Validity and Reliability of the 6-Minute Pegboard and Ring Test (6PBRT) in Adults With Obstructive Sleep Apnea Syndrome

Plain-language summary
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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 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
Exclusion Criteria:
* 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
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
