About this study

Official title: Stroke Therapy With Brain Oscillation Synchronized Stimulation: Randomized Controlled Pilot Study to Compare the Therapeutic Effectiveness of a Personalized EEG-triggered Repetitive High-frequency TMS Therapy Protocol With Standard Low-frequency TMS Therapy Protocol in Patients With Spastic Paresis

This randomized, controlled, double-blind clinical pilot trial investigates the therapeutic potential of a novel personalized therapeutic brain-stimulation protocol in chronic stroke patients with spasticity. Stroke patients will either receive ipsilesional 100 Hz transcranial magnetic stimulation (TMS) triplet burst protocol synchronized to the ongoing µ-alpha oscillation or contralesional 1 Hz repetitive TMS (rTMS) protocol. Motor recovery is assessed directly after as well as three months after completion of the therapy.

Read the detailed description

Stroke is one of the leading cause for long-term disability worldwide. The standard approach to treat deficits after stroke is a rehabilitation therapy, that follows the stroke event directly. This therapy mainly includes physiotherapy and occupational therapy. Yet, despite intensive rehabilitation efforts, more than half of all stroke patients remain greatly disabled.

Repetitive TMS is capable of inducing plasticity-like effects in the brain, that are expected to enhance adaptive plasticity processes leading to functional regain after stroke. In the motor cortex, brain oscillation-synchronized TMS, i.e. TMS triggered dependent on the phase of instantaneous µ-alpha oscillations as detected by real-time EEG (electroencephalography) analysis, has been shown to consistently increase motor cortical excitability and plasticity effects. We therefore hypothesis that a greater therapeutic potential of TMS to modulate dysfunctional brain networks can be exploited by personalizing TMS therapy to individual brain states (i.e. brain oscillations).

This study aims to investigate the effectiveness of an ipsilesional 100 Hz TMS triplet burst protocol synchronized to the ongoing µ-alpha oscillation compared to the current TMS standard therapy of contralesional 1 Hz rTMS in chronic stroke patients. Both groups will undergo stimulation therapy three times a week, with each session directly followed by physiotherapy. Motor recovery will be assessed directly after as well as three months after completion of the therapy.

Questions about this trial

What is this clinical trial studying?

A study testing Negative peak triggered 100 Hz triplet burst TMS and 1 Hz rTMS in people with Stroke, run by University Hospital Tuebingen at 1 site in Germany.

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 12 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 18 Aug 2023. 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 Germany. 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?

Change in Fugl-Meyer Assessment Upper Extremity (FMA-UE) (time frame: Difference of score directly before intervention and score directly after intervention). 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?

On the ClinicalTrials.gov record for NCT05005780, which also lists 1 linked publication.

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 18 Aug 2023.
