Manometric Abnormality in Dysphagic Patients after Medullary Cerebrovascular Accidents
Abstract
We investigated the pharyngeal swallowing function using videomanofluorometry (VMF) in patients after medullary cerebrovascular accidents. Upper esophageal sphincter pressure, which should drop when a bolus arrives at the hypopharynx, increased at the same time as the elevation of oropharyngeal and hypopharyngeal pressures. A reduction of oropharyngeal and hypopharyngeal swallowing pressures was also observed. Our results suggest that a misprogrammed excitatory output from the central pattern generators of the brain stem would cause an abnormal pressure-traveling pattern of pharyngeal swallowing. VMF was useful to assess the pharyngeal swallowing function and to determine the indications for cricopharyngeal myotomy for patients after medullary cerebrovascular accidents.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
