Didgeridoo playing as alternative treatment for obstructive sleep apnoea syndrome: randomised controlled trial

Snoring and obstructive sleep apnoea syndrome are two highly prevalent sleep disorders caused by collapse of the upper airways.1 2 3 The most effective intervention for these disorders is continuous positive airway pressure therapy, which reduces daytime sleepiness4 and the risk of cardiovascular morbidity and mortality in the most severely affected patients (apnoea-hypopnoea index (measured as episodes per hour) > 30).5 For moderately affected patients (apnoea-hypopnoea index 15-30) who complain about snoring and daytime sleepiness, however, continuous positive airway pressure therapy may not be suitable and other effective interventions are needed.1 6 7
