Abstract

Background Swallow function is best analyzed in components because discrete component failure may be compensated for with devised maneuvers, postures, or biofeedback techniques. The present investigation examined normal deglutitive tongue function.Methods Biplane videofluoroscopy synchronized with intraluminal manometry was performed in eight volunteers. Tongue surface motion was characterized as centripetal or centrifugal along seven equiangular rays emanating from the tongue center during 1-, 5-, 10-, and 20-mL swallows.Results The tongue perimeter remained in contact with the alveolar ridge while the central groove exhibited centripetal and subsequent centrifugal motion that, in conjunction with the pharyngeal walls, created an oropharyngeal propulsive chamber and then expelled that chamber's contents into the hypopharynx. Intrabolus propulsive pressure was generated when the initially expansive propulsive chamber volume contracted to the test bolus volume. Because pharyngeal chamber action cycle timing was relatively constant among bolus volumes, vigorous expulsion occurred with large volumes but relatively delayed, sluggish expulsion occurred with smaller volumes.Conclusions Deglutitive tongue functions include bolus containment, volume accommodation, and the major contributor to bolus propulsion.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Early work by Logemann and colleagues demonstrated contributions of oral tongue movement to onset of pharyngeal swallowing dynamics.

    “This finding fits with the early work of Logemann and colleagues who demonstrated the contributions of oral tongue movement to the onset of pharyngeal swallowing dynamics [66–69].”

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.
