Usability and Stability of longitudinal at-home sleep evaluation using the Waveband EEG headband in an insomnia population

Abstract Study Objectives Sleep monitoring outside of clinics could enhance care for insomnia and other sleep disorders but requires home systems that are easily operable and provide consistent data quality over multiple nights. We assessed the Waveband for usability by participants and feasibility of obtaining multi-night sleep data in the home setting. Methods 15 subjects with insomnia wore the Waveband EEG headband and an FDA-cleared wearable home sleep testing device, WatchPAT ONE (“WP1”) for 3 nights. Usability was assessed via the System Usability Scale (SUS). Feasibility of participants to collect data was evaluated by examining stability of measured total sleep time in relation to measurements from the reference device (WP1) and data quality as evaluated by 3 human experts. Results Average SUS score was 69.7, meeting the 68-point threshold for good usability. Total sleep time recorded by the Waveband and WP1 devices showed a correlation of 87.3%. All the recordings had an average of over 7 scorable hours of data per night. Conclusions Waveband demonstrated good usability by patients, was operable by patients, and generated interpretable data that provided stable sleep estimates across nights, comparable to an established home sleep testing device. The device has potential to advance patient care, sleep research, and clinical trials by enabling longitudinal ambulatory sleep assessment.
