Active clinical trials for "Deglutition Disorders"

The aim of the study is to evaluate whether the effect of biofeedback treatment is more effective than a control treatment in the recovery of dysphagia. This study will be a multicentric randomized, single-blind controlled study. The investigators intend to recruit 100 patients who have suffered a stroke and have dysphagia. Fifty patients will undergo training with bio-feedback (experimental group) and the other fifty patients will undergo standard training, using only verbal feedback rather than visual feedback (control group). Our hypothesis, based on the results obtained in some previous studies, is that in the control group the efficacy of the treatment will be lower in the absence of immediate visual feedback of strength, timing, coordination and efficacy of the swallowing act.

The goal of this clinical trial is to clarify which biomechanical aspects of swallowing are altered by Pharyngeal Electrical Stimulation (PES) in stroke patients and healthy volunteers. The peripheral effect of PES intervention on the biomechanics of swallowing will be evaluated with High Resolution Manometry Impedance (HRMI).

The traditional Chinese medicine rehabilitation for post-stroke dysphagia impairment will be intervened, which can promote the recovery of dysphagia function of stroke patients, reduce the disability rate and improve the quality of life.

Swallowing impairments (dysphagia) frequently occur after stroke and have devastating consequences on overall health and quality of life, and long-term deficits in swallow function also increase risk of morbidity (e.g. depression) and mortality (i.e. aspiration pneumonia). As such, rehabilitation of swallow function to improve safety and efficiency of swallowing is essential in this population. This study aims to: 1) Provide preliminary data to evaluate the effect of a novel lingual endurance exercise on swallow function in individuals with post-stroke dysphagia; and 2) Collect preliminary data regarding changes in white matter tract diffusion and cortical thickness and from MRI data to better understand effects of lingual exercise training on neuroplasticity.

Esophageal cancer is the seventh most common type of cancer in the world, with an estimated global incidence of 604,100 new cases per year. The main symptom of esophageal cancer is dysphagia, associated or not with weight loss. Unfortunately, due to asymptomatic presentation in the early stages, more than half of patients are diagnosed in advanced stages of the disease, becoming ineligible for treatment with curative intent. In this sense, chemotherapy and radiotherapy are the pillars of palliative treatment, often regressing the injury and improving symptoms. However, some patients persist with dysphagia. In this scenario, esophageal prostheses are one of the main tools in the palliative treatment of esophageal cancer dysphagia, obtaining rapid and lasting relief of dysphagia. This study aims to compare fully covered (FC-SEMS) and partially covered (PC-SEMS) esophageal prostheses in this context, evaluating the number of reinterventions in each group, as well as the occurrence of adverse events. However, it is expected that with the data obtained it is possible to develop clearer and more effective protocols in the palliation of malignant dysphagia of esophageal stenosis.

According WHO, oropharyngeal dysphagia (OD) is a prevalent post-stroke (PS) condition involving the digestive system (ICD-10: I69.391) and an independent risk factor for malnutrition and pulmonary infection; and leads to greater morbimortality and healthcare costs and poorer quality of life (QoL). Currently, OD therapy is mainly compensatory, with low rates of compliance and small benefit, and there is no pharmacological treatment, so new treatments that improve patients' condition are crucial. PS-OD patients present both oropharyngeal sensory and motor deficits, so neurorehabilitation treatments which target both could be optimum. Benefits of paired peripheral sensory stimulation with oral capsaicin and of central motor noninvasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) will be studied. Pairing pharmacological peripheral and central stimulation may produce greater benefits. The main aim of the project is to study the efficacy of two novel protocols of paired stimulation on PS-OD patients. The investigators will assess whether 5-day application of tDCS/capsaicin or rTMS/capsaicin in the chronic phase of stroke, will improve PS-OD. One RCT (200 patients in the chronic stroke phase divided in 4 study arms) will assess changes in swallow safety, biomechanics and neurophysiology of the swallow response, hospital stay, respiratory and nutritional complications, mortality and QoL.

The purpose of this research project is to investigate the incidence of impaired swallowing (dysphagia) after anterior cervical spine surgery (ACSS) and to study the long-term effect of dysphagia on nutritional status 12 ± 3 months later. Furthermore, to investigate the effect of a new rehabilitation method for dysphagia among individuals with swallowing dysfunction after ACSS.

This study is to assess the efficacy of intraoperative intravenous nonsteroidal anti-inflammatory drug (ketorolac) versus intravenous (dexamethosone) administration on dysphagia and dysphonia after ACDF.

Dysphagia in patients with stroke, multiple sclerosis, parkinsonism or dystonia can occur due to relative hypertonia of the cricopharyngeus muscle. In the resting state, muscle is contracted and relaxes only during deglutition. Treatment of dysphagia by injecting botulinum toxin in the cricopharyngeus was described by Schneider et al. in 1994. More than 100 cases have been described after that, however there are no randomized controlled trials. A meta-analysis from Cochrane has also concluded that there is no sufficient evidence to conclude regarding the efficacy and safety of Botulinum toxin injection in cricopharyngeal dysfunction. So this study is necessary to fill this void in knowledge

The overall purpose of this project is to develop effective dysphagia rehabilitative interventions for patients with Alzheimer's Disease and related dementias at risk for pneumonia development.
