Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1) We will evaluate the EEG measurement device made by S'UIMIN Co., Ltd. in terms of wearability, effect on sleep, data characteristics in use environment, and signal-to-noise ratio. Furthermore, a performance verification test will be conducted by simultaneous measurement with PSG, and the characteristics and accuracy of each biological signal will be compared with the standard method to evaluate the equivalence. 2) Visual sleep staging will be performed by a clinical laboratory technician certified by the Japanese Society of Sleep Research after data acquisition of biometric information obtained from S'UIMIN's EEG measurement device and polysomnography EEG, electroretinogram, electromyogram, etc. collected during normal sleep and parameters such as lights-out time. The result is taken as the correct answer, and the judgment accuracy and agreement rate are calculated. 3) We will begin development of a program to automatically perform sleep staging by analyzing biopotential data such as EEG during sleep, referring to existing data from PSG tests and simple electroencephalographs. We will optimize the algorithm, the structure of the analysis system, and the analysis parameters, etc., in order to improve the judgment accuracy and agreement rate by comparing the analysis results of the program with those of clinical technologists certified by the Japanese Society of Sleep Research. 4) Once the judgment accuracy and agreement rate reach the target, optimize the algorithm, the structure of the analysis system, and the analysis parameters in order to improve the accuracy and agreement rate of the sleep staging judgment of the data acquired using the EEG measurement device manufactured by S'UIMIN Co. | — |

| Waking Sleep Awareness Questionnaire (MA version) At what time did you fall asleep last night? At what time did you wake up this morning? How many hours of sleep did you get last night? Example Entry date: Monday ID: I'm still tired I'm not tired Entry field 1. tiredness remains tiredness is gone 2. I have concentration I have no concentration 3. had a good sleep did not have a good sleep 4. feeling liberated feeling stressed 5. my body feels lazy my body feels crisp 6. have an appetite have no appetite 7. was out of bed a lot before falling asleep was out of bed a little before falling asleep 8. clear-headedness fuzzy-headedness 9. had many nightmares had no nightmares 10. had a good night's sleep had a bad night's sleep 11. felt uncomfortable felt refreshed 12. dreamed a lot dream a little 13. woke up a lot during sleep did not wake up during sleep 14. can answer a survey quickly now answering is troublesome 15. had a long sleep had a short sleep 16. slept lightly slept deeply | — |
