ring Test (6PBRT).
- Moderate Obstructive Sleep Apnea
Adults diagnosed with moderate obstructive sleep apnea according to polysomnography findings (Apnea-Hypopnea Index 15-29 events/hour). Participants will perform the 6-Minute Pegboard and Ring Test to assess upper extremity functional capacity.
- Severe Obstructive Sleep Apnea
Adults diagnosed with severe obstructive sleep apnea based on polysomnography (Apnea-Hypopnea Index ≥30 events/hour). Upper extremity functional capacity will be evaluated using the 6-Minute Pegboard and Ring Test.
- Healthy Control
Age- and sex-matched healthy individuals without a diagnosis of obstructive sleep apnea. Participants will undergo assessment of upper extremity functional capacity using the 6-Minute Pegboard and Ring Test.
