Summary

This study aims to establish what normal swallowing looks like in healthy adults of all ages using video X-rays. Researchers will compare these normal patterns to those of people with swallowing difficulties (dysphagia) to create clear cutoffs for diagnosis. About 580 participants, including healthy volunteers and patients with swallowing problems, will be enrolled. The goal is to improve how doctors identify and treat swallowing disorders.
