Phase II Study - Trial of a Phototherapy Light Device to Improve Sleep Health (PHOTONS)
1 de noviembre de 2021 actualizado por: MICHAEL A GRANDNER, University of Arizona
There are few devices currently on the market claiming to improve sleep.
This study will investigate the efficacy of phototherapy on improving sleep, in the form of a wearable neck device used at night.
Descripción general del estudio
Descripción detallada
This study will investigate the efficacy of phototherapy on improving sleep, in the form of a wearable neck device used at night.
Phototherapy has been shown to improve chronic pain, cerebral blood flow, neurological function, and capillary growth in skeletal muscle.
A device worn at night may improve sleep onset, total sleep time, or modify sleep architecture.
Improved cardiovascular function may facilitate a decrease in core body temperature needed for sleep onset.
Relaxation from direct heat may help to decrease cortisol levels, thus reducing the number of night-time arousals.
It may also decrease circulating levels of norepinephrine (NE), one of the main neurotransmitters involved in arousal.
The aim of this study is to evaluate if the device worn leads to greater next-day wellbeing and cognitive function as a result of increased slow-wave activity.

¿Qué mide el estudio?
Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Change in subjective rating of the device across a 3-week intervention
Periodo de tiempo: Change in subjective rating of the device from baseline (pre; Day 0) to after 21 days of wearing it (post)
|
There will be a subjective rating of the phototherapy device using a series of questions assessing device's effect on sleep and next-day function at the end of the trial.
|
Change in subjective rating of the device from baseline (pre; Day 0) to after 21 days of wearing it (post)
|
|
Change in Insomnia Severity Index (ISI) scores across a 3-week intervention
Periodo de tiempo: Change from baseline over the course of the study (after 21 days of wearing the device)
|
The ISI is a 7-item insomnia screening tool that is the gold standard for quantifying severity of clinical insomnia symptoms.
|
Change from baseline over the course of the study (after 21 days of wearing the device)
|
|
Change in objective sleep efficiency across a 3-week intervention
Periodo de tiempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Objective sleep efficiency will be measured with a wearable device (Oura ring) that is worn for the duration of the study and captures sleep and wake data using actigraphy.
|
Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Medidas de resultado secundarias

Periodo de tiempo |
|---|---|---|
|
Change in mean sleep latency assessed using sleep diaries
Periodo de tiempo: Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
Sleep latency, or time taken to fall asleep, will be assessed using morning sleep diaries completed by the participant upon awakening.
The mean sleep latency during the baseline period (pre) will be compared to after three weeks of wearing the phototherapy device (post).
|
Change from mean baseline period (first two weeks of wear) to post three weeks of wearing the phototherapy device.
|
|
Change in Karolinska Sleepiness Scale (KSS) score
Periodo de tiempo: Change from before intervention (pre) to post three weeks of wearing the phototherapy device (Day 21)..
