Active clinical trials for "Deglutition Disorders"

This study is a pilot study to prepare clinical trials to evaluate the safety and effectiveness of 4-channel electric stimulation therapy devices as a newly developed function for the treatment of dysphagia disorders. The purpose of this study is to investigate the difference in effect by the electric stimulation method and to obtain the values such as mean, standard deviation and so on, and to determine the number of subjects to be studied for clinical trials of validation permission in the future.

The investigator proposes to study electrical activity reflective of esophageal motility in adults noninvasively by the use of multichannel electroesophagogram (EESG) and magnetoesophagogram (MESG) recordings.

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.

The purpose of this study is to show that the Per-Oral Endoscopic Myotomy (POEM) procedure is an effective treatment for people with achalasia.

This trial studies how well manual therapy works in treating fibrosis-related late effect dysphagia in head and neck cancer survivors. Manual therapy is the use of massage and stretching exercises to increase blood flow and muscle movement in the neck, throat, jaw, and mouth, which may help to improve swallowing ability and range of motion in participants who have had treatment for head and neck cancer.

The study aims to examine effectiveness of the Safe and Sound Protocol (SSP) on sensory, digestive, and eating behaviors in children currently receiving therapy.

The overall purpose of this study is to characterize the effect of probiotics on the oral microbiota in older adults with dysphagia at risk for pneumonia.

Suspension laryngoscopy (SL) is a surgical procedure that is widely applied in the diagnosis and treatment of many benign or malignant diseases of the vocal cords and allows bimanual surgery of the endolarynx (Larner et al., 2019). In suspension laryngoscopy, a significant force is exerted on the tongue and neck tissues due to the abutment mechanism used to visualize the larynx and pharynx, which are located deeper than the oral cavity. This force causes symptoms such as sore throat, dysphagia, paresis, cough, taste disorder, oral injury, and hoarseness in the postoperative period (Larner et al., 2019; Tsang et al., 2020; Taliercio et al., 2017).In the literature, it has been reported that patients experience sore throat, cough, dysphagia, and hoarseness symptoms after suspension laryngoscopy (Larner et al., 2019; Taliercio et al., 2017; Okui et al., 2020). Pharmacological and non-pharmacological methods can be applied to prevent sore throat and dysphagia after suspension laryngoscopy. The interventions that start while the patient is still in the recovery room to prevent postoperative sore throat and swallowing difficulties are the responsibility of the recovery unit nurses. Being aware of the problems such as sore throat and swallowing difficulties experienced by patients after suspension laryngoscopy, effective nursing practices should be developed to prevent these problems and their possible consequences. Therefore, the aim of this study is to examine the effect of cold vapor on sore throat and dysphagia in the early postoperative period after suspension laryngoscopy.

Dysphagia (swallowing impairment) is a serious health condition seen in many age-related disease and injury processes. Although videofluoroscopy (VF) is an international "gold standard" dysphagia diagnostic exam, there is a paucity of available normative physiologic VF reference values in healthy adults across the age span to guide interpretation of these examinations. In this project, the investigators will extend previous work on the quantitative measurement of swallowing physiology from VF examinations to establish reference values for swallowing in healthy adults, and to identify clinical decision point values for differentiating healthy swallowing across the age span from disordered swallowing in several high-risk clinical populations to study dysphagia.

Collection of basic data for real-time analysis and monitoring by measuring what changes in voice occur according to the state of dysphagia using voice analysis and various sensors.
