Active clinical trials for "Deglutition Disorders"

The purpose of this study is to develop an evaluation of dysphagia through deep learning-based video analysis in newborns and infants, and to report the correlation with future development.

The purpose of this study is to establish the highest dose of laser light for WST-11 VTP to treat obstruction from esophageal cancer that can be safely given.

This multi-site trial will follow a cohort of Veterans with dysphagia for 8 weeks as they undergo clinically guided oropharyngeal exercises with oropharyngeal strengthening as the primary goal. Veterans with dysphagia will be assessed at three time points: baseline, 4 weeks after treatment initiation, and 8 weeks after treatment initiation. A non-dysphagic Veteran control group will also undergo data collection at parallel time points, without completion of a treatment paradigm. The investigators will then compare patients to non-dysphagic controls using manometry, videofluoroscopy, diet assessment, functional reserve tests, and patient-reported outcome measures. The investigators aim to 1) quantify change in pressure measures of swallowing function resulting from dysphagia treatment; 2) determine which combination of standard of care and/or pressure-based metrics best track with outcome measures; and 3) develop multimodal prognostic algorithms that predict treatment success. This research will establish a precise outcome measurement paradigm suitable for dysphagia clinical care and research, thus improving clinical confidence and paving the way for a personalized medicine approach for dysphagia rehabilitation in Veterans.

To investigate the impact of physical therapy intervention of dysphagia on preventing pneumonia in acute stroke patients

To develop this objective and easily implementable assessment method of coughing based on acoustic features of voluntary and reflex coughs, there is a primary need in identifying and comparing acoustic cough features in healthy subjects and different disease-related coughs features. Cough is a common reason for seeking medical care. Chronic cough, defined as a cough that has lasted for longer that eight weeks, represents 10-38% of all referrals made to respiratory physicians [1-2]. Furthermore, between 60 and 80% of patients with chronic obstructivepulmonary disease (COPD) report cough. Following this pilot study comparing different populations, the applicability of the selected acoustic cough features should be examined in HNC patients with radiotherapy-induced dysphagia, Another frequent aspect of the clinical diagnostic examination of swallowing is perceptual analysis of voice quality immediately following deglutition. Changes in voice quality are assumed to provide information on the possible accumulation of saliva or food at the vocal folds level. It is reported that a change of voice may indicate laryngeal dysfunction or the presence of a foreign body at the laryngeal level [3] confirm that a normophonic voice after swallowing reflects a lack of aspiration-penetration. However, research shows that there is no strong correlation between aspiration and changes in perceptual voice quality (e.g. wet voice). A more reliable and easily implementable method could be detection of specific acoustic features of changes in voice quality.

The purpose of the study is to test a novel endotracheal tube support device that reduces pressure of the tube on the voice box for prevention of post intubation laryngeal symptoms including sore throat, change in voice and trouble swallowing.

The goal of this study is to investigate the therapeutic efficacy of repetitive transcranial magnetic stimulation (rTMS) and intermittent theta burst stimulation (iTBS) applying on suprahyoid motor cortex in chronic poststroke dysphagia, and its effect on hyolaryngeal movement. Participants will be randomized into three groups. The three experimental groups received either bilateral or ipsilateral rTMS, or iTBS (with contralateral sham stimulation) at suprahyoid motor cortex, while the placebo group received bilateral sham stimulation. Stimulation will be given at 5 hertz(Hz), 1000 pulses of rTMS or 600 pulses of iTBS per session, for a total of 10 sessions. The swallowing function, penetration-aspiration scale of video-fluoroscopic swallowing study, motor evoked potential of suprahyoid muscles, intraoral pressure, and ultrasound swallowing exam will be evaluated before therapy, and at 1, 3, 6 months post therapy.

This is prospective data recording study. All patients will receive standard medical care and no experimental interventions will be performed.

Although dysphagia is a known complication of cardiac surgery, risk factors and sensitive bedside clinical markers of dysphagia have not yet been identified. This longitudinal study will enroll 380 cardiac surgical patients and identify contributing risk factors of incident cases of dysphagia and identify sensitive bedside markers of dysphagia. Statistical modeling will produce two pragmatic clinical tools - a risk prediction model and a beside screening tool to improve care models.

This prospective, randomized, double blind, controlled study evaluates the effect of a single dose of perioperative IV steroid versus saline on swallowing after anterior cervical spine surgery
