Shocking the brain back to speech: new hope for stroke survivors
NCT ID NCT03651700
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether combining transcranial magnetic stimulation (TMS) with language therapy helps people with chronic aphasia—a language disorder after stroke—speak better. 86 participants received either real TMS or a sham version, plus language therapy, over two weeks. The main goal was to see if language scores improved six months later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Transcranial magnetic stimulation (TMS) and constraint-induced language therapy (CILT)
- What this could lead to
- If it works, this could point toward a non-invasive treatment to improve language recovery in people with long-term aphasia after stroke.
- What could go wrong
- This is a phase 2 trial with only 86 participants, so results may not apply to everyone. The treatment is short-term and effects may fade over time.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Clinical evidence and MRI or CT verification of a single left hemisphere stroke with moderate to severe aphasia. * Suffered their stroke at least 6 months prior to their testing * Must be able to understand the nature of the study, and give informed consent Exclusion Criteria: * Multiple strokes (excluding small lacunar strokes) as defined by brain imaging * History of substance abuse * Previous head trauma with loss of consciousness for more than 5 minutes * Psychiatric illness (We note that subjects will be assessed with the 15-item Geriatric Depression scale. Because depression is very difficult to evaluate in aphasic subjects, potential subjects will not be excluded on the basis of the depression score) * Chronic exposure to medications that might be expected to have lasting consequences for the central nervous system (e.g. haloperidol, dopaminergics) * History of or neuropsychological findings suggestive of dementia
