Effects of a Sour Bolus on Oropharyngeal Swallowing Measures in Patients With Neurogenic Dysphagia
Abstract
This study examines the effects of a sour bolus (50% lemon juice, 50% barium liquid) on pharyngeal swallow measures in two groups of patients with neurogenic dysphagia. Group 1 consisted of 19 patients who had suffered at least one stroke. Group 2 consisted of 8 patients with dysphagia related to other neurogenic etiologies. All patients were selected because they exhibited delays in the onset of the oral swallow and delays in triggering the pharyngeal swallow on boluses of 1 ml and 3 ml liquid barium during videofluoroscopy. Results showed significant improvement in oral onset of the swallow in both groups of patients and a significant reduction in pharyngeal swallow delay in Group 1 patients and in frequency of aspiration in Group 2 patients with the sour as compared to the non-sour boluses. Other selected swallow measures in both subject groups also improved with the sour bolus. Volume effects were present but not as consistently as in prior studies. Implications for swallow therapy are discussed.

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.
