Active clinical trials for "Deglutition Disorders"

About 50% of people who have a stroke experience difficulty swallowing. There is a growing evidence base showing that swallowing therapy can help to improve swallowing, but we don't know which type or how much therapy is most beneficial. The investigators are further developing one particular intervention - swallow strength and skill training with biofeedback. This involves practicing strong or effortful swallows and practicing controlling the timing of swallowing using visual feedback on a screen showing the activity of the muscles involved in swallowing. The investigators want to know whether trained clinicians are able to deliver this therapy in acute hospital settings early after stroke. The investigators also want to explore whether there is an effect of dose in improving swallowing and other health factors. To do this the investigators will conduct a trial across several stroke units in the east midlands. The study aims to recruit 120 participants who have had a stroke and have dysphagia and who will randomly be placed in one of three groups. One group will get a standard dose therapy (10 x 35 minute sessions over 2 weeks), another group with receive a high dose therapy (20 x 35 minute sessions over 2 weeks) and the third will receive 'usual care' which is what they would usually get from their current service. The investigators will look at what therapy participants actually get, what factors might influence this and the training, support and conditions that enable clinicians to deliver the therapy. The investigators will also assess the participants swallowing and collect information on their health, face to face at the beginning and after the therapy and over the phone at three months.

This study is a randomized trial examining the impact of expiratory muscle strength training (EMST) on maintenance of safe and efficient oropharyngeal swallow function in persons with cancer of the head and neck (HNCA) undergoing treatment with radiation therapy or chemoradiotherapy (RT/CRT).

The study aims to adapt the Mealtime Assessment Scale (MAS) in a pediatric population in order to provide an observational tool compiled by swallowing professionals, in Italian, for the assessment of swallowing efficacy and safety during mealtime in an ecological setting, as mealtime administration occurs independently or by the caregiver.

The English version of the "Clinical Assessment of Dysphagia in Neurodegeneration" (CADN), represents a rapid and valid clinical assessment tool for dysphagia in neurodegenerative population. Currently, there is no validated tool in Italian specific for the clinical assessment of dysphagia in neurodegenerative disease with strong psychometric characteristics. The present study aims to translate and validate the Italian version of CADN in neurodegenerative population. Psychometric properties will be measured.

In a prospective, quantitative explorative study, the risk of aspiration and penetration when swallowing solid pills (placebo) compared to a crushed placebo pill will be evaluated during a routine Fiberoptic Endoscopic Evaluation of Swallowing (FEES). The study design is thus a quasi-experimental study design with repeated measurements in the sense of a pre-posttest. Each patient undergoes a baseline examination (routine procedure) followed by the intervention (administration of three different solid pills and a crushed pill).

Up to 84% of patients after stroke are accompanied by dysphagia, of which 53% are oral dysphagia. The oral phase is the initial phase of swallowing activity and the only stage of swallowing that is completely discretionary. Swallowing activity in the oral stage is not only related to the formation and push of food pellets, but also affects the continuity between the transition from spontaneous swallowing to the swallowing reflex.

The purpose of this research study is to figure out if there are physical factors such as cognition level, nutrition status, walking speed, and handgrip strength that are associated with the development of swallowing problems. Investigators want to better understand how swallowing problems develop in older adults with and without frailty. Identifying factors that contribute to swallowing problems, can develop therapies in the future to improve swallowing outcomes for older adults. This study will be done at the University of Wisconsin-Madison (UW-Madison). A total of about 69 people will participate in this study.

Dysphagia is a common problem in post-stroke patients and greatly impaired quality of life. Among them, the strength of tongue and lip muscles played a key role in the oral phase of swallowing and many stroke survivors suffered from these muscles weakness. Iowa oral performance instrument (IOPI) is a standardized portable device that can be used to quantify tongue muscle strength, thus allowing the clinician to set the level of resistance necessary to achieve optimal gains in strength, and also providing visual feedback of performance to the patients to guide training. In this study, we use Videofluoroscopic Swallowing Study (VFSS) to screen for the stroke patient suffering from dysphagia and recruited them into the trial. They then participated in a home based resistance-training program using the tongue depressor, 1 time everyday and each time consisted of 30 repetitions, totally 4 weeks. Various tongue strength variables and subjective scale were obtained before and after the intervention. The purpose of the study was to evaluate the effect of the home based swallowing therapy in the post stroke dysphagia patients.

The goal of this clinical study is to compare the effect of favourate taste stimulation of oral cavity and tounge, with sour and traditional single thermal stimulation in post-stroke patients with dysphagia. The main questions it aims to answer are: Whether favourate taste stimulation of oral and tounge is better than traditional thermal stimulation in improving swallowing function of patients with dysphagia. It has been reported that taste of sour stimulation can increase the frequency of swallowing. In this study, we want to know which is better for improving swallowing function between favourate taste stimulation and sour taste stimulation. Functional near-infrared spectroscopy (fNIRS) will be applied in this study to understand the neural mechanism of taste stimulation in improving swallowing function. Participants screened as post-stroke dysphagia will accept swallowing evaluation and fNIRS test before and after treatment. The treatment include taste stimulation and traditional swallowing training. Researchers will compare favourate taste stimulation with sour-taste stimulation and single thermal stimulation to see if the swallowing function improved faster and better in favourate taste stimulation group.
