Filter by:In our study, our aim is to evaluate the effect of neuromuscular electrical stimulation added to traditional dysphagia therapy in stroke patients with dysphagia, on functional oral intake status, dysphagia-related symptoms, quality of life, and complications related to dysphagia.
Multiple Sclerosis is a chronic inflammatory autoimmune neurological disease characterized by the destruction of myelin in the central nervous system, grey matter and axonal loss. The prevalence of neurogenic dysphagia in this group of patients is estimated to be more than 30%. The aim of this study was investigating of Masseter, Orbicularis Oris, Sternocleidomastoid muscles' viscoelastic properties in MS patients with and without swallowing problems.
Swallowing impairment (dysphagia) is extremely common in older adults living with dementia due to age-related changes in swallowing and other disease-specific impairments. Dysphagia is commonly managed by modifying diet textures rather than engaging in rehabilitative swallowing therapy. This means that countless people with dementia are left to eat pureed foods and drink thickened liquids, which are unpalatable and lead to malnutrition. As the disease progresses, many are transferred to nursing homes. In Canada, speech-language pathologists, who manage dysphagia, are consultants within nursing homes; therefore, swallowing therapy is non-existent. However, exercise therapy is more commonly available. Rodent models have demonstrated that physical exercise strengthens tongue and vocal-fold musculature, which are critical components of swallowing. Therefore, it is possible that whole-body physical exercise, which increases rate of respiration, will help to strengthen swallowing-related musculature in older adults with dementia. In this study, older adults (65+) with early-stage dementia will complete a 12-week physical exercise program to determine improvement of swallowing function.
The prevalence of dysphagia in acute stroke patients undergoing transesophageal echocardiography (TEE) is unknown. The aim of this study was to assess for the first time whether TEE has a negative influence on swallowing in acute stroke patients.
The purpose of this study is to test the reliability and validity of the The Turkish Deglutition Handicap Index among adult patients with swallowing disorders.
This study will report the chewing and swallowing disorders of a Coffin-Lowry Syndrome (CLS) patient, and effects of chewing and swallowing training on chewing and swallowing function.
Study design: Multicenter, experimental, randomized, crossed, double blind study (patient and results analysis). Aim: To evaluate the effect of different neurostimulation techniques on the neurophysiological and biomechanical swallowing mechanisms of patients with dysphagia associated with chronic stroke and select those techniques with the best results to be evaluated in the second phase of the study (medium-term effects). Outcome measures: - Videofluoroscopy: prevalence of impaired efficacy and safety of swallow (penetrations and aspirations), penetration aspiration scale (PAS: from 0 to 8), biomechanical parameters (time to laryngeal vestibule closure, upper esophageal sphincter opening). - Pharyngeal sensory evoked potentials (pSEP): latency and amplitude of obtained evoked potentials. Higher latency (0 onwards) means worse outcome and higher amplitude (0 onwards) means better outcome. - Pharyngeal motor evoked potentials (pMEP): latency, amplitude, duration and area of obtained evoked potentials. Higher latency (0 onwards) means worse outcome and higher amplitude (0 onwards) means better outcome. Treatments and patients: 36 post-stroke patients with oropharyngeal dysphagia (PAS superior or equal to 2) randomized patients in 3 treatment arms (3 groups of 12 patients). - Active and sham repetitive transcranial magnetic stimulation (rTMS): 90% of the resting motor threshold, 1250 pulses, 5 Hz. - Active and sham Intrapharyngeal Electrical Stimulation (PES): 75% of tolerance threshold, pulses of 0.2 ms, 5 Hz, 10 min. - Oral Capsaicin (active intervention, 10-5M, TRPV1 agonist) and placebo solution (sham): 100 mL, single administration. Administration of study therapies: The study will be performed in two visits separated for one week. In each visit patients will randomly receive active or sham treatment and a pre-post evaluation of biomechanics of deglutition (with VFS) and neurophysiological mechanisms (swallowing afferent and efferent pathways) will be performed in each visit. Acute randomized administration -> 1 active session (pre/post evaluation with VFS/pSEP/pMEP) + 1 separate control session 1 week apart (pre/post evaluation with VFS/pSEP/pMEP).
Transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS) are two (CE marked medical devices) new, non-invasive (over the scalp) brain stimulation (NIBS) techniques. Both tACS and tRNS deliver a weak current continuously across the brain using pads placed over the scalp, which has been shown safe and well-tolerated by healthy adults and patients. These two techniques are able to softly alter physiological function within the brain. tACS can influence the brainwaves which have been demonstrated to play important roles in movement, sensation, and thinking functions. tACS and tRNS have been investigated for several years and have been shown to be safe, well tolerated and produce beneficial results in hand movement, hearing, and working memory. Swallowing problems are life-threatening symptom among patients with brain impairments and elderly people. Until now, there are no studies investigating whether tACS and tRNS can have a beneficial effect on swallowing function in human. Our aim is to examine the effects of different strengths of tACS and tRNS to determine the best approach for brain stimulation that controls swallowing action, before using these techniques in patients with (neurological) swallowing disorders. Participants: Healthy adults who are aged 18 years old or above with no medical complications or significant past medical history will be recruited in the study.
The purpose of this study is to test the reliability and validity of the The Turkish Oropharyngeal Dysphagia Screening Test for Patients and Professionals among adult patients with swallowing disorders.
Swallowing function is controlled by two swallowing centres (one on each half of the brain). There is a dominant and non-dominant swallowing centre. Damage to any part of the brain can lead to swallowing problems, for example in strokes. Recovery of the ability to swallow is associated with increased activity (compensation) over the undamaged centre. The cerebellum is an area of the brain involved in the control and modulation of muscle movements. It is found at the back of the skull. Over the past few years studies have tried to improve swallowing function using techniques to stimulate regions of the brain and encourage compensation. Repetitive transcranial magnetic stimulation (rTMS) is a technique which can temporarily increase or suppress activity over regions of the brain. This study will use cerebellar rTMS to attempt to increase activity over the cortical swallowing centres. It will also temporarily suppress activity over the dominant swallowing centre (a virtual lesion) before using cerebellar targeted rTMS to attempt to reverse this suppressive electrical and behavioural effect. The investigators aim to compare the effectiveness of rTMS over the two halves of the cerebellum to rTMS over one half of the cerebellum in increasing activity over the swallowing centres and reversing the suppressive effects of low frequency rTMS 'virtual lesion' over the dominant swallowing centre.
