Comparing the Sunrise jaw‑movement wearable with oximetry and WatchPAT for diagnosing obstructive sleep apnoea

Sunrise in Obstructive Sleep Apnoea Study (SOSA) A Comparison of the Sunrise Mandibular Movement Monitoring Device With Overnight Oximetry and WatchPAT in the Diagnosis and Management of Obstructive Sleep Apnoea.

Not applicable Interventional Manchester Metropolitan University · NCT07269483

This will test whether the Sunrise jaw‑movement wearable can help diagnose obstructive sleep apnoea in adults referred to an NHS sleep clinic by comparing it with overnight oximetry or the WatchPAT device.

What this trial studies

Adults referred with suspected obstructive sleep apnoea will use the Sunrise jaw‑movement wearable at home for one night at the same time as their usual diagnostic test (overnight oximetry or WatchPAT 300). Researchers will compare how often the different tests lead to a definitive management decision (start treatment, discharge, need more testing, or schedule a clinic appointment), plus time to decision and patient experience. The device has prior validation against full polysomnography with reported high accuracy, and this study embeds the device into an existing NHS diagnostic pathway to test real‑world performance. The study also seeks to include patients of diverse ethnic backgrounds to address gaps noted in guidance about device accuracy across skin tones.

Who should consider this trial

Good fit: Adults (≥18 years) referred with suspected obstructive sleep apnoea who can give informed consent, have a smartphone with Bluetooth/WiFi to run the Sunrise app, and can follow English or picture‑guided instructions are eligible.

Not a fit: Patients with suspected non‑OSA sleep disorders, chronic hypercapnic respiratory failure, unstable cardiovascular disease, non‑arteritic anterior ischaemic optic neuropathy, or those without smartphone/internet access are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, Sunrise could speed up and simplify home testing for OSA, leading to faster treatment decisions and a better patient experience.

How similar studies have performed: Previous validation studies comparing Sunrise to full polysomnography reported around 88–100% accuracy depending on severity and a 92% accuracy in one comparison, so the device has supportive evidence though pathway integration is less studied.
