Inclusion Criteria: - Normal Volunteers: - Older than 55 years of age - No history of voice, swallowing, reflux, or progressive neurologic disease affecting the swallowing mechanism. - A normal self-administered dysphagia questionnaire (EAT-10 score of less than three) - Patients with Dysphagia - Older than 55 years of age - Patients with the following condition: Dysphagia, globus, gastroesophageal reflux, or any other condition requiring referral for a dynamic swallowing study. - Patients willing to provide written informed consent for their participation in the study. Exclusion Criteria: 1. Patients unable to complete the administration of the full taste and viscosity protocol. 2. Patients with profound dysphagia unable to safely consume the test solutions. 3. Patients with known sensitivities or allergies to any of the test solutions. 4. Patients who are prisoners. 5. Patients have a history of diabetes. 6. Patients who are unable to follow the simple instructions to swallow the test solutions on instruction and answer the questionnaire. |

---|---|---|---|---|
Primary | Swallowing amplitude as measured on digital accelerometry. | Digital accelerometry is a non-invasive method of measuring swallowing efficiency. A surface sensor is taped to the skin over the region of the thyroid prominence. When the patient swallows, the sensors measures upward acceleration of the thyroid cartilage and a measurement of swallowing amplitude, a surrogate measure for swallowing efficiency, is obtained. | Measurement is made at the time of patient participation. | |
Secondary | To evaluate swallowing efficiency. | Peak pharyngeal pressure, upper esophageal sphincter (UES) residual pressure, and UES relaxation time, all surrogate measure sof swallowing efficiency, will be measured using pharyngeal manometry. | Measurement is taken at the time of patient participation. |
