Overview
Brief Summary
This study investigates the comparative effectiveness of Inspiratory Muscle Training (IMT) and Conventional Breathing Exercises (CBE) in managing symptoms of Obstructive Sleep Apnea (OSA) and hypersomnia (excessive daytime sleepiness).
ObjectiveTo evaluate and compare how IMT and CBE influence:
- Respiratory muscle strength
- Sleep quality
- Daytime sleepiness
- Severity of OSA symptoms
Methodology
-
Participants diagnosed with OSA and hypersomnia were randomly divided into two groups:
-
IMT Group: Performed resistance-based inspiratory muscle exercises using a threshold device.
-
CBE Group: Performed standard breathing exercises (e.g., diaphragmatic and pursed-lip breathing).
-
Duration: Typically 4–8 weeks of training.
-
Measurements: Apnea-Hypopnea Index (AHI), Epworth Sleepiness Scale (ESS), and maximum inspiratory pressure (MIP) were assessed before and after the intervention.
Results
-
Both groups showed improvements in sleep parameters and daytime sleepiness.
-
The IMT group demonstrated significantly better outcomes in:
-
Reducing AHI (indicating milder sleep apnea)
-
Improving inspiratory muscle strength (higher MIP)
-
Reducing ESS scores (less daytime sleepiness)
Conclusion
- Inspiratory Muscle Training is more effective than conventional breathing exercises in improving respiratory strength and reducing symptoms in patients with OSA and hypersomnia.
- IMT can be a non-invasive adjunct therapy to enhance functional outcomes in OSA patients, especially those intolerant to CPAP therapy.
