Esophageal motility study - An EMS is typically done to evaluate suspected disorders of motility or peristalsis of the esophagus. These include achalasia, diffuse esophageal spasm, nutcracker esophagus and hypertensive lower esophageal sphincter. These disorders typically present with dysphagia, or difficulty swallowing, usually to both solids and liquids even initially. Other patients with spasm disorders may have the test done to diagnose chest pain thought not to be of cardiac cause.

Nutcracker esophagus

Nutcracker esophagus

The esophagus is a muscular tube that contracts in a wavelike manner during swallowing to help move the food and liquid you eat and drink to your stomach. Sometimes, the esophagus spasms and contracts, which can lead to choking. The cause of esophageal spasms is not known, but extremely hot or cold foods sometimes trigger the spasms in some people.
