title: Dynamic position testing for the detection of esophageal acid reflux disease.
abstract: Currently the most widely accepted study for the detection of significant esophageal reflux disease is the 24-hr pH study. It is a problematic study, however. The data obtained from that study have to be analyzed by comparison to a normal tested population, revalued through a weighted scale, then judged against recorded symptoms in order to obtain a valid interpretation. Dynamic position acid reflux testing has recently been described as a better alternative. In this comparative study between dynamic position and 24-hr pH testing in 64 patients, the dynamic position study was found to be more definitive, more informative, and more efficient in the detection of significant esophageal acid reflux disease.
