Study Details

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.

Study Design

Enrollment
80 participants (estimated)

Arms

  • Arm: 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).
  • Arm: 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.
  • Arm: 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.
  • Arm: 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.
