This study investigates inter- and intrajudge reliability of a clinical examination of swallowing in adults. Several investigations have sought correlations between clinical indicators of dysphagia and the actual presence of dysphagia as determined by videofluoroscopy. Whereas some investigations have reported interjudge reliability for the videofluoroscopic measures employed, none have reported reliability...
Abstract. In order to advance our understanding of the relation between respiration and deglutition, simultaneous videofluoroscopy and respirodeglutometry was performed. Fifteen normal, healthy, young adults (2029 years of age) were connected to a respirodeglutometer and positioned for simultaneous videofluoroscopic assessment in the lateral plane. Subjects performed three swallows each of a 5-ml...
Abstract. This study was designed to determine whether significant differences in SpO2 levels existed among elderly individuals with dysphagia, and, more specifically, whether pulse oximetry can discriminate dysphagic from nondysphagic individuals. In addition, differences in SpO2 between liquid aspirators, solid aspirators, laryngeal penetrators, and normals was investigated in a sample of 181 subjects,...
This is a retrospective study of 378 consecutive stroke patients who were referred between June 1994 and June 1997 for videofluorographic study of oropharyngeal swallow. Patients who had radiation therapy, brain tumor, brain surgery, head and/or spinal cord trauma, oral–pharyngeal disease or surgery, or other neurologic diseases in addition to the stroke were excluded from the study. Patients were...
Abstract. This article describes the results of a study that investigated how well wet phonation can predict penetration and/or aspiration of ingested material in dysphagic patients. Voice samples of 23 subjects with neurologic oropharyngeal dysphagia were collected immediately after each subject had swallowed nine different boluses on videofluoroscopy. The boluses were graded according to three different...
Dynamic videofluoroscopic swallow studies were performed on 60 normal adult volunteers to establish normative data for clinically useful timing measures. The relation of swallowing gesture timing to the timing of actual bolus transit was of particular interest because it provides insight into the physiology of larger bolus volume accommodation. Parameters evaluated include the timing of bolus pharyngeal...

Abstract. The purpose of this investigation was to evaluate the immediate and clinically relevant information gained from the modified barium swallow study and to determine the impact of the procedure on patient management. A database containing a nonrandom sample of 608 swallowing studies was reviewed. Results showed that only 10.4% of the studies were classified as normal examinations and aspiration...
The purpose of this review is to evaluate the disorder of swallowing apraxia and determine how it fits into the praxis system. Swallowing apraxia, a proposed disorder of lingual, labial, and mandibular coordination, has been observed before bolus transfer during the oral stage of swallowing. Although frequently discussed anecdotally in dysphagia literature, the possible mechanisms and neural networks...
Dynamic videofluoroscopic swallow studies were performed on 60 normal adult volunteers to establish normative data for displacement of upper aerodigestive tract structures during deglutition. Variables evaluated included hyoid bone displacement, larynx-to-hyoid bone approximation, pharyngeal constriction, and the extent of pharyngoesophageal sphincter (PES) opening during liquid swallows of 1, 3,...
