 About the contributor

The aim of the "How To..." section is to provide guidance on how to perform a range of procedures used for evaluation of patients with motility-related upper GI tract disorders. Each procedure is demonstrated by a video.

These "How To..." presentations are intended to cover only the basic principles of the techniques involved; safe and effective performance must be learned with guidance from a skilled practitioner.

For completeness, this section concludes with "How to Set Up and Manage a Motility Laboratory."

Video 1 demonstrates the technique of three-site pharyngeal pH monitoring. Owing to inherent difficulties of pH recording from the pharyngeal cavity, this procedure is not as commonly used as esophageal pH recording.
