by Sunrise SA • Model: Sunrise SDDA / Sensor 2
The Sunrise Sleep Disorder Diagnostic Aid (SDDA) is an FDA-cleared home sleep test that measures mandibular jaw movements (MJM) to evaluate obstructive sleep apnea. By tracking changes in the trigeminal motor nucleus activity, it provides clinically validated data on respiratory effort, sleep staging, and True Sleep Time from a single point of contact on the chin.
Eligibility may vary by provider and plan. Check with your HSA/FSA administrator for specific details.
Evidence-based evaluation by medical professionals
"A breakthrough in patient comfort and diagnostic accuracy, utilizing unique mandibular motion signals to detect sleep-disordered breathing without chest belts or finger probes."
The Sunrise home sleep apnea test (HSAT) introduces a paradigm shift in diagnostics by focusing on mandibular jaw movements (MJM) as a proxy for respiratory effort. Traditional home tests often struggle with patient compliance due to uncomfortable wires, but Sunrise uses a single 3-gram sensor placed on the chin, which connects via Bluetooth to a smartphone app. This sensor tracks the trigeminal nerve drive, providing a high-fidelity look at how the brain regulates breathing during sleep. Landmark results from the SUNSAS trial demonstrated that the Sunrise diagnostic pathway can reduce the wait time for treatment initiation by more than 50% compared to traditional in-lab polysomnography (PSG). Beyond mere apnea detection, the device provides clinically validated sleep staging, respiratory effort-related arousals (RERAs), and differentiates between central and obstructive events. Its multi-night capability further enhances diagnostic confidence by capturing night-to-night variability.
