Filter by:The purpose of this study is to evaluate whether electrical pharyngeal stimulation in addition to standard care can enhance short-term swallow recovery in tracheostomized dysphagic stroke patients and thereby facilitate earlier decannulation compared to sham treatment plus standard care.
This study is designed to investigate the treatment efficacy of 8 weeks swallowing exercise programs for patients with NPC after radiation therapy. This study also compares two different swallowing exercise: effortful swallow and Mendelsohn's maneuver, to see which one can bring more benefits to patients after a certain period of exercise training. Three assessment tools are selected to evaluate the study result: Mann Assessment of Swallowing Ability (MASA), videofluoroscopic swallowing study (VFSS), and Chinese version Swallowing Quality-of-Life Questionnaire (CSWAL-QOL). The hypothesis of this study is that the effortful swallowing exercise would have better treatment efficacy.
Swallowing difficulties are common after a stroke and can lead to serious complications like pneumonia and malnutrition. Unfortunately, there are no effective treatment for improving swallowing in stroke patients. Previous investigations have shown that recovery of swallowing functions occurs from reorganization ("rewiring") of the non-involved cerebral hemisphere. In this study, the investigators propose to investigate a new intervention, which combines, swallowing exercises with brain stimulation targeted to the non-involved cerebral hemisphere, using low intensity current in acute stroke patients. The investigators plan to assess the safety of this technique in this patient population and also assess its effect on improving swallowing functions and swallowing physiology. During this time trial participants will undergo standardized swallowing and neurological assessments as well as brain MRI scans.
The purpose of this pilot study is to find out if adding triamcinolone (steroid) injection at the participant's initial esophagogastroduodenoscopy (EGD) procedure will improve the opening of their esophagus and decrease the need for repeat dilations.
The purpose of this study is to determine whether a novel edible nutritious gel for patients with chewing and swallowing difficulties, Nutri-jelly, is effective in improving the quality of life of head and neck cancer patients while undergoing conventional radiotherapy.
The purpose of this study is to see if cold liquids improve the swallowing mechanisms in premature infants with swallowing difficulties (dysphagia). The only way to objectively diagnose dysphagia is by having that infant undergo a Video Fluoroscopic Swallow Study (VFSS), which allows direct visualization of the liquid bolus (barium) in real time. Infants suspected of having dysphagia and who are referred for a VFSS will be recruited for this study. Once consented, the infant will undergo a standard VFSS. If that infant is diagnosed with dysphagia, the study protocol will begin by keeping the infant the same position and feeding them cold liquid barium from an identical bottle. A total of 5 swallows will be visualized, which adds approximately 5-10 seconds to the study. Both the standard swallows and the study swallows will be recorded for analysis and comparison. It is hypothesized that the study swallows will have less deficits than the standard swallows. If an infant's standard VFSS does not indicate dysphagia, that infant will no longer be eligible for this study.
Oropharyngeal dysphagia (OD) is a major complaint among many patients with stroke and causes severe complications. There is no specific treatment for these patients. Impaired swallow response is caused by a delay in the timing of oropharyngeal reconfiguration with delayed airway protection. Swallow response is initiated by sensory afferent fibers in the oropharynx and cerebral cortex reaching the central swallowing pattern generator (CPG) in the medulla oblongata and brainstem motor nuclei. Hypothesis: Stimulation of pharyngeal sensory afferent fibers through TRPV1 receptors and electrical stimuli might enhance the stimulation of the CPG and speed the swallow response. Long-term treatment of OD will improve clinical outcome of stroke patients. Aim: To assess the effect of TRPV1 agonists (capsaicin) and that of sensorial pharyngeal electrical stimulation (intrapharyngeal and transcutaneous) on VFS signs and swallow response at 3, 6 and 12 months after treatment in stroke patients with established OD. To compare the clinical effect of classical rehabilitation strategies with that of these new afferent sensorial neurostimulation strategies in terms of nutritional status parameters, incidence of aspiration pneumonia and/or low respiratory tract infection, quality of life, and mortality. Methods: Clinical screening of OD with the volume-viscosity swallow test and assessment by VFS and quantitative measurements of swallow response. Randomized controlled trial assessing the effect of standard rehabilitation with that of afferent sensorial neurostimulation strategies.
This study will evaluate with videofluoroscopy (radiologic method to study the deglutitive physiology) the effect on the deglutition of two therapeutic treatments with the duration of 2 weeks, based on the increase of the sensorial stimuli in older patients with oropharyngeal dysphagia: 1. Stimulation of Transient Receptor Potential Vanilloid 1 (TRPV1) oropharynx chanels using a natural agonist administrated in the alimentary bolus. 2. Stimulation of the sensorial neurons of the pharynx and larynx using transcutaneous electrical stimuli. Moreover, with an electroencephalographic study we will assess the effect of both treatments in the cortical neuroplasticity.
In the acute phase of stroke, dysphagia (difficulty/inability to swallow) is a common problem that can have serious consequences such as aspiration pneumonia, increased lenght of hospitalisation, and death. It would be interesting to enhance the therapeutic effect of swallowing retraining by means on non-invasive brain stimulation such as transcranial direct current stimulation (tDCS). Hypothesis: during the acute phase of stroke, applying tDCS over the brain during the revalidation and/or supervised feeding improves dysphagia significantly when compared to sham tDCS.
This randomized pilot clinical trial studies dexamethasone in reducing oral pain and dry mouth after surgery in patients with oropharyngeal cancer. Dexamethasone may help lower pain and dry mouth caused by surgery.
