TS-005520 — This new testing process, with both clinical and research applications, has been developed to characterize biomarkers of swallowing rhythms, patterns, and oral feeding abilities in the evaluation of GERD (gastro-esophageal reflux disease). This method of testing expands upon pH-Impedance testing (pH-IMP), the standard for evaluating GERD, utility without adding additional strain on patients at the point-of-care by developing characterization of swallowing patterns using software during feeding sessions and lead to new therapies to be examined.
