About this study

Official title: Development and Evaluation of a Cognitive-motor System for a Quantitative and Objective Measure of Fatigue in Functional MRI

The purpose of this study is to determine more objective, central and peripheral indices of fatigue state by exploring the neural and behavioral correlates of the alert process while keeping the idea to corroborate these results with those obtained during the performance of physical exercises and neuropsychological tests "classics" of attention, motivation, and functions evaluation. The interest of this study is to manipulate and compare the phasic and tonic alert mechanism through the activation of an extrinsic motivational system during fatigue. The investigators have chosen the alert since it is a basic cognitive process defined as the ability to increase attentional resources with the expectation of a target stimulus resulting in reduced response time. It can be phasic (extrinsic), favored by the presence of a warning signal preceding the target (preparation time) or tonic (intrinsic) occurring without warning signal (wakefulness). The evaluation of the alert is classically realized by a simple reaction time task with the presence or not of warning signal soliciting wether the tonic alert or the phasic alert.

The investigators suppose to revisit the healthy population with brain model alert issued in 2010 which highlighted the predominant role of the regions of the dorsolateral prefrontal cortex, parietal, cingulate and thalamus (non-motor) in maintaining attention and temporal preparation alert task.

The investigators identify also functional, motor and cognitive components of basal ganglia of thalamus. Cognitive-motor paradigm and neurological dysfunctions observed in multiple sclerosis population will help to identify and separate the cognitive role and motor brain regions, particularly the thalamus and basal ganglia. New neurological hypotheses are proposed

Read the detailed description

This project will be applied on healthy subjects, and the subject will be equipped with two electrodes attached to the muscle of the left arm (flexor) to measure muscle activity. That will be performed with a handgrip (the subject press on the handgrip).The subject will receive two sessions. It will conduct a trial session in the laboratory to control his ability to imagine the task (imagination run) and perform the driving task correctly.

Two saliva samples will be placed in tubes to be analysed to measure the concentration of cortisol before and after functional MRI. Then, psychological and satisfaction questionnaires will be completed by volunteers.

This protocol will then be adapted and transferred to multiple sclerosis population (in a second study), for which fatigue is one of the symptoms most commonly reported.

What is being measured

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

  1. Assessment of executive function and circuit of functional MRI

    Brain activity will be measured during tests to determine the central indices and peripheral quantitative and objectives of the state of fatigue.

    Measured: 1 day

Secondary outcomes (4)
  1. Muscle strength measured with the electromyogram data

    This outcome will be measured with the electromyogram data

    Measured: 1 day

  2. Saliva samples to measure the concentration of cortisol

    Samples will be placed in tubes to be analysed to measure the concentration of cortisol.

    Measured: 1 day

  3. Assess attentional and executive functions (questionnaires)

    Results of psychological (Mesulam, D2, Stroop) questionnaires

    Measured: 1 day

  4. Evaluation of voluntary satisfaction (questionnaire)

    satisfaction questionnaire

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Volunteer with MRI in people with Fatigue, run by Hôpital NOVO.

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 4 inclusion and 3 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 13 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Assessment of executive function and circuit of functional MRI (time frame: 1 day). 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 13 Feb 2017.
