Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Oropharyngeal dysphagia, or difficulty swallowing, is a devastating condition that affects physiological and psychosocial functioning in 1 in 25 adults. Many dysphagia treatments exist, but our ability to adequately measure treatment outcomes is limited. Pharyngeal high-resolution manometry (pHRM) directly measures swallowing pressures, providing an objective measurement of physiology that characterizes the basic mechanisms of swallowing. pHRM is well-poised to measure outcomes of dysphagia treatments due to its direct, objective, and reproducible measures of swallowing function.

This proposed project will address a central hypotheses that objective swallowing measures (including (pHRM) will reveal treatment-mediated swallowing changes, will align with patient-reported outcome measures, and will be able to predict who will benefit from treatment. The investigators will follow a cohort of participants with oropharyngeal dysphagia as they undergo either pharyngeal strengthening therapy or relief of upper esophageal sphincter outlet obstruction at three time points: baseline, mid-treatment (4-6 weeks) and post-treatment (10-12 weeks). The investigators will compare participants to healthy controls using pHRM, videofluoroscopy, diet assessment, functional reserve tests, and patient-reported outcome measures.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A: Swallow Therapy Oropharyngeal Strengthening

Participants receiving any standard of care swallow therapy with oropharyngeal strengthening as the primary goal

Participants will undergo pHRM, videofluoroscopy (VF), diet assessment, functional reserve tests, and patient--reported outcome questionnaires at 3 standardized time points: baseline, 4 to 6 weeks (mid therapy), and 10 to -12 weeks (post -therapy)

pHRM

Intervention Type PROCEDURE

Pharyngeal high--resolution manometry (pHRM) provides direct and objective measurement of pressure changes in the pharynx that characterize basic mechanisms of swallowing.

VFSS

Intervention Type PROCEDURE

Videofluoroscopic Swallow Study (VFSS) enables real-time visualization of bolus flow during swallow movement.

Group B: Surgical Treatment Esophageal Sphincter

Participants receiving surgical treatment for relief of upper esophageal sphincter outlet obstruction.

Participants will undergo pHRM, videofluoroscopy (VF), diet assessment, functional reserve tests, and patient--reported outcome questionnaires at 3 standardized time points: baseline, 4 to 6 weeks (mid therapy), and 10 to -12 weeks (post therapy)

VFSS

Intervention Type PROCEDURE

Group C: Healthy Controls

Healthy controls (n=50) will also undergo data collection at parallel time points, without completion of a treatment paradigm.
