About this study
Official title: Probing Language Processes Using Transcranial Magnetic Stimulation
This study will examine the effect of TMS on people with stroke and aphasia as well as healthy individuals.
Read the detailed description
To examine the brain's structure and specific language function and interactive relationships, investigators will implement repetitive or rapid TMS protocols in an active (or sham)-controlled, within-subject, randomized studies. Aims will evaluate the effects of short-term changes on each of the semantic or phonological language process of interest in isolation and changes in the interaction between language sub-processes and their interaction with other cognitive domains that directly or indirectly affect language functions. The brain targets for TMS application will be informed by existing evidence on (correlational but not causal) associations between language regions and specific language processes from numerous prior neuroimaging (e.g., functional magnetic resonance imaging or fMRI) and neuropsychological studies. Healthy individuals and/or stroke survivors with aphasia will be recruited to address these aims.

Questions about this trial
What is this clinical trial studying?
A study testing Transcranial Magnetic Stimulation in people with Stroke and Aphasia, run by Medical College of Wisconsin 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 5 inclusion and 18 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: looking for participants now, as of the sponsor's last update on 13 Jul 2026. 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. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Sidney Schoenrock (414-955-7579, sschoenrock@mcw.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Reaction time on language task performance (time frame: Language tasks administered immediately before and/or after TMS administration (same day).). 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 NCT05425615, which also lists 22 linked publications.
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 13 Jul 2026.
