Training to strengthen breathing muscles in people with obstructive sleep apnea
Official title: Effect of Inspiratory Muscle Training on Daytime Sleepiness in Obstructive Sleep Apnea Syndrome : Prospective Randomized Controlled Trial
Run by Centre Hospitalier Régional d'Orléans · NCT06117579 · Data updated 2026-11-12
This study is testing if a special breathing exercise program can help adults with obstructive sleep apnea feel less sleepy during the day and improve their breathing at night while using CPAP.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults over 18 years old diagnosed with obstructive sleep apnea and an apnea-hypopnea index of 5 or greater who require CPAP.
✕Probably not a fit
Patients with sleep apnea of neurological or mixed origin, those who cannot use CPAP, or individuals with cognitive disorders may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates the effects of inspiratory muscle training (IMT) on patients with obstructive sleep apnea (OSA), a condition characterized by interruptions in breathing during sleep. The research aims to assess whether IMT can improve the apnea-hypopnea index and reduce daytime sleepiness, thereby enhancing the quality of life for affected individuals. Participants will undergo a structured training program designed to strengthen the diaphragm and other respiratory muscles, potentially serving as an adjunct therapy to the standard continuous positive airway pressure (CPAP) treatment. The study will include adults over 18 years of age diagnosed with OSA who require CPAP.
Why it matters
Potential benefit: If successful, this approach could provide an effective complementary treatment for patients with obstructive sleep apnea, improving their overall quality of life.
How similar studies have gone: While inspiratory muscle training has been explored in limited studies, the efficacy of this specific approach in treating obstructive sleep apnea remains novel and untested.
