Mandibular Jaw Movement with the Sunrise device – Novel Parameters beyond home polygraphy (ID 656)
Sefam Medical Ltd
Abstract
Introduction:
Sunrise is a NICE guideline approved 3-gram CE marked sensor mounted on the chin during sleep. It measures mandibular jaw movements (MJM) via its embedded accelerometer and gyroscope that can detect sleep disordered breathing (SDB). It generates a automated report that provides novel parameters beyond the Apnoea Hypopnea Index (AHI). Sunrise measures: estimated AHI, Body mass index (BMI), Epworth Sleep Sale (ESS), Insomnia severity index (ISI), Total sleep time (TST), Sleep onset latency (SOL), Sleep efficiency (SE), Sleep Stages, Wake after sleep onset (WASO), Rhythmic masticatory muscle activity (RMMA), Respiratory effort (% of total sleep time) and sleep position among other sleep related metrics.
Methods: 25 adults referred from primary care with suspected SDB were included in this case series. Participants underwent a Sunrise test following a review by an Advanced Respiratory Nurse.
Results: 25 (18 males, 7 females) completed the Sunrise test. Among these, 65% (18/25) showed moderate to severe SDB, while 88% (22/25) were overweight. An ESS score of 11 or higher was observed in 40% (10/25). Additionally, 68% (17/25) reported possible comorbid insomnia. Elevated RMMA, (bruxism episode index, BEI >4), was seen in 92% (23/25), Respiratory effort burden exceeded 30% of TST in 84% (21/25) of the Sunrise tests.
Conclusion:
The high prevalence of obesity observed in this series highlights the key importance of weight management strategies. The high prevalence of Co-morbid insomnia and excessive Sleep bruxism in this series warrants further investigation. Elevated respiratory effort burden is linked to increased risk of Type 2 diabetes and hypertension . Respiratory effort burden is important due to its association with sympathetic overactivity and vascular changes common in sleep apnoea. Sunrise measures parameters beyond standard home polygraphy, providing advanced insights into SDB. By leveraging these insights, clinicians can potentially enhance and apply personalised treatment strategies for individuals with sleep-disordered breathing. Data collection is continuing to gather further real life insights of this technology. Sunrise can be deployed by mail at scale with remote review of the results, offering services the opportunity to streamline patient pathways and reduce waiting times for home sleep apnoea testing.
