This study investigated the effects of six consistencies on measures of swallow duration, muscle activity, and sound. Electromyographic (EMG) recordings of the submental and infrahyoid muscle complexes, and audio recordings of neck sounds were made while 5 normal subjects swallowed two foods in each of three consistency categories: liquid, thin paste, and(More)
BACKGROUND The relationship between subjective complaints of dysphagia and objective measures of swallow function in patients with cancers of the oral cavity, pharynx, or larynx, treated with radiotherapy +/- chemotherapy has not been well documented in the literature. METHODS Swallowing function in 132 patients with various lesions was evaluated using(More)
BACKGROUND Current research demonstrates that swallow function is impaired after treatment with organ-sparing chemoradiotherapy. Few studies, however, have related observed swallowing disorders with the patient's oral intake and diet in a large cohort of patients. METHODS Swallowing function was examined using the modified barium swallow (MBS) procedure(More)
This study was designed to investigate the ability of normal young adult volunteers to sensorially identify Newtonian fluids of specified viscosities. Twenty subjects, 10 men and 10 women between the ages of 18 and 29 years participated. Seven stimuli, consisting of combinations of corn syrup and water, with viscosities ranging from 2 to 2,240 centipoise(More)
BACKGROUND Treatment for head and neck cancer can reduce peripheral sensory input and impair oropharyngeal swallow. This study examined the effect of enhanced bolus flavor on liquid swallows in these patients. METHODS Fifty-one patients treated for head and neck cancer with chemoradiation or surgery and 64 healthy adult control subjects served as(More)
BACKGROUND Intensity-modulated radiotherapy (IMRT) is hoped to protect structures important for swallow function. We compared posttreatment swallow function in 7 pairs of patients with head and neck cancer treated with either IMRT or conventional radiotherapy (RT). METHODS Patients were matched on tumor characteristics. Swallowing function was evaluated(More)
BACKGROUND Postoperative swallowing function may be influenced by a number of treatment variables; this study examines the relationship of various treatment factors to measures of swallow function. METHODS Swallowing was examined with the modified barium swallow procedure in 144 patients surgically treated for oral or oropharyngeal cancer 3 months after(More)
Fourteen participants (six females, eight males) ranging in age from 7 years 11 months to 18 years 2 months (mean 11y 7mo) with a confirmed diagnosis of spastic cerebral palsy (CP) were included in the study. Participants included those who drooled (CP+, n=14); age- and sex-matched children with spastic CP who were dry to mild and never to infrequent(More)
Pharyngeal manometry complements the modified barium swallow with videofluoroscopy (VFS) in diagnosing pressure-related causes of dysphagia. When manometric analysis is not feasible, it would be ideal if pressure information about the swallow could be inferred accurately from the VFS evaluation. Swallowing function was examined using VFS and concurrent(More)
