To improve the quality of medical care in the group of poststroke patients, we are planning to examine neurological patients in a rehabilitation clinic simultaneously with a non-contact method (Sleepiz One) and a standard diagnostic polygraphy measurement. This easy and comfortable pre-screening (Sleepiz One) should reduce the barrier for ward physicians to request a sleep study. The method could help to overcome the bottleneck of resource-intense procedures. It is simple to carry out and does not disturb the sleep of the patients.

The scoring is done according to the AASM Manual Version 2.6. Patients with a confirmed diagnosis will be informed about therapy options by a sleep physician and receive a recommendation for further therapy in the discharge letter from the rehabilitation clinic.

The goal of the study is then to evaluate if a non-contact method, the Sleepiz One, presents an opportunity for a fast and easy pre-screening during rehabilitation. Therefore, the precision of binary classification of subjects based on their sleep apnea severity (AHI >= 15) made by Sleepiz One will be compared to PG data manually scored by expert sleep scorers.
