简要总结
This study is designed to determine the impact of a pharyngeal High Resolution Manometry catheter on swallowing biomechanics
详细描述
During pharyngeal High Resolution Manometry (pHRM) a small bore flexible catheter is introduced into the pharynx to detect intrabolus pressure and contact of pharyngeal structures during swallowing. The presence of the catheter through the upper esophageal sphincter (UES) leads to a violation of its natural closed state. It is not clear how this intrusion influences the swallowing biomechanics . Hence, this project's goal is to identify how hyoid movement is altered during swallowing with the presence of a pHRM catheter in place.

研究组 & 干预措施
Randomization Visit A
Participants enrolled in this arm will consume 300ml of water over 60 minutes. Each session will consist of 30 swallows broken into three 10-swallow sequences of 10ml of water. Each sequence will be use VFSS to visualize swallows.
干预措施: Videofluoroscopic swallow study (Procedure)
Randomization Visit B
Participants enrolled in this arm will consume 300ml of water over 60 minutes. Each session will consist of 30 swallows broken into three 10-swallow sequences of 10ml of water. Sequences 1 and 3 will use videofluoroscopy only, while sequence 2 will use VFSS with simultaneous pharyngeal high resolution manometry in order to visualize swallows.
