title: Esophageal motility disorders and chest pain.
abstract: Motility abnormalities have long been recognized as a possible esophageal cause of chest pain; however, their exact role and prevalence remain largely unknown. Baseline manometry and the various provocative tests may suggest an esophageal origin, but their yield is low. The recent advent of prolonged ambulatory monitoring of intraesophageal pressure and the assessment of psychological factors are contributing to a clearer understanding of this complex problem.
