Description:

This prospective observational study enrolled adult volunteers for a sleep quality research study through a questionnaire survey distributed via a WeChat two-dimensional code from May 2021 to April 2022. Participants were exposed to flicker stimulation through a light and sound device for a duration of 8 weeks with daily monitoring. A total of 37 participants underwent polysomnography (PSG) prior to the commencement of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Treatment adherence rate	Participants adhered well to flicker therapy over eight weeks, as measured by the percentage of days they used the device out of the total days they were assigned to use it.; Treatment adherence rate = days the patient completed treatment on time/56 days×100%	8 weeks (56 days)
Primary	Patient treatment adherence rate	Participants adhered well to flicker therapy over eight weeks, as measured by the percentage of days they used the device out of the total days they were assigned to use it.; Patient treatment adherence rate = sum of all treatment adherence rates / number of patients participating in treatment×100%	8 weeks (56 days)
Primary	Incidence rate of adverse reaction	Describe the specific situation of adverse reactions, including types, frequency, severity, and whether they have been relieved.; Incidence rate of adverse reactions = number of people experiencing adverse reactions/total number of people participating in treatment x 100%	8 weeks
