Trial summary

Sleep, specifically deep sleep, plays a central role in healthy brain function, cardio-vascular processes, mood and quality of life. Auditory stimulation during one night of sleep has previously been shown to improve deep sleep and along with memory formation in both young and older adults. Read more about this study

About this study

Official title: Enhancement of Sleep Slow Wave Activity Using Wearable Auditory Stimulation Devices and Its Consequences on Daytime Functioning: a Randomized, Counter-balanced Crossover Study

Sleep, specifically deep sleep, plays a central role in healthy brain function, cardio-vascular processes, mood and quality of life. Auditory stimulation during one night of sleep has previously been shown to improve deep sleep and along with memory formation in both young and older adults. Yet, it remains unclear whether long-term auditory stimulation considerably improves sleep quality over longer time periods and how it affects daytime functioning such as cognition, mood, quality of life and peripheral functions (e.g. cardio-vascular). Due to the importance of deep sleep for brain and body and the presence of many conditions that involve reduced deep sleep (e.g. ageing) assessing the beneficial impact of long-term sleep enhancement and its consequences is of central interest.This study will assess the effect of auditory stimulation over two weeks (interleaved with a two weeks washout period) in a cohort of healthy young and older adults using portable recording and stimulation devices.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Application of tonesDevice

    During NREM sleep, tones (max. 60 dB) will be played using a portable, safe, in-home device. This device records biosignals (e.g. brain activity) and precisely times the tones during NREM sleep. It was developed and produced by the ETH Zurich and approved for use in this study by Swissmedic

  • No application of tonesDevice

    This is the sham-control intervention; The device will only record biosignals but will not play tones.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sleep quality

    Objective information about sleep macro- and microstructure will be assessed including measures like sleep architecture, amount of slow wave activity (SWA), amount of spindles, awakenings during sleep, and sleep fragmentation. In addition, subjective sleep quality will be obtained by questionnaires every morning over the intervention period. These measures will show whether auditory stimulation enhanced overall sleep quality compared to sham.

    Measured: From baseline period to study completion, assessed up to 2 months

Secondary outcomes (6)
  1. Daily functioning - Mood

    Mood will be digitally assessed using a daily mood scale over the intervention period

    Measured: From the beginning of the first intervention period until the end of the second intervention period, assessed within a time period up to 6 weeks

  2. Daily functioning - Quality of life

    Quality of life will be assessed using a World Health Organization (WHO) quality of life assessment before and after each intervention period

    Measured: From the beginning of the first intervention period until the end of the second intervention period, assessed within a time period up to 6 weeks

  3. Daily functioning - Vigilance

    Vigilance will be assessed using a digital psychomotor vigilance task, assessed daily over the intervention period

    Measured: From the beginning of the first intervention period until the end of the second intervention period, assessed within a time period up to 6 weeks

  4. Daily functioning - Cognition

    Cognition will be assessed using a digital test battery before and after each intervention

    Measured: From the beginning of the first intervention period until the end of the second intervention period, assessed within a time period up to 6 weeks

  5. Physiological parameters - Cardiovascular

    R-R interval based assessments will be obtained using wearable monitors

    Measured: From baseline period to study completion, assessed up to 2 months

  6. Physiological parameters - Physical activity

    Physical activity levels will be obtained using wearable monitors

    Measured: Through study completion, approximately 2 months

Questions about this trial

What is this clinical trial studying?

A study testing Application of tones and No application of tones in people with Sleep, run by Swiss Federal Institute of Technology at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sleep quality (time frame: From baseline period to study completion, assessed up to 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03420677, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2021.
