Study summary

A prospective, open, randomized, pilot clinical trial which aims the assessment of quality of life (QOL) in epilepsy outpatients equipped with a wrist-worn biosensor that provides measures of electrodermal activity and accelerometry. These measures are used to automatically detect epileptic seizures that are transmitted to a mobile phone-based system for alerts and recording.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    experimental group

    The experimental group will make use of the Alert app that sends alarms to patients mobile devices, and if desired to the mobile devices of their caregivers. This group will also use the Mate app which is used as a seizure diary

    Device: Embrace with Alert and Mate apps

  • Active comparator
    Control group

    The control group will only use the Mate app and not the Alert app. This group will thus not receive any notification, from the device, and will be unaware, of the devices performance

    Device: Embrace with Mate app only

Interventions

  • DeviceEmbrace with Alert and Mate apps

    Patients will wear the device on their wrist as often as possible during the day and night. The Embrace Watch contains sensors and memory recordings of electrodermal activity, temperature and physical activity from the wearer. This group will receive notifications on the mobile phone when seizure takes place. Quality of life questionnaires will be filled by the patients at the first follow-up and final assessments.

    Also known as: experimental group's intervention

  • DeviceEmbrace with Mate app only

    Patients will wear the device on their wrist as often as possible during the day and night. This group will just use the Mate app that summarizes Embrace Watch data for the owner and captures contextual information around events.This group will not receive any alert notification on the mobile phone when a seizure takes place.

    Also known as: Control group's intervention

What researchers measure

Primary outcomes

  1. The mean change from Baseline of the total score, of the french version of the Quality of life Epilepsy inventory-31

    The change between the QOLIE-31 questionnaire total score measured at the first and the final visit will serve as primary endpoint. The possible range of each scale's final score is from 0 to 100. higher scores reflect better quality of life.

    Time frame: 3 month

Secondary outcomes

  1. The mean change from Baseline of the total scores of seven Quality of Life in Epilepsy Inventory-31 subscales covering the following epilepsy-specific domains:

    Epilepsy-specific domains are: seizure worry, overall QOL, emotional well being, energy/fatigue subscales, medication effects, work-driving-social limits, cognitive function subscales. The possible range of each scale's final score is from 0 to 100. Higher scores reflect better quality of life.

    Time frame: 3 month

  2. Total number of true and false positives seizure detection

    Detected by the embrace device, saved via the alert app and controlled by the patient via the mate app

    Time frame: 3 month

  3. The usability total score of Embrace and Mate apps

    Will be assessed with the System usability scale (SUS). The score are to 0 from 100.

    Time frame: 3 month

  4. The utility total score of the system in general

    will be assessed via a structured questionnaire-based interview that was Tailored for this study

    Time frame: 3 month

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 22, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
