Trial summary

Non Rapid Eye Movement (NREM) sleep parasomnias (sleepwalking and sleep terrors) are frequent and disabling sleep disorders characterized by arousal specifically from slow wave sleep (SWS) with dissociated brain activity that may be related to lower nociceptive state. Read more about this study

About this study

Official title: Objective Measures of Pain Sensitivity in NREM Sleep Parasomnia

Non Rapid Eye Movement (NREM) sleep parasomnias (sleepwalking and sleep terrors) are frequent and disabling sleep disorders characterized by arousal specifically from slow wave sleep (SWS) with dissociated brain activity that may be related to lower nociceptive state. The investigators recently reported frequent subjective complaints of chronic pain, migraine and headache during wakefulness in adult sleepwalkers. They also described frequent analgesia during severe and injuring episodes, suggesting a relationship between dissociated brain activity and nociceptive dysregulation. However, this study did not included objective nociceptive measures and the retrospective assessment of perceived pain during parasomnia episodes over a lifetime span might also introduce a recall bias.

The aims of the present study are to measure objective pain sensitivity in patients with NREM parasomnias and matched controls during 1) parasomniac episodes, 2) light NREM sleep and SWS, and 3) wakefulness.

Fifteen adults with severe NREM parasomnia and 15 age and sex-matched controls will be recruited. A 25 hours (8 AM to 9 AM) sleep deprivation protocol followed by auditory stimulations during SWS will be used to trigger parasomniac episodes. Thermoalgic stimulations of graduate intensity will be applied during wakefulness (8 PM) to determine the nociceptive threshold. During the recovery sleep following the sleep deprivation, the investigators will apply repeated subthreshold thermoalgic stimulations in NREM stage 2, SWS and triggered parasomniac episodes and report the behavioural/neurophysiologic nociceptive responses.

The investigators hypothesized a lower nociceptive threshold during wakefulness in sleepwalkers and a decrease of the arousabiliy during SWS and parasomniac episodes. This study may help to better understand the etiology and mechanisms underlying the clinical enigma of the nociceptive dysregulation in NREM sleep parasomnias.

What participants receive

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

  • Case InterventionOther

    24-hour sleep deprivation protocol, polysomnographic monitoring of the recovery sleep, triggering of parasomniac episodes by auditory stimulations, thermoalgic stimulation (Modulator Sensory Analyzer Thermal Stimulator®) during wakefulness, parasomniac episodes, NREM stage 2 ans SWS

  • Control InterventionOther

    24-hour sleep deprivation protocol, polysomnographic monitoring of the recovery sleep, thermoalgic stimulation (Modulator Sensory Analyzer Thermal Stimulator®) during wakefulness, NREM stage 2 ans SWS

What is being measured

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

  1. Percentage of neurophysiological arousal response within 5 seconds after a subthreshold thermoalgic stimulation applied during parasomniac episodes.

    Measured: within 5 seconds after stimulation

Secondary outcomes (3)
  1. Temperature of the thermoalgic stimulation during wakefulness associated with a nociceptive perception of 5/10 on a visual analogic scale

    Measured: on inclusion

  2. Minimal temperature of thermoalgic stimulations associated with a neurophysiological arousal response in NREM sleep stage 2

    Measured: within 5 seconds

  3. Nociceptive behavioural response

    Measured: within 5 seconds after a subthreshold thermoalgic stimulations applied during sleep and parasomniac episodes

Questions about this trial

What is this clinical trial studying?

A study testing Case Intervention in people with NREM Parasomnia and Sleepwalking, run by University Hospital, Montpellier at 1 site in France.

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 8 inclusion and 8 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: withdrawn, as of the sponsor's last update on 11 Jun 2018. 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 France. 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. 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 was withdrawn before enrolling participants, so there are no results.

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?

Percentage of neurophysiological arousal response within 5 seconds after a subthreshold thermoalgic stimulation applied during parasomniac episodes. (time frame: within 5 seconds after stimulation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Jun 2018.
