Filter by:Swallowing; It is a complex, dynamic, sensorimotor process involving more than 30 muscles located bilaterally in the oral, pharyngeal, and esophageal regions and involving the safe delivery of the food taken from the mouth to the stomach as a result of sequential and coordinated movements. The cervical region is important in terms of swallowing function, as it acts as a bridge between the oral and esophageal structures through the pharynx, hosts the larynx and upper respiratory tract, which plays an important role in safe swallowing, and contributes to the stabilization and preservation of posture thanks to the muscles in its structure. Craniocervical flexion (CCF) occurs at the atlantooccipital joint and upper cervical segments such as C1-2. While superficial muscles such as the SCM and anterior scalene muscles contract in cervical flexion, deep muscles such as the longus colli and capitis, which are mainly primary cervical stabilizer muscles, are activated in CCF. CCF is a movement felt as flexion in the upper part of the cervical region with a slight retraction of the chin. It is also known that the suprahyoid muscles are activated in CCF. Swallowing in the CCF posture has been shown to occur with less suprahyoid muscle activation. The cervical region must provide proper alignment, posture, and stabilization for effective and safe swallowing. Postural changes in the cervical region, and changes in the position of the hyoid bone cause changes in gravity, oropharyngeal structures, and muscle length-tension relationship, thereby changing the dynamics of swallowing function. Therefore, it is not possible to consider the cervical region separately from the swallowing function. However, the focus of the exercises to be chosen for the cervical region is different and the effects that are likely to occur may also be different. There is no study in the literature on the activation of superficial and deep muscles activated during swallowing of craniocervical flexion training exercises, which aim to improve cervical region mechanics by focusing especially on deep cervical flexors. The aim of this study is to investigate the effect of craniocervical flexion training (CCF) on swallowing-related structures in healthy individuals.
Swallowing is the delivery of food taken from the mouth to the stomach at an appropriate rate with the sequential movements of the structures in the oral, pharyngeal, and esophageal regions. The change in swallowing function due to structural and functional changes in the structures responsible for swallowing is called swallowing disorder (dysphagia). The treatment of neurogenic dysphagia aims to prevent complications such as dysphagia-related aspiration pneumonia, airway obstructions, and malnutrition, and to regulate swallowing physiology. Swallowing rehabilitation created for this purpose consists of compensatory techniques and rehabilitation methods. Compensatory techniques include changing the consistency and properties of food, postural changes, and increasing voluntary control. Rehabilitation methods consist of exercise-based methods such as oral motor exercises, Shaker exercises, and tongue strengthening exercises. In addition to these rehabilitation methods, it has been reported that neuromuscular electrical stimulation (NMES) positively affects swallowing function. It is known that cortical reorganization occurs due to sensory restimulation following the exercises performed in dysphagia rehabilitation. It has been reported that swallowing rehabilitation may also have positive effects on neural plasticity in patients with dysphagia. It is essential to transfer approaches that support neural plasticity to swallowing rehabilitation. The starting point of action observation therapy (AOT), which has just entered the literature, is based on motor learning-based approaches used in neurological rehabilitation, neural plasticity, motor imagery, and mirror neurons. Based on the fact that both motor image and movement observation can play a role in (re)learning motor control, AOT aims to provide activation of motor areas with movement observation and to develop a rehabilitation approach based on performing the observed actions. The AOT method consists of two stages. First, videos of the exercises to be done are created, and in the first stage, patients are asked to watch the video by focusing only on the video. In the second stage, patients need to practice the exercises they follow themselves. In this way, it is thought that the effectiveness of both motor learning will be increased. When studies on patients with neurogenic dysphagia are examined, the use of AOT, which is a new approach, in swallowing rehabilitation has not been found. Therefore, in this study, the creation of an AOT program based on mirror neuron and motor learning theory and its effect on swallowing function and quality of life related to swallowing will be examined in patients with neurogenic dysphagia. The investigators aim to increase the healing efficiency of the AOT program in patients with neurogenic dysphagia.
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.
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.
The present study was designed as a cross-sectional observational study providing the enrollment of tracheostomized patients undergoing major oncological surgery for head-neck cancer. Aims: - to provide objective data on the bolus transit during swallowing in tracheostomized patients with tracheal tube and without tracheal tube closing directly the tracheal stoma with a plaster, in order to sustain the choice to preserve the TT in dysphagic patients after oncologic surgery for more security during swallowing rehabilitation or adjuvant treatment. - to evaluate the features of swallowing, specifically bolus transit, in patients affected by head and neck cancer who underwent major oncological surgery.
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 or piperine and of central motor noninvasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) will be studied. Pairing sensory peripheral and central stimulation may produce greater benefits. The main aim of the project is to study the efficacy of a novel protocol of paired stimulation on acute PS-OD patients. The investigators will assess the acute application of tDCS/piperine or tDCS/capsaicin in the acute phase of stroke, will improve PS-OD. 2 days randomized crossover study with 60 patients in 3 treatment groups (60 patients in the acute stroke phase divided in 3 study arms). We will assess changes in swallow safety, and neurophysiology of the swallow, hospital stay, respiratory and nutritional complications, mortality and QoL.
Sarcopenic dysphagia is described as a swallowing disorder caused by a loss of muscle mass and strength, sarcopenia. It induces chronic complications like micro-inhalations and the worsening of chronic undernutrition, according to a vicious circle. Awareness of the high prevalence of sarcopenic dysphagia and its serious consequences among elderly people with disabilities and hospitalized patients is recent, which explains the low rate of screening in the population concerned. In this context, methods of prevention, evaluation and intervention of sarcopenic dysphagia adapted to the most exposed population are needed. Two European learned societies have developed recommendations that include increased awareness of swallowing disorders, the use of screening scores, preventive measures, diagnostic standardization, and implemented interventions (rehabilitation, textural adaptation, etc.). In order to respect these recommendations, a pedagogical sheet, entitled DYSPHAGING was elaborated within our unit in a multiprofessional way in 4 steps (1 - Screen; 2 - Protect; 3 - Confirm; 4 - Rehabilitate). This feasibility study aims to evaluate the rate of completion and the conditions for implementing steps 1 and 2 in hospital and institutional care units.
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.
This observational study aims to evaluate the psychometric properties of a new infant feeding tool called "SMART Tool" in the neonatal intensive care unit. The main questions it aims to answer are: 1. To design a feeding tool to assess oral motor and neurobehavioral skills in neonates 2. To establish psychometrics of the new tool by doing reliability and validity tests.
Severe Acquired Brain Injury (sABI), with a more or less prolonged state of coma, generally causes disruption of the physiological modes of swallowing and feeding and the physiological abilities of communication and phonation. There is broad agreement in the scientific literature for early intervention by the entire rehabilitation team. In the specific case of swallowing and phonatory function, speech therapist intervention is indicated with the goal of restoring the automatic and voluntary movements of the muscles involved in the performance of the previously mentioned functions. Speech-language treatment of buccal structures, sensation, motor and praxie is recommended in conjunction with other types of approaches (dietary modifications, compensation techniques, postural modifications). In the acute and early subacute phase of patients with sABI with a vigilance level of less than 4 according to the Levels of Cognitive Functioning scale, alterations in bucco-linguo-facial structures and swallowing can be observed that prevent the execution of a correct motor pattern of phonation and swallowing. For this reason, passive and/or active stimulation aimed at restoring sensitivity, strength, and movement coordination of the bucco-linguo-facial and laryngeal muscles is necessary to rehabilitate the prerequisites for the initiation of feeding, to restore adequate afferents, and to stimulate communication. A careful search of the literature shows that over the past decade many studies in the rehabilitation field have sought to understand the effects of local vibration therapy at various levels of the central nervous system and the possible benefits in neurorehabilitation. From a speech therapy perspective, there are only three studies on the area of dysphonia in cases of upper laryngeal nerve palsy, combining traditional treatment with the use of Novafon®, a sound wave medical device used for Local Vibrational Therapy. The results show greater improvements in vocal function and voice quality when classical treatment is combined with Local Vibrational Therapy. These studies conclude by affirming the need for further research with a larger sample size to analyze the potential effectiveness of Novafon® applied to the recovery of vocal cord paralysis.
