Trial summary

Recent studies have identified new neurobiological biomarker (i.e. functional connectivity of the parietal cortex) of motor learning among healthy people. This enables to refine our current model of motor learning wherein specific cortical processes are key factors for motor acquisition. Read more about this study

About this study

Official title: Effects of rTMS on Brain Plasticity and Motor Learning in Healthy People.

Recent studies have identified new neurobiological biomarker (i.e. functional connectivity of the parietal cortex) of motor learning among healthy people. This enables to refine our current model of motor learning wherein specific cortical processes are key factors for motor acquisition. Furthermore, recent evidence suggests that new technical approaches such as repetitive magnetic stimulation (rTMS) can efficiently influence this key factor. However, up to now, no rTMS studies have target this new biomarker. Therefore, the effect of rTMS are unknown. Hence, the investigators want to develop a new rTMS setup able to induce specific brain processes in healthy individuals that are likely to benefit. This has the potential to obtain critical information in order to improve treatment of motor re-learning in patients with neurological diseases.

Read the detailed description

Participants will participate in 1 session of neuronavigated (TMS Navigator, Localite, Schloss Birlinghoven, D-53757, Sankt Augustin, Germany ) iTBS (patterned form of rTMS) coupled with motor learning. Participants will be randomly assigned to one of 2 groups: real iTBS over parietal cortex and sham iTBS over the parietal cortex.

One day before (Day1) and after the motor learning (Day 2), participants will undergo high-density 128-channel resting state electroencephalography (EEG) and motor evoked potential (MEP) in order to characterize the effects of rTMS on our markers of plasticity. Performance on the task will be measure immediately after learning (Day 2) and again 24h later (Day 3) in order to test for retention and offline consolidation (time and errors). The task will consist in realizing a computerized mirror-drawing task, in which right-left movements of the mouse were reversed on the screen.

  • rTMS deviceDevice

    Participants will participate in 1 session of neuronavigated (TMS Navigator, Localite, Schloss Birlinghoven, D-53757, Sankt Augustin, Germany ) iTBS (patterned form of TMS) coupled with motor learning.

Study groups in NCT04140994
Study groupRoleWhat they receive
Intermittent theta burst stimulationActive comparatorVolunteers will be submitted to non-invasive parietal stimulation before a mirror drawing task. A transcranial magnetic stimulator (MagPro X100, Medtronic Functional Diagnostics, Skovlunde, Denmark) will deliver interrmittent bursts of bipolar magnetic pulses exerting an excitation on the underlying brain tissue (iTBS). The stimulation coil will be placed over the parietal cortex. Stimulation consisted of a burst of three pulses administered at 50Hz, repeated at a frequency of 5Hz, delivered in 2 s trains followed by an 8 s interval for a total of 600 pulses12. Stimulation intensity was set at 70% of RMT. Each session will consist of two spaced neuronavigated iTBS applications, separated by 15 minutes.

What is being measured

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

  1. Motor performance in consolidation test

    Difference in error rate and speed improvement in active and sham groups (learned task)

    Measured: after training (Day 3)

Secondary outcomes (2)
  1. Resting state EEG connectivity in active and sham groups

    Calculated from electroencephalography recordings

    Measured: Before (Day 1) and after training (Day 2)

  2. Motor Evoked Potential (MEPs) Amplitudes (peak to peak)

    Difference in MEPs between active and sham groups. MEPs are generated when stimulation of the brain on the motor cortex (with Transcranial Magnetic Stimulation [TMS]) causes the spinal cord and peripheral muscles to produce neuroelectrical signals. MEPs are typically measured in the hand muscles (Abductor pollicis brevis ).

    Measured: Before (Day 1) and after training (Day 2)

Questions about this trial

What is this clinical trial studying?

A study testing rTMS device in people with Healthy, run by University of Geneva, Switzerland at 1 site in Switzerland.

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 6 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: status not confirmed, as of the sponsor's last update on 29 Oct 2019. 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 Switzerland. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Pierre Nicolo, PhD (+41 (0)22 372 38 76, pierre.nicolo@hcuge.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Motor performance in consolidation test (time frame: after training (Day 3)). 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 29 Oct 2019.
