About this study
Official title: THE EFEECT OF USING LOW LEVEL LASER THERAPY VS EXERCISES IN TREATMENT OF SNORING IN SLEEP APNEA 'S PATIENTS
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
Read the detailed description
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
- Conditions
- Obstructive Sleep Apnea, Snoring
- Being tested
- low level laser therapy, oropharyngeal exercises
- Medical subject headings
- Sleep Apnea, Obstructive, Snoring
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
low level laser therapyDevice
laser applications to the oral mucosa and soft palate tissue
oropharyngeal exercisesBehavioural
structured myofunctional and tongue strengthening exercises for snoring reduction
| Study group | Role | What they receive |
|---|---|---|
| laser therapy group | Experimental | patients in this group received low level laser therapy targeting soft palate and surrounding upper airway tissues Receives: Device: low level laser therapy |
| orophrgeal exercises | Experimental | patient in this group performed oropharyngeal exercises and tongue exercises to strengthen upper air way Receives: Behavioral: oropharyngeal exercises |
| control group | No intervention | patient in this group didn't receive any active exercises or laser they receive only advices |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: 6 weeks
