Official title: Impact of External Pharyngeal Exerciser on Pharyngeal Phase of Swallowing

Run by Medical College of Wisconsin · NCT05708911 · Data updated 2026-11-12

This study is testing how a throat exercise device can help both young and older people swallow better by measuring the pressure in their throats during swallowing.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are healthy adults aged 18 and older without any significant medical history affecting swallowing.

Probably not a fit

Patients with neurological disorders, cervical spine issues, or any current esophageal symptoms will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates how a pharyngeal exerciser affects the pressure in the throat during swallowing in healthy young and elderly individuals. Participants will undergo a series of swallowing tests with varying pressures applied by the device to measure the impact on pharyngeal muscle workload. The study involves precise measurements and recordings using high-resolution manometry to capture the swallowing dynamics. Each participant will perform multiple swallow types under different pressure conditions to assess the exerciser's effectiveness.

Why it matters

Potential benefit: If successful, this study could lead to improved therapies for individuals suffering from dysphagia by enhancing swallowing mechanics.

How similar studies have gone: While similar approaches have been explored, this specific application of a pharyngeal exerciser in healthy individuals is relatively novel.
