Trial summary

The purpose of this research study is to determine whether brain anatomy impacts the efficacy of transcranial magnetic stimulation (TMS) which is a form of non-invasive brain stimulation. TMS is used to stimulate different areas of the brain and it is well tolerated and generally a safe procedure. Read more about this study

About this study

The purpose of this research study is to determine whether brain anatomy impacts the efficacy of transcranial magnetic stimulation (TMS) which is a form of non-invasive brain stimulation. TMS is used to stimulate different areas of the brain and it is well tolerated and generally a safe procedure. It has been studied by researchers for 20 plus years. This brain stimulation device and technique used in this study is an investigational device that has not been approved by the U.S. FDA for treating any muscle or nerve problems.

Being tested

What is being measured

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

  1. Change in Corticomotor Excitability With Active Stimulation on Bicep Muscle

    The amplitude the motor evoked potentials (MEPS) will be used to determine level of corticomotor excitability

    Measured: approximately 7 days

  2. Change in Corticomotor Excitability With Sham Stimulation on Bicep Muscle

    The amplitude the motor evoked potentials (MEPS) will be used to determine level of corticomotor excitability

    Measured: approximately 7 days

  3. Change in Corticomotor Excitability With Active Stimulation on Finger Muscle

    The amplitude the motor evoked potentials (MEPS) will be used to determine level of corticomotor excitability

    Measured: approximately 7 days

  4. Change in Corticomotor Excitability With Sham Stimulation on Finger Muscle

    The amplitude the motor evoked potentials (MEPS) will be used to determine level of corticomotor excitability

    Measured: approximately 7 days

Questions about this trial

What is this clinical trial studying?

A study of Healthy, run by Virginia Commonwealth University at 1 site in United States.

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 2 inclusion and 4 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 May 2024. 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 United States. 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?

Yes. Results are posted in the registry (first posted 18 Dec 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Corticomotor Excitability With Active Stimulation on Bicep Muscle (time frame: approximately 7 days). The study lists 4 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 May 2024.
