Filter by:The facial paralysis is a frequent disease causing important functionals swallowing dysfunctions. The purpose of our study was to evaluate the improvement of the swallowing disorders after surgery by lengthening temporalis myoplasty (LTM) in the facial paralysis. This prospective study has realised on the following of patients affected by facial paralysis treated by LTM. Self-administered questionnaires and clinics tests had realized to analyze three components oh the oral phase of the swallowing ( drooling, mastication and handicap). The evaluations was realized before the surgery and at 3 and 6 months after .
The study is designed to explore the effectiveness of non-invasive cerebellar stimulation to enhance motor plasticity in the cortex after stroke. The investigators have shown that the human cerebellum is strongly activated during the act of swallowing and when stimulated with single TMS pulses can strongly facilitate the corticobulbar projection to the pharynx in humans. More recently the investigators have identified the most relevant frequency of stimulation of the cerebellum that can produce longer term excitation in the human swallowing motor system. The investigators therefore believe that the potential for cerebellar stimulation in improving swallowing is much greater than other methods for two reasons. Firstly, previous work has shown that unlike successful recovery of hand/arm function which relies on restoring activity in the stroke hemisphere, recovery of swallowing function relies on increased excitability in intact projections from the non-stroke hemisphere. The investigators believe that methods that can enhance these undamaged pathways have a greater chance of inducing recovery in the human swallowing system in unilateral stroke. Additionally cerebellar stimulation produces very high levels of corticobulbar excitation it may also have the advantage of improving dysphagia in posterior fossa strokes. Second, the human cerebellum is relatively easy to target and stimulate and has reduced risk of inducing unwanted effects (such as seizures) which as a consequence makes cerebellar stimulation a more pragmatic method for delivering therapeutic neurorehabilitation to dysphagic stroke patients compared to other more complex/riskier methods. A final factor is that the investigators have developed a "virtual lesion" model of swallowing dysfunction in healthy volunteers which can be reversed quite successfully with other neuro-stimulation protocols. The investigators can therefore use this model to test the effectiveness of cerebellar stimulation protocols (ipsilateral and contralateral cerebellar sites) before choosing the most effective side to apply stimulation in a proof of principle trial/study in a small group of sub-acute dysphagic patients. The hypotheses are that cerebellar TMS will: i. Reverse the brain inhibition and behavioural dysfunction following a virtual lesion model of disrupted swallowing in healthy brain (phase 1); ii. Reduce the degree of aspiration in acute dysphagia after a stroke (phase 2).
Few existing data currently indicates that anti-inflammatory drugs could help diminish the local cervical inflammation tough to cause the dysphagia, hoarseness and dyspnea after an anterior surgical approach to the spine. This study aims to evaluate the effect of high dose of steroids on dysphagia after an anterior cervical spine procedure. Patients subjected to a cervical spine surgery through an anterior approach will be randomized to a treatment group receiving 3 doses of IV dexamethasone (decadron) and a placebo group receiving saline. Outcome will be measured with dysphagia scales, modified barium swallow and rhino-pharyngo-laryngoscopy, all done pre and post-operatively. Secondary outcomes involve neurological condition, pain and fusion rate.
This study will explore the effects of 3 different neurostimulation methods on swallowing function in patients with dysphagia secondary to Parkinson's Disease
The primary purpose of the study is to evaluate whether the effect of bio-feedback dysphagia treatment is more effective than a control treatment in post-stroke patients. This study will be a randomized, single-blind controlled pilot study. The investigators intend to recruit 40 patients who have suffered a stroke and have dysphagia. Twenty patients will undergo training with bio-feedback (experimental group) and the other 20 patients will undergo standard training, using only verbal feedback rather than visual feedback (control group). The authors hypothesize that in the control group the efficacy of the treatment will be lower in the absence of immediate visual feedback of strength and coordination of the swallowing act.
This study will test prucalopride (a prokinetic drug currently approved by Health Canada for treatment of constipation) as a treatment for Ineffective Esophageal Motility (IEM). Adult patients with previously diagnosed IEM will be invited to participate by the investigators. The participants will take the study medication for 5 days and on the final day of medication undergo an esophageal manometry procedure at the Calgary Gut Motility Centre to measure esophageal function. Symptoms and side effects will be tracked at baseline and on Day 5.
The aim of the study is to investigate the relationship between dysphagia symptom severity and quality of life of the patients with neurogenic dysphagia.
The prevalence of chewing dysphagia in the domestic rehabilitation department ward was about 53.61%.Nasal tube retention of about 31%, due to nasogastric tube feeding, often overlooked oral hygiene, easy to cause respiratory tract infection. At the same time, oral hygiene will also affect the effectiveness of swallowing treatment, is worthy of attention to health problems.
For individuals with neurodegenerative conditions, such as Amyotrophic Lateral Sclerosis and Parkinson disease, swallowing impairment (i.e., dysphagia) is a common and serious symptom. Dysphagia places the affected individual at risk for secondary health consequences, including malnutrition and aspiration pneumonia, and negatively affects quality of life. Thickened liquids are commonly recommended for individuals with dysphagia, as they flow more slowly and reduce the risk of entry into the airway. However, there is limited understanding about how changes in liquid thickness modulate swallowing physiology in individuals with neurodegenerative conditions, and previous reports have shown that increased liquid thickness may contribute to the accumulation of residue in the throat. The purpose of this study is to explore swallowing physiology and function in individuals with neurodegenerative conditions, across five levels of liquid thickness (thin, slightly-thick, mildly-thick, moderately-thick, and extremely-thick), and to identify boundaries of "optimal liquid thickness", which maintain airway safety, without contributing to the accumulation of significant residue. Results from this study will help guide the clinical recommendations for thickened liquids in dysphagia management.
Dysphagia is the major symptom of patients with malignant esophageal stricture caused predominantly by advanced esophageal cancer. Stent placement is the most commonly used strategies for relieving the dysphagia and a novel irradiation stent loaded with 125I seeds has recently been developed. A multicentre randomized clinical trial demonstrated this irradiation stent can relieve the dysphagia rapidly and prolong the survival of patients with advanced esophageal cancer, but the total stent stenosis rate cannot be ruduced. A novel fully covered segmented retrievable irradiation stent was developed in our institute. The purpose of this study is to evaluate the safety and clinical efficacy of this newly developed irradiation stent in patients with unresectable malignant dysphagia.
