Outcome Measures

Primary Outcomes (1)

  • Reduction in Reflux Symptom Index Score (RSI)

    Does intervention reduce RSI score from before intervention to follow up.

    3 months.

Secondary Outcomes (2)

  • Association of RSI to resting manometry pressure in the lower esophagus

    1 day

  • Can lower esophageal pressure can be increased by instruction/coaching by a physical therapist.

    1 day

Study Arms (1)

Esophageal Manometry

Esophageal manometry is a test to assess motor function of the upper esophageal sphincter, esophageal body and lower esophageal sphincter

Procedure: Esophageal Manometry

Interventions

A catheter inserted through the nares, post appropriate anesthetization. The subject is then given 8 - 10 sips of water or semi viscous fluid during the routine study. At the conclusion of the clinical portion of the examination the manometer catheter is typically removed by the technician at that point. For the purposes of this research study the catheter will remain in place to examine pressures specifically at the lower end of the esophagus during various breathing patterns and training activities to see if pressures can be increased with instruction.
