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.
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.
Aim of this study is to evaluate swallowing functionality in patient sedated for gastroenteric endoscopic procedure. Swallowing will be study by laryngeal fibroscopy and evaluate using Penetration-Aspiration Scale and Aspiration Risk validated in scientific literature. Aim of the study is to describe swallowing, as an expression of airway protection, in sedated patient. in particular, our purpose is to determine the incidence of moderate-severe and severe swallowing alteration (level 3 or 4 of Aspiration Risk scale).
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 is a device evaluation study to determine the optimal stimulation characteristics for using vibrotactile stimulation as a sensory triggering device for self retraining in patients with chronic moderate to severe dysphagia. Stimulation characteristics to be tested are frequency of vibration, pressure between the device and the skin, mode of vibration (pulsed or continuous).
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.
The goal of this study is to obtain data that well help inform the feasibility and design of a randomized control trial of the therapeutic Neuromuscular Electrical Stimulation (NMES) technique in improving the swallowing function of young infants presenting with severe dysphagia.
The purpose of this study is to compare IV acetaminophen to oral acetaminophen for pain control in children undergoing tonsillectomy with or without adenoidectomy.
Study hypothesis: ALTENS techniques, administered within the first 3 months after radiation completion, can improve radiation-induced dysphagia and associated symptoms in head and neck cancer patients. This beneficial effect is mediated by the reduction of chronic inflammatory response of swallowing musculature to radiation, consequently a reduction in muscle fibrosis. Primary study objective: To evaluate the effectiveness of ALTENS in relieving radiation-induced dysphagia. Eating Assessment Tool (EAT-10) scores will be used for this primary study endpoint.
