“…Studies of 'neurogenic dysphagia' typically include heterogeneous subject groups, including subjects with cerebrovascular accident (CVA), progressive neurological diseases, brain tumors as well as TBI [19,20]. Some studies involving TBI subjects even include other subjects with head and neck cancers [21] and dysphagia due to other structural/anatomical issues [22]., The majority of research into neurogenic dysphagia has, however, focused on subjects with CVA [23 •• , [24][25][26][27].…”

Dysphagia is a common morbidity and cause of mortality following traumatic brain injury (TBI). Despite this, there is a paucity of evidence demonstrating the efficacy of dysphagia management strategies and treatments in this population. Typically, subjects with dysphagia following TBI are placed into non-specific 'neurogenic' dysphagia subject groups, which include subjects with degenerative neurological diseases, neurological cancers, and cerebrovascular accident. However, dysphagia following TBI has a multifactorial presentation, with causative and contributory factors including cognitivecommunication, behavioral, neurological, and mechanical issues. As such, the management for dysphagia post-TBI must be multifactorial, team-based and involve the patients' families and carers. Much of the research regarding the management and treatment of dysphagia in general is in its infancy: larger and more rigorous studies are required to demonstrate treatment efficacy. More studies specifically examining dysphagia and its management in the TBI population are required to ensure the future efficacy and accuracy of treatment.

“…While some studies 1,3,[8][9][10][11][12][13][14][15][16] show benefits in the pathophysiology of swallowing in patients with oropharyngeal dysphagia submitted to NMES, others [5][6][7] report the absence of physiological and functional changes resulting from these stimuli. It must be said that even the publications that demonstrate positive results present questionable methodological designs in scientific relevance.…”

“…The scientific literature about the therapeutic effectiveness of NMES in dysphagia is still controversial, lying since studies [5][6][7] that does not correlate improvement of biomechanic of swallowing as a result of its use, as well as studies that verified this biomechanic optimization and, consequently of dysphagia 1,3,[8][9][10][11][12][13][14][15][16] .…”

Purpose: the purpose of this study is to verify the effect of Neuromuscular Electrical Stimulation on the suprahyoid muscle activity during swallowing, in post stroke subjects, with oropharyngeal dysphagia. Methods: participated eight post-stroke subjects with dysphagia, male and female, referred to speech--language therapy to early swallowing rehabilitation. Before the first rehabilitation session, the patient´s muscular electrical activity of suprahyoid muscle was measured using Surface Electromyography Biofeedback. Patients were randomly divided into two groups: Experimental Group (n=4): patients who received both traditional speech-language therapy and the application of Neuromuscular Electrical Stimulation. Control Group (n=4): patients submitted to traditional speech-language therapy. After eight sessions, all patients measured the suprahyoid activity with the Surface Electromyography Biofeedback. The pre and post treatment results were compared in both groups. Results: comparing the two groups average of time and amplitude of the muscle contraction during swallowing of saliva and two swallows of paste, no statistically significant differences were observed in the pre and post treatment values. Conclusion: the use of Neuromuscular Electrical Stimulation on the parameters and methodology used did not prove efficient in promoting greater contraction of the suprahyoid muscles during the swallowing, in post-stroke individuals with oropharyngeal dysphagia. The data obtained may be due to the methodology used in this study relative to the protocol application and the way to measure the results.

Métodos: participaram da pesquisa oito indivíduos pós-Acidente Vascular Cerebral com disfagia, de ambos os sexos, encaminhados para terapia fonoaudiológica com objetivo de trabalhar a função da deglutição, em início de processo terapêutico. Anteriormente ao início da primeira sessão, foi realizada a mensuração do tempo e amplitude da atividade elétrica muscular através da Eletromiografia de Superfície de Biofeedback. Os pacientes foram divididos aleatoriamente em dois grupos: Grupo Experimental (n=4): pacientes que receberam a fonoterapia tradicional e aplicação da Eletroestimulação Neuromuscular; Grupo Controle (n=4): pacientes que receberam a fonoterapia tradicional. Após oito sessões, todos os pacientes passaram novamente pela Eletromiografia de Superfície de Biofeedback para verificar a atividade elétrica da musculatura supra-hióidea. Os registros dos exames pré e pós intervenção foram comparados nos dois grupos. Resultados: comparando-se as médias das variáveis de amplitude e tempo da atividade elétrica muscular durante a deglutição de saliva e nas duas deglutições de pastoso, não foram obse...

“…In VitalStim therapy electrodes are simultaneously activated over the submental and laryngeal regions, with the aim of stimulating a simultaneous contraction of the mylohyoid in the submental region (to elevate the hyoid bone) and the thyrohyoid in the neck (to elevate the larynx to the hyoid bone) (Ludlow et al, 2006) [14].…”

Aim: Of our study is to evaluate the efficacy of transcutaneous electrical stimulation (Vitalstim therapy) to treat patients with dysphagia and to determine the impact of the modified barium swallow study (MBSS) on patient management. Material and methods: From June 2014 to April 2016, seventy three patients with dysphagia were included. All the patients underwent pre vitalstim-therapy evaluation by speech-language pathologists, including clinical evaluation of swallowing and modified barium swallow study (MBSS). In MBSS we evaluate the following, delay in oropharyngeal swallowing phase, closure of epiglottis, laryngeal elevation, passage of contrast behind the epiglottis that denoting penetration, presence of aspiration and presence residual barium after swallowing. After VitalStim therapy, all patients underwent MBSS assessments and also underwent a follow up survey months (range, 1 to 6 months) after their therapy to assess whether the improvement was worthwhile and sustained. Results: In our study our 73 patients showing radiological findings denoting neurological swallowing disorders, 65 patients (89%) showing delay in oropharyngeal swallowing phase, weak laryngeal elevation found in 58 patients (79%) , 68 patients (93%) showing aspiration and 70 cases (96%) showing penetration and incomplete closure of the epiglottis. Presence of residual barium after swallowing within the vallecula was seen in 68 patients (93%). 52 of the 73 patients (71%) showing complete improvement at first follow up study after VitalStim therapy. 21 of the 73 patients (29%) showing some improvement and need another therapy sessions and in the next follow up study 15 cases showing complete improvement. However, 7 cases of the 21 patients having severe dysphagia before therapy, only 2 of 7 showed any improvement, and these patients still required a feeding tube for adequate nutrition, however, the 5 of 7 showing complete improvement after another session of therapy. Conclusion: We conclude that the modified barium swallow is valuable in the rehabilitation of patient with swallowing disorders helps speech pathologist to identify and modify swallowing abnormalities as well as management program. We also conclude that VitalStim therapy is effective and safe in the treatment of patients suffering with the swallowing difficulties.
