About this study

Official title: Functional MRI Study of the Effects of Vibrotactile Sensory Stimulation on Brain Activity in Fibromyalgia Patients

The purpose of this study is to investigate the effects of low-intensity and prolonged vibrotactile sensory stimulation on brain activity and functional connectivity in fibromyalgia patients.

Being tested

What participants receive

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

  • Vibrotactile stimulationDevice

    The active treatment will involve whole-body sensory stimulation with mechanical stimuli of vibrotactile (pallesthetic) type at a relatively high rate, low intensity and long duration administered at sleep time (a total daily duration of 3 h distributed within a period of 2 h at bedtime and 1 h prior to getting up). The intensity will be 30% of power at bedtime and 45% prior to getting up.

Study groups in NCT03785535
Study groupRoleWhat they receive
Actual treatmentExperimentalVibrotactile sensory stimulation will consist on whole-body stimulation with mechanical stimuli of pallesthetic type at high rate (2-90 Hz), low intensity and long daily duration (3h).
Receives: Device: Vibrotactile stimulation
ShamSham comparatorSham treatment will be applied using identical instruments and with power and duration programmed identically. However, in this case, the output will not be the signal activating the vibration motors, but rather an electrical signal turning on an incorporated pilot light indicating that the (simulated) treatment was operating
Receives: Device: Vibrotactile stimulation

What is being measured

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

  1. Functional MRI measures of brain functional connectivity. A correlation scale ranging from 0 to 1 will be used.

    Change on brain activity rated using functional MRI measures of functional connectivity

    Measured: 3 weeks

  2. Functional MRI measures of brain activity. A functional MRI signal change scale ranging from 0 to 1 will be used.

    Change on brain activity rated using functional MRI measures of brain activation in response to nociceptive stimulation

    Measured: 3 weeks

Secondary outcomes (3)
  1. Functional MRI measures of sensory system activity. A functional MRI signal change scale ranging from 0 to 1 will be used.

    Change on brain activity rated using functional MRI measures of brain activation in response to non-nociceptive stimulation

    Measured: 3 weeks

  2. Measured fibromyalgia symptoms using a 101-point numerical rating scale.

    Change on fibromyalgia symptoms (including pain, fatigue, cognitive symptoms, sleep disturbance, and general health rating). Rated using Numerical Rating 101-point Scales.

    Measured: 3 weeks

  3. Tolerability rated using a numerical rating scale ranging from 0 to 100 points.

    Tolerability index (0-100).

    Measured: 3 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Vibrotactile stimulation in people with Fibromyalgia, run by Neurovoxel SLP at 1 site in Spain.

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 5 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 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 Spain. 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?

Functional MRI measures of brain functional connectivity. A correlation scale ranging from 0 to 1 will be used. (time frame: 3 weeks). The study lists 2 primary outcomes in all. 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 3 Mar 2021.
