Research has underpinned Singing for Snorers from the start
and continues to be actively pursued to provide independent validation of the effectiveness of the exercises
in addition to positive feedback from customers.

Pilot study:

The first pilot study of singing exercises to reduce snoring was conducted by Alise Ojay at the Department of Complementary Medicine, University of Exeter in 2000.

The results suggested that singing exercises could indeed be used to reduce snoring:

Clinical Trial at Royal Devon & Exeter Hospital, UK:

The first clinical trial of Singing for Snorers was published in May 2013.

This trial was a randomised controlled trial using the Singing for Snorers exercises with two patient groups: patients with mild to moderate sleep apnoea and patients with a chronic snoring problem. The trial was based at the Department of Otolaryngology, Head and Neck Surgery, Royal Devon & Exeter NHS Foundation Trust Exeter, UK.

The author of the paper, Consultant Otolaryngologist Malcolm Hilton BM BCh FRCS, reports that there was a statistically significant reduction in daytime sleepiness and frequency of snoring after three months intervention using the Singing for Snorers exercises.

The paper states:

"In conclusion, this study adds weight to the hypothesis that improving the tone and strength of pharyngeal muscles reduces the severity, frequency and loudness of snoring, and improves mild to moderate sleep apnoea. The intervention has been applied to a study population which accurately reflects a cross section of patients presenting to secondary care in the UK with difficulties due to snoring, and has no adverse effects. In the context of other treatments which are more invasive, and may be poorly tolerated and painful, it should be considered as an alternative modality of treatment. Further studies in specific patient groups are needed to define the magnitude of effect."

Alise says:

I am very pleased that this trial measured a significant reduction both in daytime sleepiness and frequency of snoring for individuals described in the paper as representing "a cross section of patients presenting to secondary care in the UK". These patients all followed the Singing for Snorers CD programme on their own, and their only support was a single brief phone call to answer any questions.

This positive result is all the more significant given that this was an 'intention to treat' trial: which means that once participants agree to take part their results are included regardless of whether they actually try the treatment under investigation. So, even though three of the experimental group reported not doing the exercises, all the participants who completed the questionnaires, regardless of their level of adherence to the programme were included in the final result.

This trial did not receive any funding and therefore questionnaires were used rather than before and after sleep studies. Sleep studies, of course, would have been preferable, however the questionnaires used have been subjected to research and as a result are validated and considered reliable within the medical field.

The paper notes that further studies of specific patient groups are needed to identify those most likely to benefit from the programme. Medical clinicians interested in following up this trial are warmly invited to make contact.
