NCT ID NCT06735794

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at how two different ways of giving a type of non-invasive brain stimulation called iTBS affect brain plasticity—the brain's ability to change and adapt. 29 healthy, right-handed adults aged 18 to 50 took part. Researchers compared a standard stimulation pattern with a spaced-out version and a fake (sham) stimulation to see which one caused the most change in brain activity.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

29 people

The number who actually took part.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 50 years

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age 18 years or above, and less than 51 years. 2. Right handedness, assessed using the Edinburgh Handedness Inventory (EHI). 3. Sufficiently proficient in English to complete the required study assessments, as per investigator judgement. 4. Willingness and capacity to provide informed consent. 5. Willingness to comply with all study procedures. Exclusion Criteria: 1. Age 17 years or less, or greater than 51 years, as brain plasticity is known to be affected by age. 2. Current use of any psychotropic medications (e.g. anti-depressants, anti-convulsants, anti-psychotics, etc.). 3. Contraindications to transcranial magnetic stimulation (TMS), as per investigator judgment. 4. Lifetime history of any Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnosis, assessed using the Structured Clinical Interview for DSM-5 (SCID-5), except simple phobias. 5. Left handed or ambidextrous, assessed using the EHI, to minimize the heterogeneity in cortical excitability and plasticity. 6. Self-reported history of seizures and/or other major neurological conditions, as per investigator judgement, due to the risk of seizures associated with TMS in individuals with a heightened risk.
