Stroke speech therapy: finding the right dose
NCT ID NCT04364854
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested speech entrainment therapy (SET) in 80 people with non-fluent aphasia after a stroke. Participants practiced speaking along with an audio-visual computer program for 3, 4.5, or 6 weeks, or received no therapy. The goal was to find the best duration for lasting improvements in spontaneous speech.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Speech entrainment therapy (SET) - a computer program that helps practice fluent speech in real time
- What this could lead to
- If successful, this could point toward an optimal therapy duration to improve spontaneous speech in people with non-fluent aphasia after stroke.
- What could go wrong
- This is a small, early-phase study (80 participants) comparing different therapy lengths. Results may not apply to all types of aphasia or stroke survivors.

Inclusion Criteria * Aphasia as a result of a left hemisphere ischemic or hemorrhagic stroke (WAB-R Aphasia Quotient \<93.8). * Presence of left hemisphere stroke in clinical imaging (CT/MRI) and NIHSS * Participants must have spoken English as their primary language. * 21-81 years old * Pre-stroke modified Rankin Scale (mRS)= 2 or less * Post-stroke mRS= 4 or less. * At least 6 months post-stroke. * Non-fluent aphasia (WAB-R Comprehension score \>4 and WAB-R Fluency score \<6). * Technological compatibility (to be determined by clinical judgment of SLP) Exclusion Criteria * History of chronic neurological or psychiatric diseases (excluding migraines, depression, or post-stroke epilepsy). Self-reported history of learning disability. * Severe dysarthria (determined via SLP clinical judgment from spontaneous speech tasks on the ASRS 3.0). * Global aphasia. * History of right-hemisphere strokes or brain stem/cerebellar strokes with persistent deficits (as evidenced by MRI/CT and NIHSS). * Uncorrectable hearing as determined by the SLP's clinical judgment. * Uncorrectable vision. * Contraindications to MRI or inability to complete the MRI scanning session. * Women who are pregnant.
