Spinocerebellar ataxia: Functional analysis of the Stomatognathic System.
Medicina Oral Patologia Oral Y Cirugia Bucal, 2019Co-Authors: B. Ferreira, Marcelo Palinkas, Lucyanna Campos Goncalves, Veridiana Wanshi Arnoni, Isabela Hallak Regalo, Paulo Batista De Vasconcelos, Washigton Luiz Gomes De Medeiros Junior, Jaime Eduardo Cecílio Hallak, G Silva, Simone Cecilio Hallak RegaloAbstract:BACKGROUND: Neurodegenerative diseases that affect the cerebellum, especially in elderly individuals, cause impairment of motor coordination and quality of life. The presente study evaluated the electromyographic activity and thickness of the right and left masseter and temporal muscles, and the maximum molar bite force of individuals with spinocerebellar ataxia. MATERIAL AND METHODS: Twenty-eight individuals were divided into two groups: those with (n=14) and without (n=14) spinocerebellar ataxia. Data on the masticatory muscles obtained from the electromyographic activity (resting, right and left laterality and protrusion), muscle thickness (maximal voluntary contraction and tensile strength) and maximum bite force (right and left) were tabulated and descriptive analysis using Student's t-test (P ≤ 0.05). RESULTS: In the comparison between groups, greater electromyographic activity was demonstrated for individuals with spinocerebellar ataxia, with a statistically significant difference in protrusion and laterality for the temporal muscles (P = 0.05). There was no statistically significant difference between the groups for masticatory muscles thickness in the conditions evaluated. For maximum molar bite force, the group with spinocerebellar ataxia showed lower bite force (P ≤ 0.05). CONCLUSIONS: The data obtained suggest that spinocerebellar ataxia promotes functional reduction in the Stomatognathic System, mainly affecting the electromyographic activity and bite force, hindering chewing, with a resultant alteration of nutritional intake and a decrease of quality of life.

Material and methods Thirty individuals enrolled in the study were divided into the study group (with ALS, n=15) and control group (healthy individuals, n=15). Data regarding molar bite force (right and left), electromyographic activity (mandibular rest, right and left laterality, protrusion, and maximum voluntary contraction), chewing efficiency (habitual and non-habitual), and masticatory muscle thickness (rest and maximum voluntary contraction) were tabulated and subjected to statistical analysis (Student's t-test, p≤0.05). Results Comparisons between the groups demonstrated a statistically significant increase in the electromyographic activity of the right masseter (p=0.03) and left masseter (p=0.03) muscles during mandibular rest; left masseter (p=0.00), right temporalis (p=0.00), and left temporalis (p=0.03) muscles during protrusion; and right masseter (p=0.00), left masseter (p=0.00), and left temporalis (p=0.00) muscles during left laterality, in individuals with ALS as compared with healthy individuals. A statistically significant decrease was observed in the habitual chewing efficiency of the right masseter (p=0.00) and right temporalis (p=0.04) muscles in individuals with ALS. No statistically significant difference between the groups was found the masticatory muscle thickness and maximal molar bite force. Conclusions ALS may lead to modifications in the activities of the Stomatognathic System, including muscular hyperactivity and reduction in chewing efficiency; however, no change has been observed in the masticatory muscle thickness and molar bite force.

Journal of electromyography and kinesiology : official journal of the International Society of Electrophysiological Kinesiology, 2015Co-Authors: Gabriel Pádua Da Silva, Paulo Batista De Vasconcelos, Selma Siéssere, Marisa Semprini, Alcyone Artioli Machado, Bruno Ferreira, Edson Donizetti Verri, Camila Roza Gonçalves, Maria Aparecida Carneiro Vasconcelos, Simone Cecilio Hallak RegaloAbstract:Abstract Purpose : To understand the effects of HIV type 1 on the function of the masticatory muscles. Methods : Sixty individuals were selected from both genders, aged between 22 and 57years (mean 36.77±9.33years), and divided into two groups: Group HIVG, 30 individuals with HIV subtype 1, and Group CG, 30 healthy individuals (control group). The individuals were submitted to assessments of their masticatory muscle activity, biting strength and thickness of the masticatory muscles by means of electromyography, maximal molar bite force and ultrasound imaging, respectively. The resultant data were statistically analyzed by t -tests ( p Results : The HIVG normalized EMG data from a mandibular rest position, protrusion, right and left laterality movement of the jaw showed that HIVG presented a relative increase in EMG activity compared to the CG. The HIVG had a lower masticatory cycle ability while chewing Parafilm M®, Raisins and Peanuts when compared to CG. During rest conditions, the ultrasound images showed a greater average muscular thickness in the right and left temporal region compared to CG. Upon maximal voluntary contraction, an increased average thickness was seen in the temporalis muscles and left sternocleidomastoid muscle when compared to the CG. Conclusion : Based on the results of this research, it can be concluded that individuals with acquired immunodeficiency syndrome showed muscular changes related to the Stomatognathic System, especially concerning EMG activity and muscle thickness.

Clinical Characteristics of Functional Movement Disorders in the Stomatognathic System.
Frontiers in neurology, 2020Co-Authors: Kazuya YoshidaAbstract:Background: Functional (psychogenic) movement disorders often have distinguishable clinical features in the orofacial region. Tonic mandibular deviation accompanying ipsilateral downward and lateral lip pulling is the most common phenotype seen in patients with facial functional movement disorders. However, functional movement disorders in the Stomatognathic System are underrecognized. Objective: This study aimed to evaluate clinical characteristics and phenomenology in patients with functional movement disorders in the Stomatognathic System. Methods: Ten-item inclusion criteria (point range: 0-10) for functional movement disorders in the Stomatognathic System was produced, based on previously established criteria for functional movement disorders and general signs of functional facial dystonia, to determine subject inclusion. The criteria included inconsistency, incongruence, and paroxysm in symptoms; rapid onset; distractibility; suggestibility; static course; spreading to multiple sites; spontaneous remission; and lack of sensory tricks. Fifty-eight patients [42 women (72.4%), 16 men (27.6%); mean age: 46.2 years] scored over 7 points on the criteria and were included in further analyses. Characteristic features, including the pattern and site of abnormal movements, were assessed in clinical examination. Results: Frequent items in the scale were inconsistent symptoms (93.1%), incongruous symptoms (91.4%), spreading to multiple sites (89.7%), paroxysmal symptoms (86.2%), and lack of sensory tricks (81%). Sixty percent of patients exhibited a pattern resembling dystonia. Some patients had a combination of organic and functional disease. Common involuntary movements included jaw deviation (74.1%), jaw closing (50%), lip pulling (34.5%), and tongue movement (31%). A functional dystonia phenotype (unilateral lower lip pulling and jaw deviation) was observed in 26 patients (44.8%). Characteristic features of functional Stomatognathic movement disorders were rapidly repeating mandibular (lateral or tapping) and tongue movements (27.6%), which fluctuated in speed and direction. Conclusion: In 58 patients with functional movement disorders in the Stomatognathic System, the functional dystonia phenotype was observed in 44.8%. Furthermore, 27.6% of patients showed the most characteristic type of functional Stomatognathic movement disorders: very fast repeated jaw and/or lingual movements.

Developmental medicine and child neurology, 2015Co-Authors: Bruno Ferreira, Veridiana Wanshi Arnoni, Selma Siéssere, Marisa Semprini, Gabriel Pádua Da Silva, Edson Donizetti Verri, Camila Rosa Gonçalves, Thaís Cristina Chaves, Simone Cecilio Hallak RegaloAbstract:Aim This study aimed to analyze electromyographic activity, masticatory efficiency, muscle thickness, and bite force of individuals with Duchenne muscular dystrophy (DMD). Method Forty males were selected, divided between the Duchenne group (n=20) and the control group (n=20). They were submitted to electromyography (EMG) analysis (temporalis, masseter and sternocleidomastoid muscles) during the postural control of the jaw, mastication, maximal molar bite force, and ultrasonography analyses. Results The normalizad EMG signals showed that the Duchenne group presented higher averages for masseter and temporal muscles in rest, protrusion, left and right laterality, and fatigue condition when compared to control group (p≤0.05). For masticatory efficiency of cycles, in analysis of non-habitual chewing of flavorless gum (Parafilm M; Pechinery Plastic Packaging, Batavia, IL, USA), and habitual chewing of peanuts and raisins, the Duchenne group presented lower averages when compared to control group (p≤0.05). For the muscle thickness the results showed that there was a lower muscle thickness in Duchenne group for all muscles during the rest and maximal voluntary contraction, except for masseter and sternocleidomastoid in the maximal voluntary contraction. In the maximum molar bite force, the control group presented the highest values for both sides when compared to Duchenne group (p≤0.05). Interpretation We conclude that Stomatognathic System changes occur in carrier DMD.

Journal of Dentistry Oral Disorders and Therapy, 2014Co-Authors: Andre M M Dante, Marcelo Palinkas, Selma Siéssere, Marisa Semprini, Gabriel Pádua Da Silva, Bruno Ferreira, Carla Moreto Santos, Joao B M Lellis, Helio M Tanimoto, Regiane A F LellisAbstract:The purpose of this study was to evaluate the Electromyography (EMG), thickness of the masseter and temporal muscles, maximal bite force in individuals with head and neck cancer treated with radiotherapy. The patterns of the muscle activity were evaluated by means of the EMG recordings of the masseter and temporal muscles; bilaterally during the following clinical conditions: rest, protrusion, right and left lateral excursions and Maximum Habitual Intercuspation (MHI). Muscle thickness was evaluated using ultrasound at rest and in MHI. Maximal bite force in the right and left molar regions of 10 fully dentate individuals with head and neck cancer was evaluated after radiotherapy and compared with a control group. The EMG means showed that at rest, protrusion, and left lateral excursion, there were statistically significant differences (p < 0.05). On evaluation with ultrasound, the muscle thickness values were higher for individuals with head and neck cancer at rest and in MIH, with statistically significant results found only for the right temporal during the MIH. Participants with head and neck cancer treatment were evaluated in the present study showed higher electromyographic activity when compared with the control group for all clinical situations. The treatment used with patients undergoing head and neck cancer increased the electromyographic activity, the muscle thickness, and the bite force when compared to control subjects. The results suggest a muscle dysfunction of the Stomatognathic System in individuals with head and neck cancer treatment evaluated in the present study.

Severity of Sleep Bruxism and its Implications for the Stomatognathic System in Healthy Subjects
Open Access Macedonian Journal of Medical Sciences, 2020Co-Authors: Marcelo Palinkas, Isabela Hallak Regalo, Jaime Eduardo Cecílio Hallak, Natália Yanota Marin, César Bataglion, Edneia Corrêa De Mello, Graziela De Luca Canto, Lígia Maria Napolitano Gonçalves, Takami Hirono Hotta, Selma SiéssereAbstract:BACKGROUND: Sleep bruxism (SB) changes the functionality patterns of the Stomatognathic System. However, its severity can be an aggravating factor in the function of this complex System. AIM: The purpose of the study was to investigate the Stomatognathic System of healthy subjects with different severity of SB, as determined by BiteStrip. METHODS: Thirty-four subjects were divided into two groups: Mild SB (n = 15) and severe SB (n = 19). Electromyograph was used to evaluate the electromyographic activity of the right masseter (RM), left masseter (LM), right temporal (RT), and left temporal (LT) muscles at mandibular rest, right and left laterality, protrusion, and maximum voluntary contraction. Molar bite force was measured by the dynamometer. The data were tabulated and submitted for statistical analysis (p < 0.05). RESULTS: Molar bite force was significantly lower in the severe SB group. There was a significant increase in electromyographic activity in the severe SB group for the mandibular rest tasks (RM, RT, and LT), protrusion (RM, LM, RT, and LT), and right and left laterality in the temporalis muscles. There was a significant decrease in electromyographic activity in the severe SB group in maximum voluntary contraction for the masseter and temporalis muscles. CONCLUSION: Subjects with severe SB demonstrated greater functional impairment of the Stomatognathic System, mainly affecting the electromyographic activity and molar bite force.

The effects of Duchenne muscular dystrophy on the performance of the Stomatognathic System: case–control study
Developmental medicine and child neurology, 2015Co-Authors: Bruno Ferreira, Veridiana Wanshi Arnoni, Selma Siéssere, Marisa Semprini, Gabriel Pádua Da Silva, Edson Donizetti Verri, Camila Rosa Gonçalves, Thaís Cristina Chaves, Simone Cecilio Hallak RegaloAbstract:Aim This study aimed to analyze electromyographic activity, masticatory efficiency, muscle thickness, and bite force of individuals with Duchenne muscular dystrophy (DMD). Method Forty males were selected, divided between the Duchenne group (n=20) and the control group (n=20). They were submitted to electromyography (EMG) analysis (temporalis, masseter and sternocleidomastoid muscles) during the postural control of the jaw, mastication, maximal molar bite force, and ultrasonography analyses. Results The normalizad EMG signals showed that the Duchenne group presented higher averages for masseter and temporal muscles in rest, protrusion, left and right laterality, and fatigue condition when compared to control group (p≤0.05). For masticatory efficiency of cycles, in analysis of non-habitual chewing of flavorless gum (Parafilm M; Pechinery Plastic Packaging, Batavia, IL, USA), and habitual chewing of peanuts and raisins, the Duchenne group presented lower averages when compared to control group (p≤0.05). For the muscle thickness the results showed that there was a lower muscle thickness in Duchenne group for all muscles during the rest and maximal voluntary contraction, except for masseter and sternocleidomastoid in the maximal voluntary contraction. In the maximum molar bite force, the control group presented the highest values for both sides when compared to Duchenne group (p≤0.05). Interpretation We conclude that Stomatognathic System changes occur in carrier DMD.
