Disrupted sleep patterns and quality are characteristic of sleep disorders, and impact other areas of patient well-being, including their physical functioning. Wearable DHTs can detect unique functional changes associated with sleep disorders and changes associated with treatment interventions, providing quantifiable measures of participant behavior that is otherwise difficult to obtain.

Patients with sleep disorders such as narcolepsy and idiopathic hypersomnia (IH) experience excessive daytime sleepiness that significantly impacts their functioning and ability to perform everyday activities. Measuring daytime sleep using a wearable device provides critical insights into sleep/wake patterns that nighttime assessments may overlook. For individuals with sleep disorders such as narcolepsy, hypersomnia, or insomnia, the ability to continuously and objectively capture episodes of daytime sleep helps researchers better understand disease severity, treatment response, and the real-world impact of disrupted sleep regulation.
Actigraphy provides an effective, noninvasive way to measure circadian rest–activity patterns and sleep-wake behavior in people with sleep disorders. In conditions like narcolepsy and REM sleep behavior disorder, actigraphy reveals disrupted sleep continuity, increased daytime napping, and irregular sleep–wake cycles. By continuously capturing activity data, actigraphy enables objective insights into circadian rhythm disruptions and helps differentiate central disorders of hypersomnolence.
