Full research ethics approval will be obtained prior to commencement of the study. Participants will be recruited from patients completing esophageal manometry at the South Health Campus. Patients who have provided consent to be contacted for research studies and who have dysphagia and findings of ineffective esophageal motility (IEM) on manometry will be contacted by the study investigators. The results of their esophageal manometry will be reviewed with them, and the study will be described to them. If the patient is interested in study participation, then study investigators will arrange for the patient to come to the South Health Campus to review the study in detail prior to obtaining informed consent. Thirty patients will be enrolled in this study.
