The purpose of this study is to quantify the added benefit of visual biofeedback from High Resolution Pharyngeal Manometry (HRPM) for swallowing rehabilitation. Primary aims including assessing changes in swallowing biomechanics (pressure generation, timing) during swallow maneuvers with and without HRPM visual biofeedback. Secondary aim includes participant attitudes related to visual biofeedback and the experience of HRPM.

Inclusion Criteria:

1. Participants must be independent community dwelling adults.
2. Participants must be between the ages of 18-40 years old.
3. Willingness to consent and participate in the study procedures.
4. No reported dysphagia or difficulty swallowing evidenced by an EAT-10 Score <3.

Exclusion Criteria:

1. Known structural or neurological causes of dysphagia (e.g., stroke, brain injury, or head/neck cancer).
2. Recent or remote history of swallowing therapy; familiarity with swallowing maneuvers from relevant coursework as applicable (i.e., speech language pathology students).

The de-identified participant data from the final research dataset will be shared upon reasonable request immediately following publication, no end date, provided the requesting investigator executes a data use agreement with NYU Langone Health. This instance of data sharing will also require separate IRB review as well as review from NYU Langone's Data Sharing Strategy Board (DSSB). Requests should be directed to: smm16@nyu.edu. The protocol and statistical analysis plan will be posted on Clinicaltrials.gov only as required by federal regulation or supporting awards and agreements.
