Worldwide clinical studies

This was followed by a whole series of clinical studies around the world, which dealt with the training-related influence of snoring and nocturnal respiratory flow disorders and showed a positive effect of oral exercises on sleep-related breathing sounds and breathing stops (sleep apnea).

Original quotes from these papers:

  • Physical exercise is efficient in improving the quality of life in OSA patients,
  • Improvement in quality of life is comparable to that found with CPAP treatment,
  • Daytime sleepiness is reduced regardless type of physical exercise,
  • positively impacts severity of OSA can be measured.

Studies worldwide

USA 2018, Minneapolis, Minnesota
A “randomized double-blind” study (such a design represents the gold standard in medical research): the use of smartphones for exercise support was researched:

Smartphone-based delivery of oropharyngeal exercises for treatment of snoring: a randomized controlled trial

Output: After 8 weeks of training the participants showed a significant improvement of the snoring score, all sleeping partners reported a reduction of snoring in volume and extent.
