An interventional study of low level laser therapy and oropharyngeal exercises in Obstructive Sleep Apnea and Snoring, sponsored by Cairo University. Completed at 1 site in Egypt. Open to participants aged 40 Years to 55 Years. Per ClinicalTrials.gov, last updated 2026-06-25.
Sponsored by Cairo University · Not applicable, Interventional, and Treatment
the purpose of this study is to evaluate and compare the effectiveness of using low level laser therapy versus oropharyngeal exercises in the treatment of snoring in patient diagnosed with obstructive sleep apnea.
the study aims to determine which intervention provide better clinical outcome in reducing snoring severity and improve sleep quality
patients participating in this study were randomly allocated into parallel group to evaluate the therapeutic effects on snoring . one group received low level laser therapy targeting soft palate while second group received oropharyngeal and tongue exercises to strengthen upper air way muscles the treatment outcome were evaluated before and after the intervention period . the primary clinical assessment for snoring risk and severity was conducted using berlin questionnaire .
statistical analysis was performed to compare the pre and post treatment result between the groups to identify the most effective non invasive treatment modality for snoring in sleep apnea patients

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

snoring severity and risk using the berlin questionnaire
the Berline questionnaire is used to assess the risk and severity and obstructive sleep apnea .it consist of 3 categories addressing the severity of snoring, day time sleepiness, and history of high blood pressure or obesity changes in the questionnaire scores will be evaluated to compare the clinical outcome between the groups
