Sleep Monitoring Clinical Trial
Official title:
Evaluation of the Ear-EEG System for Sleep Monitoring in Healthy Subjects
Verified date | May 2019 |

Is FDA regulated | No |
Health authority | |
Study type | Interventional |
Subjects sleep multiple nights in their own home, wearing actigraph, PSG (PolySomnoGraphy) and ear-EEG sensors. The object of the study is to determine the applicability of ear-EEG for sleep monitoring.

Primary | Cohens kappa | The test outcome is a set of matched polysomnography and ear-EEG sleep measurements. From this will be generated an algorithm for automatic sleep scoring based on ear-EEG (using leave-one-subject-out cross validation). The primary outcome measure of the test is the correlation between the automatically generated hypnograms and those generated manually from the scalp recordings. The accuracy is quantified using Cohen's kappa, which is a number between -1 and 1. An average (across all recordings) above 0.4 would be a success for the test. As the training of the sleep scoring algorithm requires large amounts of data, it is necessary to use a large number of subjects (20) to estimate the viability of automatic sleep scoring from ear-EEG recordings. This also means that kappa values are calculated for all recordings at once when the measurements are done. This method for creating sleep scoring algorithms and quantifying their success is in line with standard procedure in this field. |
