Randomized Controlled Trial
Nasal dilator strip therapy for chronic sleep-maintenance insomnia and symptoms of sleep-disordered breathing: a randomized controlled trial.
To test the impact of nasal dilator strips (NDSs) on insomnia severity, sleep-disordered breathing (SDB) symptoms, sleep quality, and quality of life. Randomized, controlled trial of 4 weeks' duration. Community sample of nonobese, adults with a primary sleep complaint of chronic sleep-maintenance insomnia and mild to moderate SDB symptoms (treatment, n=42; control, n=38). ⋯ Significance was obtained for prospective sleep indices (p=0.01), retrospective, and prospective nonrestorative sleep ratings (p=0.003, <0.05), and retrospective sleep breathing symptoms (p=0.03). SDB education and NDSs demonstrated therapeutic efficacy in a select sample of insomnia patients with SDB symptoms. Replication of results requires placebo controls and objectively confirmed SDB cases.
