Sound waves to reboot the brain after stroke?
NCT ID NCT07784751
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This early-stage trial is testing whether focused sound wave pulses applied to the head—called transcranial pulse stimulation—can help people recover from a recent ischemic stroke. The study includes adults aged 20 to 80 who had a stroke 1 to 6 months ago and still have motor or language difficulties. Participants receive six sessions over two weeks at different energy levels to find the safest dose and see if it improves movement, balance, and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial pulse stimulation (TPS) using the NEUROLITH® system
- What this could lead to
- If it works, this could point toward a new non-invasive way to help people regain motor function and balance after a stroke.
- What could go wrong
- This is an early, small trial focused on safety and dosing, so benefits are uncertain. There are risks such as seizures, bleeding, or worsening neurological symptoms.
