The hypothetical role of congenital hypotonia in the development of early coronoid hyperplasia
2012
Abstract Background Coronoid hyperplasia (CH) is an abnormal bony elongation of a histologically normal coronoid process. Its definitive cause remains unknown. Objectives To analyze the possible implication of congenital hypotonia in the pathogenesis of early coronoid overgrowth. Patients and methods Two infants with congenital hypotonia were evaluated for limited mouth aperture. Bilateral CH was diagnosed. Transoral coronoidectomy was followed by an early dynamic physiotherapy program. Results Significant improvement of maximum interincisal opening was achieved. The review of the scientific literature proved the diagnosis of CH in the infant age group is extremely unusual and the etiology …
Intermittent Theta-Burst Stimulation Over the Suprahyoid Muscles Motor Cortex Facilitates Increased Degree Centrality in Healthy Subjects
2020
Theta-burst stimulation (TBS), a variant of repetitive transcranial magnetic stimulation (rTMS), can potentially benefit the treatment of swallowing disorders. However, the after-effects of TBS on the swallowing motor cortex remain uncertain. The newly developed graph-based analysis of the centrality approach has been increasingly used to explore brain networks. The purpose of this study was to identify degree centrality (DC) alterations in the brain network after different TBS protocols were performed over the suprahyoid muscles motor cortex in healthy subjects. A total of 40 right-handed healthy subjects (mean age: 23.73 ± 2.57 years, range: 21–30, 20 females) were included in this study …
The importance of the reproducibility of oropharyngeal swallowing in amyotrophic lateral sclerosis. An electrophysiological study
2017
Abstract Objective To investigate electrophysiologically the reproducibility of oropharyngeal swallowing in patients with ALS. Methods We enrolled 26 ALS patients, both with and without clinical signs of dysphagia, and 30 age-matched controls. The reproducibility of the electrophysiological signals related to the oral phase (electromyographic activity of the submental/suprahyoid muscles) and the pharyngeal phase (laryngeal-pharyngeal mechanogram) of swallowing across repeated swallows was assessed. To do this we computed two similarity indexes (SI) by using previously described mathematical algorithms. Results The reproducibility of oropharyngeal swallowing was significantly reduced both in…
Effects of Neuromuscular Electrical Stimulation (NMES) on salivary flow in healthy adults
2020
Background Neuromuscular electrical stimulation (NMES) is a method used for enhancing suprahyoid muscle activity and is widely applied as a treatment for dysphagia. Patients often complain of saliva pooling in the pharynx during NMES. Therefore, the purpose of this study was to investigate the changes in salivary flow during NMES. Material and methods Twenty healthy adults participated in this study. Electrical stimulation was applied at constant strength for 60 minutes to the suprahyoid muscles using VitalStim®. Participants were examined under three conditions of NMES: sensory threshold plus 75% of the difference between sensory and pain thresholds (75% Stim), SensoryStim, and Sham. Saliv…
