Training to strengthen breathing muscles in people with obstructive sleep apnea

Effect of Inspiratory Muscle Training on Daytime Sleepiness in Obstructive Sleep Apnea Syndrome : Prospective Randomized Controlled Trial

Not applicable Interventional Centre Hospitalier Régional d'Orléans · NCT06117579

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.

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.

Who should consider this trial

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.

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.

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 performed: 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.
