| Measure | Time frame |
|---|---|
| The primary outcome of this study is the change in the Apnoea–Hypopnoea Index (AHI) and related sleep parameters after the use of a tongue stimulator device for 4 weeks.This includes improvement in respiratory disturbance events, oxygen desaturation parameters, snoring duration, and subjective sleepiness.The main hypothesis is that daily neuromuscular electrical stimulation of the tongue will reduce the severity of obstructive sleep apnoea and improve sleep quality. Timepoint: * Baseline (Week 0): Before starting the intervention (initial PSG and questionnaires).* Post-intervention (Week 4): After 4 weeks of daily tongue stimulator use (repeat PSG and questionnaires). Method of measurement: The Apnoea–Hypopnoea Index (AHI), mean oxygen saturation (SpO2), Oxygen Desaturation Index (ODI), and total snoring time will be measured by full-night attended polysomnography (PSG NO.4) using a sleep monitoring system.Subjective sleepiness and sleep quality will be assessed using validated questionnaires:* Epworth Sleepiness Scale (ESS)* Pittsburgh Sleep Quality Index (PSQI) All measurements will be performed by a sleep technician blinded to group allocation. | — |
