Manometry is performed to assess motor function of the esophagus. A catheter with several electronic pressure probes is passed into the stomach to measure esophageal contractions and to define upper and lower esophageal responses to swallowing. Manometry reveals definitive abnormalities in only 25% of patients with nonobstructive lesions; therefore, its clinical use in oropharyngeal dysphagia is limited.

Manometric fluoroscopy consists of manometry combined with VFSS. It is used to check the pressure gradient of the pharynx and the pharyngoesophageal junction.
