Trial summary

Rationale: The representation of the breast on the somatosensory cortex has not been precisely located. Therefore, a pilot study with healthy subjects is needed to localize the sensibility of the breast on the somatosensory cortex with the use of a 7 Tesla fMRI. Read more about this study

About this study

Official title: The Representation of the Sensibility of the Breast on the Somatosensory Cortex Using 7 Tesla fMRI: A Pilot Study

Rationale: The representation of the breast on the somatosensory cortex has not been precisely located. Therefore, a pilot study with healthy subjects is needed to localize the sensibility of the breast on the somatosensory cortex with the use of a 7 Tesla fMRI.

Objective: To determine the exact localization of the representation of the sensibility of the breast and nipple-areola complex on the somatosensory cortex. Secondly, to assess whether there are differences in representation between individuals of the same sex and between both sexes.

Study design: A single center pilot study carried out in the Maastricht University Medical Center, the Netherlands.

Study population: A total of 10 female and 10 male healthy individuals will be recruited.

Intervention: Every subject will undergo a functional MRI scan with stimulators applied to the bare breast in a fixed pattern. These stimulate the skin and sensory nerves of the breast and nipple-areola complex in a random sequence.

Main study parameters: The hemodynamic response after stimulation of the skin of the breast and nipple-areola complex, representing neuronal activity in that region, is measured. Within the somatosensory cortex (S1 and S2), the temporo-spatial brain activity patterns after the various stimulation conditions are assessed, and the representation of the breast on the somatosensory cortex is mapped.

What is being measured

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

  1. Changes in the blood oxygen level dependent (BOLD) contrast as a function of vibrotactile stimulation of the breast and nipple-areola complex

    Changes will be analysed using multi-voxel pattern analysis to localize the different parts of the breast in the somatosensory cortex.

    Measured: 90 minutes

Secondary outcomes (2)
  1. Changes in the blood oxygen level dependent (BOLD) contrast as a function of vibrotactile stimulation of the breast and nipple-areola complex in males compared to females

    Differences between both sexes in localization or representation of the breast in the somatosensory cortex will be assessed.

    Measured: 90 minutes

  2. Changes in the blood oxygen level dependent (BOLD) contrast as a function of vibrotactile stimulation of the breast and nipple-areola complex between individuals of the same sex

    Differences between individuals of the same sex in localization or representation of the breast in the somatosensory cortex will be assessed.

    Measured: 90 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Functional MRI scan in people with Healthy, run by Maastricht University Medical Center at 1 site in Netherlands.

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 5 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 6 Feb 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 Netherlands. 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 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?

Changes in the blood oxygen level dependent (BOLD) contrast as a function of vibrotactile stimulation of the breast and nipple-areola complex (time frame: 90 minutes). 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 6 Feb 2018.
