Participants will undergo the following procedures:\n\nOral examination-A neurologist and speech pathologist examine the patient's swallowing function. The patient is interviewed about difficulties with food intake, chewing and swallowing during meals.\nUltrasound examination-Ultrasound creates image of areas inside the body using sound waves. With the patient in a sitting position, a 3/4-inch transducer (device for transmitting and receiving sound waves) is placed under the chin to visualize tongue movements during swallowing.\nModified barium swallow-While standing or sitting, the patient swallows 1/2 teaspoon of flavored barium (a radioactive substance) six times (a total of 3 teaspoons), while the tongue and pharynx (tube leading from the mouth to the esophagus) are scanned and videotaped. The barium is given in three consistencies-thin, medium and thick (pudding-like).\nElectromyography-A small plastic strip with wires attached is placed under the patient's chin. The patient then swallows 1/2 ounce of barium three times in a row, and the movement of the chin muscles during swallowing is displayed. Patients may also be asked to swallow 5/8 cup of barium twice; once with the head tilted upward and once with the head untilted.\n\nDepending on the test results, patients may be asked to return for follow-up study and monitoring.", "DetailedDescription"=>"Patients with neurological or neuromuscular conditions may be silent aspirators or at risk for laryngeal penetration or aspiration because of abnormal oropharyngeal functioning and thus are at risk for aspiration pneumonia and its serious effects. By providing identification of the components of the abnormal swallow, and comparing swallowing across tasks, we may avoid aspiration and can instruct patients on preventative or compensatory swallowing techniques.\n\nWe will study the oral, pharyngeal and upper esophageal phases of swallow using both ultrasonic imaging and videofluoroscopy in patients with neurologic, genetic, systemic, and neuromuscular conditions. Most of the previous studies of swallowing have utilized only one diagnostic imaging technique and have thus provided an incomplete swallowing assessment as each procedure has unique, but limited capabilities for visualizing the anatomy and physiology of the swallow.\n\nWe also plan to compare discrete and continuous swallowing in these populations. While the motor physiology for discrete swallowing (i.e., single swallow) has been well studied, little is known about the details of oral, laryngeal, and pharyngeal coordination during sequential swallowing as a part of continuous drinking--a common event in everyday eating. A portion of the protocol will study the effects of fast-paced movement sequencing on the coordination of the tongue, velum, larynx, and pharynx during continuous drinking. Videofluoroscopy and ultrasound may be paired or used individually to collect data from normal subjects and patients with known dysphagia while they perform sequential and discrete swallowing tasks. A number of timing and displacement measurements of the structures activated during these tasks will be made from the digitized video images of each swallow, and analyses will be carried out subsequently across tasks and subjects."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"INCLUSION CRITERIA:\n\nAny Clinical Center inpatients and outpatients with known or suspected dysphagia on any other NIH institute protocol can be included for study as well as patients who are admitted specifically for this protocol.\n\nThose patients at risk for oropharyngeal dysfunction will be screened initially by completing a self-assessment swallowing questionnaire, and by an interview with staff and/or family members.
