Abstract. In this investigation, surface electromyographic (EMG) recordings were used to make qualitative and quantitative analyses of labial muscle activity during three swallowing tasks, incorporating the use of various drinking implements. EMG was recorded from four quadrants of the perioral region and from the submental muscle complex in 11 normal adult females. Swallowing tasks included liquid...
Abstract. Twenty-three speech-language pathologists (SLPs) experienced with thickening liquids for dysphagia evaluations were asked to mix solutions comparable to their perceptions of nectar, honey, and pudding consistencies. The purpose of the study was to determine if these professionals were able to reliably repeat their relative perceptions of nectar, honey, and pudding over multiple mixings....
. Dysphagia, a difficulty eating or drinking, appears to increase with age and is a concern for our growing elderly population. Mastication, tongue mobility, and lip closure are skills of the oral phase of ingestion, and have been shown to deteriorate with age. However, it is not clear whether these changes affect functional feeding. It is also unclear whether dysphagia is the result of the aging...
Abstract. The purpose of this study was to investigate the incidence of aspiration following extubation in critically ill trauma patients. This prospective pilot study included 20 consecutive trauma patients who required orotracheal intubation for at least 48 hours. All subjects underwent a bedside transnasal fiberoptic endoscopic evaluation of swallowing at 24 2 hr after extubation to determine objectively...
. The nutcracker esophagus, a primary motor disorder, is frequently associated with noncardiac chest pain. However, there are no data on whether its diagnosis, as in other esophageal motility disorders, is delayed. Since the disorder is frequently heralded by alarming symptoms such as chest pain and dysphagia, diagnosis should be made as soon as possible. In this study we assessed the diagnostic...

Abstract. Videofluoroscopic assessment of swallowing is widely used in clinical settings. The interpretation of such assessments depends on subjective visual judgments but the reliability of these judgments has been poorly researched. This study measured interrater reliability of judgments, made by speech pathologists, of videofluoroscopic images of subjects swallowing liquid and semisolid boluses...

This prospective pilot study included 20 consecutive trauma patients who required orotracheal intubation for at least 48 hours. All subjects underwent a bedside transnasal fiberoptic endoscopic evaluation of swallowing at 24 ± 2 hr after extubation to determine objectively...
Abstract. The purpose of this study was to retrospectively evaluate the radiologic findings in young adults with dysphagia undergoing barium swallow and to compare these with the final clinical diagnosis. Clinical history, barium swallow, endoscopy (21 patients), manometry (18 patients), 24 h pH monitoring (4 patients), and outcome of treatments were studied and compared in 43 patients aged 1430 years...

Abstract. The present study was designed to examine the sensitivity and specificity of a 28-item screening test in identifying patients who aspirate, have an oral stage disorder, a pharyngeal delay, or a pharyngeal stage disorder. The screening test includes 28 items divided into 5 categories: (1) 4 medical history variables; (2) 6 behavioral variables; (3) 2 gross motor variables; (4) 9 observations...
Abstract. We studied 10 normal subjects to determine the effect of doses of intravenous glucagon used to treat food impaction on esophageal motor function. With a multilumen assembly perfused by a low compliance pneumohydraulic infusion pump, esophageal manometry was performed during baseline and after randomized administration of 0.25, 0.5, and 1 mg intravenous glucagon. Mean proximal and distal...
