Measurement of Upper Aerodigestive Tract Pressures During Phonation
This study is testing whether a tool called High-Resolution Manometry can help diagnose a voice condition called laryngeal dystonia (also known as spasmodic dysphonia) and track how well treatment is working. High-Resolution Manometry is a test that measures pressure in your throat using a small, flexible tube. The procedure is brief and designed to be as comfortable as possible. Researchers think that people with laryngeal dystonia may have different pressure patterns in their throat compared to people without the condition or with other voice problems. If this tool can help identify laryngeal dystonia earlier, it may allow patients to get the right treatment sooner.
