High Resolution Manometry for Swallowing

This study is using a new technology known as high resolution manometry which is used to evaluate patients that have trouble swallowing or have chest pain that is not related to the heart. The investigator wants to learn how the different positions of the body, in a lying position, semi-recumbent, sitting position or standing up, and the amount of liquid affects the outcome of the test. This will help the investigator to determine a standardized protocol for patients with trouble swallowing.
