Can a simple ultrasound spot stroke patients at risk of choking?
NCT ID NCT04874454
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests whether a laryngeal ultrasound can evaluate vocal cord movement in people who recently had a stroke. Researchers will follow 200 participants for one year to see who develops choking or aspiration pneumonia. The goal is to find a non-invasive way to identify high-risk patients early.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ultrasound
- What this could lead to
- If successful, this could help doctors identify stroke patients at higher risk of choking or pneumonia, allowing earlier preventive care.
- What could go wrong
- This is an early observational study with no treatment being tested. The ultrasound method may not reliably predict complications, and results may not apply to all stroke patients.
