Active clinical trials for "Deglutition Disorders"

In this online study, investigators will explore the psychosocial burdens of swallowing difficulties in people with Parkinson's Disease. This study is completely virtual, so you can participate from wherever you live in the United States. Participation requires you to complete a one-hour Zoom interview and a brief questionnaire. You will be compensated with a $25 Walmart gift card. To learn more, please use the "send email" feature. Thank you!

The investigators main endpoint was focused on the analysis of the type, rate and the impact of different clinical parameters on the complications of the PEG tube placements performed at the Department of Otorhinolaryngology - Head and Neck Surgery since October 2008. In addition, the investigators aimed to compare the results with a historic cohort patient group (September 2005 - October 2008) sent to the Department of Surgery for PEG tube placement in order to evaluate the results of the changed routine.

Aspiration could induce major respiratory affection. They are often present after stroke. The aim of this study is to facilitate swallowing recuperation in stroke patients using peripheral laryngeal stimulation and to understand its mechanisms using motor evoked potential and cortical evoked potential.

The purpose of this study is to correlate the alimentary consistencies and deglutition disorders in children with cerebral palsy.

This study will examine tongue strength and endurance, how the tongue applies pressure during swallowing, and how the chin muscles react during swallowing in healthy volunteers and in patients with dysphagia (difficulty swallowing). The information from this study may be helpful in developing better treatments for people with swallowing problems. Healthy volunteers who have no history of speech, swallowing or breathing problems and patients who have difficulty swallowing because of a neurologic disorder, musculoskeletal disease or head and neck cancer that caused tongue weakness and dysphagia may be eligible for this study. Such medical conditions may include stroke, Parkinson's disease, multiple sclerosis corticobasal degeneration, progressive supranuclear palsy, Gaucher's disease, leukodystrophy, cerebral palsy, myositis, or mouth, throat or neck cancer. Volunteers who have not participated in a NIH protocol for 1 year will be screened with a brief medical history and physical examination. Dysphagic patients not currently enrolled in a NIH protocol will also have a brief medical history and physical examination. In addition, they will have a modified barium swallow to determine the nature and degree of their swallowing difficulty. Participants will have a 15-minute examination of movements of their tongue, lips and jaw and will fill out a questionnaire about their swallowing ability. They will then begin the tongue pressure test. To monitor and record tongue pressure, a thin rubber strip with air-filled pressure bulbs will be attached to the roof of the mouth with dental adhesive. The pressure bulbs are connected to an external pressure-reading device. In addition, a small plastic pad with adhesive backing will be placed under the chin. Electrodes (wires) attached to the pad record chin muscle activities. With the pressure bulbs and chin electrodes in place, the patient will perform tongue pressure tasks to test tongue strength, how long the patient can maintain a certain tongue pressure, and how fast tongue pressure drops. The tasks include saliva swallows, water swallows and cup-drinking.

This study will establish a database of fetal movements associated with feeding. It will use information obtained from standard fetal ultrasound procedures to identify and measure the growth of the baby's face, lips, tongue, jaw, throat and airway. Fetal movements involved in breathing, sucking and swallowing will be recorded on videotape. This study may provide information that will: increase knowledge about how swallowing develops in the fetus; help explain why some babies have difficulty sucking and swallowing at birth; help predict what babies are at increased risk for feeding problems; and help design better ways to manage feeding difficulties in babies. Pregnant women scheduled for ultrasound examination at the National Naval Medical Center in Bethesda, Maryland, or Georgetown University Hospital in Washington, D.C., are eligible for this study. Mothers will fill out a questionnaire providing general medical and health information. For the ultrasound procedure, a transducer (a small, wand-like device) is moved across the belly to produce images of the fetus. When the baby is awake and swallowing, images of the mouth, throat and air passages will be recorded on videotape. The movements associated with feeding-breathing, sucking, yawning and swallowing-will then be measured to document how swallowing develops. When the baby is born, researchers will review the medical chart for any findings relevant to this study. One to 2 weeks after delivery, the mother will be interviewed by telephone about the baby's feeding skills. Follow-up visits at 4 and 8 weeks after the birth will include observation of the baby's sucking and swallowing and an ultrasound examination, in which the transducer is held under the baby's chin during swallowing. Babies who show signs of slow sucking or swallowing development will have a follow-up examination at ages 4 and 8 months. Follow-up visits at 4 and 8 months after the birth will include observation of the baby's sucking and swallowing and an ultrasound examination, in which the transducer is held under the baby's chin during swallowing.

The purpose of this study is to test the reliability and validity of the T-MOE among pediatric patients with chewing disorders.

Multiple Sclerosis (MS) patients with subjective dysphagia will be tested for tongue strength fatigue using a strictly defined fatigue paradigm. A maximum of 40 sets will be performed, each set consisting of 5 repetitions of 80% of maximum isometric pressure (MIP) at the anterior tongue, followed by a MIP at the anterior tongue. Cut-off criteria are a MIP <50% of the baseline MIP, pronounced subjective discomfort and/or exceeding the allocated test time of 30 minutes.

The purpose of this study is to assess the association of genetic polymorphism such as the Brain-derived Neurotrophic factor (BDNF), in neurogenic dysphagia in those with brain lesion.

In many cases, the manometric examination is not feasible because of the pharyngeal sinusitis or pharyngeal torsion. In addition, although previous conventional manometry was used to estimate pharyngeal swallowing, the bolus flow transmission was still not evaluated, which still depended on the videofluoscopic swallowing studies. High resolution impedance manometry could help us to measure the bolus flow according to the impedance changes. However, the comparison between two approach methods of postoperative recovery of swallowing function is still inconclusive. The investigator aimed to examine the correlation between high-resolution manometric and videofluoroscopic measurements of the swallowing function.
