The use of telemedicine with a mobile application (MA) and wearable device (WD) for the management sleep disorders has recently received considerable attention. We designed an MA synchronizable WD insomnia treatment. Our pilot study determined efficacy simplified group cognitive behavioral therapy (CBT-I) delivered using our assessed participant adherence to satisfaction device.The CBT-I (CBT-I-MA) was by comparing variables (sleep efficiency [SE], Insomnia Severity Index [ISI], Pittsburgh...

Smartphones and wearable devices can be used to obtain diverse daily log data related circadian rhythms. For patients with mood disorders, giving feedback via a smartphone app appropriate behavioral correction guides could play an important therapeutic role in the real world.We aimed evaluate effectiveness of named Circadian Rhythm for Mood (CRM), which was developed prevent episodes based on machine learning algorithm that uses passive digital phenotype rhythm behaviors obtained activity...

A consistent diagnosis and classification system is important to ensure a good understanding of the pathophysiology ultimate treatment disorder. Insomnia one more common complaints encountered in outpatient setting. Despite prevalence insomnia, evaluation, treatment, research has been hampered by lack standard definition insomnia. In recent years, there have advances The ICSD-3 DSM-5 sleep-wake disorder classifications moved away from causal attributions that were inherent previous...

The circadian rhythm for mood (CRM) is a digital therapeutic, which aims to prevent episode and improve clinical course in patients with major disorders. Developed on the hypothesis of disorder, CRM predicts impending risk its built-in algorithm, utilizing wearable devices data daily self-reports, provides personalized feedback. In pilot study CRM, users experienced less frequent shorter duration episodes than non-users. To investigate efficacy upgraded double-blind, randomized,...

The Epworth Sleepiness Scale is a measure used for the diagnosis of sleep disorders including obstructive apnea (OSA) syndrome, insomnia, and narcolepsy. Although Korean version has been developed (the KESS), lifestyle such as floor culture low driving rates not considered. We aim to develop validate modified KESS (mKESS) that reflects lifestyle.The sample consisted 795 healthy participants 323 OSA patients. mKESS was by modifying several questions concern (questions 1, 2, 6, 7) (question...
