Brief summary
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.
Detailed description
The esophageal manometry will be performed in the motility lab at the Shands Endoscopy Center by passing a small tube into the patients nose, down the food pipe and into the stomach. The participants will be instructed to swallow a determined volume of Gatorade,depending on the protocol being followed. All participants will be starting in the supine position followed by semi-recumbent,sitting, then standing up. When the esophageal manometry is finished, the tube is removed and participation in this study is complete.
Interventions
PROCEDUREesophageal manometry
Esophageal manometry will be performed by swallowing different amounts of Gatorade depending on the protocol being followed.There will be alternate assignment of positions: supine position, semi-recumbent position,sitting position and standing up position.
DIETARY_SUPPLEMENTGatorade
The patient will be given Gatorade to drink at various times during the study.
OTHERSupine position
Esophageal manometry will be performed by swallowing different amounts of Gatorade depending on the protocol being followed. There will be alternate assignment of positions: supine position, semi-recumbent position,sitting position and standing up position.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Normal values for HRM while the patient is in the most physiologic position to stimulate normal eating habits. | up to 1 hour | The patient is instructed to swallow a determined volume of Gatorade. All participants will be starting in the supine position followed by semi-recumbent,sitting, then standing up. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Normal HRM values for a 200 ml provocative swallow. | up to 5 minutes | The patient is instructed to swallow 200 ml of Gatorade in the sitting position. |
| Bolus clearance for each swallow with impedance. | up to 1 hour | The patient is instructed to swallow a determined volume of Gatorade. All participants will be starting in the supine position followed by semi-recumbent,sitting, then standing up. |
| Normal size and diameter of esophagus and esophageal distension on a regular basis with the provocative swallow and impedance. | up to 1 hour | The patient is instructed to swallow different amounts of Gatorade. All participants will be starting in the supine position followed by semi-recumbent,sitting, then standing up. |
| Standardization of the testing protocol for HRM and the reliability of volume and number of swallows. | up to 1 hour | The patient is instructed to swallow different amounts of Gatorade. All participants will be starting in the supine position followed by semi-recumbent,sitting, then standing up. |
