NCT00936286

Brief Summary

The purpose of this study is to determine whether respiratory muscle training by means of normocapnic hyperpnea leads to clinical and polysomnographical improvements in patients with mild to intermediate sleep apnea syndrome.

Respiratory Muscle Training

EXPERIMENTAL
Device: SpiroTiger

Interventions
