Brief Summary

Introduction Patients with stroke 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, the investigators may avoid aspiration and can instruct patients on preventative or compensatory swallowing techniques. Materials and methods

1. 1.Oral 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.
2. 2.Ultrasound 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 epiglottis movements during swallowing.
3. 3.Modified 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 at the same time epiglottis movement will be trace with ultrasound. The barium is given in three consistencies-thin, medium and thick (pudding-like).

Study Population

The Stroke Center inpatients and outpatients with known or suspected dysphagia can be included for study as well as patients who are admitted specifically for this protocol. (Difficulty swallowing food or pills,changed swallowing ability,coughing or choking when eating, shortness of breath during swallowing, food backing up into the mouth or nasal passage, fever or voice changes after swallowing, pain when swallowing, unexplained loss of weight.

You may not qualify if:

• Patients who are severely demented or severely compromised will be excluded if they do not have sufficient cognitive ability to follow directions. Non-ambulatory patients will be excluded if they cannot be braced or supported within the fluoroscopy unit. Highly agitated individuals will also be excluded if they are unable to remain confined in the equipment.
