Sound waves aim to ease stuttering in early trial
NCT ID NCT07668882
First seen Jun 26, 2026 · Last updated Aug 13, 2026 · Updated 4 times
Summary
This study tests whether low-intensity focused ultrasound (LIFU), a gentle sound wave technique, can safely improve speech fluency in people who stutter. Twenty adults who stutter will receive LIFU or a sham treatment, and researchers will measure changes in stuttering severity and brain activity. It is an early safety trial, not a proven treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- low-intensity focused ultrasound (LIFU) device
- What this could lead to
- If it works, this could point toward a noninvasive, drug-free way to temporarily reduce stuttering.
- What could go wrong
- This is a very early, small safety study with only 20 people. It may not show clear benefits, and any effects might be short-lived.
