NCT ID NCT05497219
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is creating a set of reference values for videofluoroscopic swallowing tests, which are X-ray videos of people swallowing different liquids. Researchers will compare healthy adults of all ages to people with swallowing difficulties (dysphagia) from conditions like stroke or aging. The goal is to help doctors more accurately diagnose when swallowing is unsafe or inefficient.
