Purpose: to evaluate the electromyographic parameters of swallowing different types of clinical stages of idiopathic Parkinson disease on and off. Methods: the study was performed at the Clinic of Neurology, Hospital of the Federal University of Pernambuco. The population of the study were 20 patients with Parkinson disease, divided by Unified Scale for Assessment of Parkinson's disease in three groups: flickering, akinetic-rigid and mixed. The surface electromyography examination was collected on suprahyoid muscles during swallowing and 3 ml water and 10 ml of yoghurt, which was repeated 5 times for each volume and consistency. This protocol was carried out before and after the medication period off and on. Results: it was found that the phase off, akinetic-rigid group had the highest average in parts of swallows and duration of surface electromyography, while the mixed group had the lowest average amplitude. In phase on the three groups tended to improve or maintain the averages of the variables, but there was no significant difference between the clinical types, before or after Levodopa. Conclusion: drug therapy through Levodopa shows no consistent differences in surface electromyography of swallowing the clinical types of Parkinson disease. [ABSTRACT FROM AUTHOR] more...

Purpose: to investigate the relationship of the masticatory preference side in the electrical activity of masseter and temporalis muscles. Methods: the sample was composed by 115 children aged between 7 and 12 years. The acquisition of the electrical activity of the masticatory muscles was recorded during 5 seconds of isometric contraction in maximal intercuspal position. The children were divided into four groups according to masticatory preference observed: Chewing Preferential Right, Left, Bilateral Alternating, and Bilateral Simultaneous. The electromyographicdata were analyzed using the SPSS 17.0 software, and for determination of statistical difference between the electrical activity of the right and left masseter and temporalis muscles was performed by Paired Student t-test (p <0.05). Results: from the total of 115 children, 76 (63.4%) had a preferred side during mastication, whereas 44 (36.7%) children had masticatory right and 32 (26.7%) preferred chewing left. Of the individuals without a preferred side, it was found 25.8% (n = 31) alternating with bilateral chewing and 10.8% (n = 13) with simultaneous bilateral chewing. After comparing the electrical activity of the masseter and temporal, right and left, according to the group chewing, it was found that the average electrical activity of the muscles on the left side showed no statistically significant differences when compared with the average of its peers right side. Conclusion: for the study sample, there was no relationship between the habitual chewing side and electrical activity of the muscles masseter and temporal. [ABSTRACT FROM AUTHOR] more...

Purpose: to compare the electrical activity of masseter and temporal muscles, (anterior fascicle) at rest, in maximum voluntary isometric contraction and chewing, taking the original value analysis (μ v) and Root Mean Square (RMS). Methods: observational and descriptive study. Surface Electromyography was held in the masseter and temporal muscles (anterior portion) bilaterally, in 18 women between 27 and 50 years of age. The assessment was carried out in three situations: at rest, in maximum voluntary isometric contraction and habitual chewing dried vine fruit without seeds, as food. The electromyography used was the BIOPAK, Bioresearch Associates, four-channel, model 800 and bipolar surface electrodes (Bio Trodoon gel). The signal records were obtained in microvolts, and analyzed and compared in the original signal and RMS root mean square. Results: when we compare the electrical activity of masseters and temporal muscles (anterior fascicle), there is no statistically significant differences between the original and RMS values at rest. Both in maximum voluntary isometric contraction and habitual chewing, we find statistically significant higher values to RMS. There was a predominance of electrical activity in muscles masseters when compared to the temporal muscle, anterior fascicle, both chewing and in maximum voluntary isometric contraction. Conclusion: there is a minimum of electrical activity at rest. Both the tooth clenching and mastication of dried vine fruit we find RMS average values greater than original mean values. There has been greater electrical activity of muscles masseters when compared to the temporal muscle, both in maximum voluntary isometric contraction as chewing. [ABSTRACT FROM AUTHOR] more...

Purpose: to study was to analyze the electrical activity of Masseter and Temporalis muscles and the pattern of posture and movement of the head and jaws of children with cerebral palsy (CP). Methods: the sample comprised 32 volunteers with spastic CP and with normal development, with ages ranging from 7 to 13 years of age, characterized based on the Classification of Angle and Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Simultaneously, we evaluated the position and movement of the head and jaw and electrical activity of Temporalis and Masseter muscles by means of kinematic and electromyography. Results: the CP was not associated with the presence of TMD or with the alteration of dental occlusion. In the CP group, there was greater asymmetry of the temporalis muscle (p<0.05), more head extension at maximum mouth opening (p<0.05), greater range of head extension (p<0.01) and greater range of anterior projection of the head (p<0.05). Conclusion: the greater asymmetry in muscle activity, the greater extension and projection of the head during the chewing cycle can be causes of disorders of the oral motor function of children with CP.

Purpose: to verify the existence of an association between the degree of spasticity, the level of motor function and wide topographical classification of CP children with amplitude and time parameters of electromyographic activation of temporalis (AT) and masseter (MA) muscles. Methods: muscle activity during chewing task was evaluated in fifteen children with CP. The clinical instruments used were the Modified Ashworth Scale for spasticity, the Gross Motor Function Classification System (GMFCS) for gross motor function. We analyzed the parameters of muscular symmetry and time of active and inactive period of the masticatory cycle. Results: there was an association between the level of motor function and the symmetry of the MA, between the highest degree of spasticity and decrease in the inactive period and increase in the active period of the masticatory muscles and between the topographical classification and symmetry of the MA and the symmetry of the AT. Conclusion: the symmetry and the time of activation of AT and MA should be considered during therapy of oral motor function of CP children. [ABSTRACT FROM AUTHOR] more...

Purpose: to observe whether a relationship exists between the preference of chewing side, facial anthropometry and electrical activity of masseter muscle in total laryngectomy. Methods: data collection, performed in the Speech Therapy Cancer Hospital of Pernambuco (HCP), with the participation of fifteen volunteers laryngectomized males and mean age of 64 years. We performed measurement of distances between points and anthropometric facial ex ch in hemifaces of volunteers and later executed EMG of the masseter muscles, bilaterally, in his habitual intercuspal (MHI), unilateral right and left chewing and during mastication. Filming took place during mastication to identify the side of the preference side. Results: individuals whose right side is the masticatory predominance showed of the left side of the face to a greater extent (72.37 mm), while those whose prevalence of side left masticatory had higher estensão the side right (68.85 mm). In unilateral chewing right the electrical activity of the right masseter had an average 123.57% , while the left masseter showed an average 84.85% of the activity in relation to MHI (p = 0.016). Conclusion: in laryngectomized anthropometric facial measurements correlate with the preference side chewing and the values of the masseter EMG during mastication. [ABSTRACT FROM AUTHOR] more...

Purpose: to investigate the myofunctional and electromyographic characteristics of obese patients in relation to sex and age group. Method: a convenience sample of 28 obese children and adolescents of both sexes, participants in the group of the Obesity Clinic of Pediatrics, University Hospital of Santa Maria, in the period of January to July 2011. The myofunctional characteristics were performed by experienced speech pathologist through the Assessment Protocol Myofunctional with scores (AMIOFE). Electromyographic evaluation of masseter and temporal muscles was obtained using the Lynx Electromyograph and were held three collections for each of the situations (rest, chewing, swallowing and maximum intercuspation). The EMG data were normalized, expressed as a percentage, using the mean of maximal intercuspation of each muscle studied in the assessments. Results: most of the obese in this research presented myofunctional characteristics within the normal range, not being statistically significant difference when compared by sex and age. Although the average standard of the electrical activity of masseter and temporal muscles during rest, chewing and swallowing obese according to sex and age showed no statistically significant difference, there is an increased activation of the masseter muscles than the temporal. Conclusions: it can be concluded that obese children and adolescents of both sexes have myofunctional characteristics within normal limits and there is an increased activation of the masseter muscles for chewing and swallowing of the temporal muscles.

Purpose: to investigate the influence of the habitual head posture, jaw and hyoid bone position on the supra and infrahyoid muscles activity of the muscles during swallowing of different food textures. Method: an observational, cross-sectional study, with women between 19 and 35 years, without myofunctional swallowing disorders. The craniocervical posture, position of the mandible and hyoid bone were evaluated by cephalometry. The electromyographic activity of the supra and infrahyoid muscles was collected during swallowing water, gelatin and cookie. Results: sample of 16 women, mean age 24.19 ±2.66 years. At rest, there were negative/moderate correlations between the electrical activity of the suprahyoid muscles with NSL/CVT (head position in relation to the cervical vertebrae) and NSL/OPT (head position in relation to the cervical spine) postural variables, and positive/moderate with the CVA angle (position of flexion/extension of the head). During swallowing the cookie, the activity of infrahyoid muscles showed a negative/moderate correlation with NSL/OPT angle. It was found higher electrical activity of the suprahyoid muscles during swallowing of all foods tested, and of the infrahyoid muscles at rest. There was difference on the muscle activity during swallowing of foods with different consistencies, which was higher with cookie compared to water and gelatin. Conclusion: the head hyperextension reflected in lower activity of the suprahyoid muscles at rest and of the infrahyoid muscles during swallowing. The consistency of food influenced the electrical activity of the suprahyoid and infrahyoid muscles, with greater muscle recruitment in swallowing solid food. [ABSTRACT FROM AUTHOR] more...

Purpose: present a protocol for evaluating the electrical activity of the masseter and supra-hyoid in newborn preterm infants during feeding. Method: the information was gathered from papers catalogued in Lilacs and MEDLINE, and printed literature in order to identify protocols used in national and international studies on electromyographic evaluation in infants during feeding, prioritizing the last fifteen years. Information was also collected from protocols used in research with other populations that could be used as a theoretical basis for this study. From the reading and analyzing the found materials, an initial electromyographic evaluation protocol was drawn up and was applied in six newborn preterm infants, to verify its applicability. Results: the literature search and testing in the population led to a protocol composed by sub-definition of muscles evaluated, recommendations for skin preparation, electrode placement, positioning for evaluation, normalization of the signal for the evaluation activities, and suggestions analysis and interpretation of the signal. Conclusion: the study shows the possibility of applying this protocol in the evaluation of muscle electromyography in preterm infants, during feeding. The masseter and supra-hyoid are recommended as a good option for studying the electrical activity of muscles activated during feeding in preterm infants. The protocol also recommended procedures for standardizing the signal for better interpretation of data. [ABSTRACT FROM AUTHOR] more...

Purpose: due to the presence of major masticatory dysfunction in patients with temporomandibular joint (TMJ) ankylosis, this study analyzed mouth opening and EMG activity of masticatory muscles in order to detect changes in these parameters after surgical release of mandible ankylosis. Method: in 7 patients with temporomandibular ankylosis, between 7 and 30 years (median = 9 years), the distance was measured as interincisal maximum active (DIMA) and we recorded the electromyographic activity (EMG) of masseter and temporal muscles during voluntary isometric contraction (VIC) and chewing, comparing the data before and after surgery using the Wilcoxon test. Results: higher values were observed for DIMA after surgery (p=0.0277), the asymmetry index showed no difference between the two evaluated periods for both studied muscles, the values of the EMG during VIC decreased after surgery for the right (p=0.0179) and left (p=0.0179) masseter but not for the temporal muscle, there were no changes in EMG values for the studied muscles during mastication. Conclusion: the surgical release of TMJ ankylosis resulted in an increase of mouth opening and decreased amplitude of action potentials generated during maximum isometric voluntary contraction of the masseter muscle on both sides, this did not change the asymmetry index of the masseter and temporal as well as the electromyographic activity of the temporal muscle bilaterally during isometric contraction and masseter and temporal muscles during mastication.

Purpose: to verify the possibility of swallowing evaluation in subjects with and without swallowing disorders by the analysis of electromyographic (EMG) traces, search for specific characteristics and association with clinical examination and electromyography. Method: 39 subjects were divided into two groups: research (GP) 25 subjects with swallowing disorders and (CG) 14 without these disorders. Equipment Miotool 200/400 USB, 4 channels, with electrodes bilaterally on the submental region. Swallowing of saliva and of 5ml of water was registered. The EMG records were reviewed by three judges, after provided the EMG traces. The records were classified into normal and abnormal (single peak, more than one peak, not defined peak, changes in the onset/offset). Test of equality of two proportions was used. Results: for both groups it was obtained a large number of records with unexpected swallows. The results for GP showed the highest percentage of altered swallowing of saliva records, but no statistical differences between groups was found. GC presented various types of swallowing records of saliva without significant prevalence; GP presented predominance of "more than one peak". In swallowing of water, GC showed predominance of "single peak" and a lower incidence of "more than one peak" and GP showed predominance of "single peak" and lower incidence of "not defined peak". Conclusion: analysis of EMG traces didn't show specific characteristics and differences for groups, not reflecting patterns that could characterize the records in subjects with and without clinical swallowing. No correlation between clinical and EMG of swallowing was possible. [ABSTRACT FROM AUTHOR] more...

The chewing, a complex action controlled by the central nervous system, is one of the most important functions of the Stomatognathic System. During this action, the electrical activity of the masticatory muscles may be quantified using a surface electromyography. In order to systematically review the literature, on the methods and foods used in EMGS masseter muscle during mastication, we carried out a search in the databases SciELO, Brazil, Lilacs and Medline / Pubmed, from September to October 2009. We included population-based studies and excluded review studies without clear methodological definition and studies with children, adolescents and elderly. About 657 articles were found at the intersection of the following descriptors and their corresponding in English: chewing and masseter and electromyography, which 12 of them selected. It was found that the methods involved in the execution of surface electromyography of the masseter muscle during mastication, vary according to each author, and there is no standard for a specific food in order to perform the examination.

MEDICAL equipment software - Abstract
Purpose: to describe the construction phases of EMG BioanalyzerBR (version 1.0) and demonstrate its applicability in analyzing parameters provided by surface electromyography (EMG). Method: it is a descriptive analysis software developed in order to analyze the parameters obtained in surface electromyography of muscles involved in swallowing. This software was written in a development environment used by worldwide researchers, with easy accessibility and programming: Scilab. Results: this tool has proved effective for analyzing transferring short data records, having on average 10 seconds duration, but for with longest periods above 20s there were some failures that did not harm the calculation after a few tries. Conclusion: despite the difficulties, EMG BioanalyzerBR fostered the development of channel-by-channel markings and how many marks were needed simultaneously, and thus the tabulation of data became faster and with reduced margin as for human error, but needing improvements for version 2.0.

Background: normal surface electromyography (sEMG) of muscles involved in swallowing. Purpose: to investigate if the literature indicates normal parameters for duration, amplitude and characteristics of the electromyograms of the muscles involved in swallowing (orbicularis oris, masseter, muscles of the suprahyoid muscles and the infra-hyoid region covered by the platysma muscle). Conclusion: the search resulted in 33 references, of which only five were within the inclusion criteria. Only one reference was classified with good level of quality by the Jadad scale with modifications. The selected articles cannot point reliable reference values mainly for EMG amplitude and morphology, because they used a inappropriate sampling rate for the EMG recordings that maximizes the achievement of distorted data for the muscle activity. Literature suggests the normalization of techniques for the electromyographic signal due to the variability between and among subjects. [ABSTRACT FROM AUTHOR] more...

Purpose: to check, through an electromyographic evaluation, the electrical activity pattern of the orbicular oral, masseter and temporal muscles on nasal breathers, obstructive and vicious oral breathers in order to compare them. Methods: 59 children, 15 nasal breathers (NB); 23 vicious oral breathers (VOB) and 21 obstructive oral breathers (OOB) were studied. All were submitted to an otorhinolaringological and speech-language patology evaluation and to an electromyographic exam in rest, masticatoric and labial isometries. We developed a Kruskal-Wallis variance analysis in order to make a comparison between the groups and the two-by-two groups and the Wilcoxon's test in order to compare between the muscles (p<0,05). Results: after comparing the three groups, there were no relevant difference in the studied muscles, except for the right masseter muscle while resting, when the VOB and NB were compared; and to the lower orbicular muscle while resting and left temporal muscle in the masticatoric isometry, when NB and OOB were compared. In the comparison between VOB and OOB, any muscle has showed a relevant difference. The lower orbicular muscle was more active than the upper orbicular muscle while resting and on labial isometry, mainly in VOB and OOB. The relation of the muscles on the opposed sides of face in the masticatoric isometry revealed asymmetry. The temporal muscle demonstrated being more active than the masseters while resting and in masticatoric isometry. Conclusion: the breathing mode did not modify the behavior of the evaluated muscles when comparing the groups; oral breathing etiology did not change the electrical activity of the evaluated muscles when comparing VOB and OOB.

Purpose: to evaluate by the surface electromyography the behavior of the sternocleidomastoid and cervical paraspinalis muscles, bilaterally in patients who use esofagic and artificial larynx as alternative to talk and to determine if these conditions modify the cervical muscles behavior. Methods: ten volunteers were evaluated (two women, eight men), with average age: 49. 7 years, with total laryngectomy, average time of postoperative: 2.6 years, with neck movements limitation, divided in two groups: group 1 with five volunteers (artificial larynx); group 2 with five volunteers (esofagic voice); and group 3 control (seven volunteers). Results: there was no significant difference in the muscular activation pattern during phonation in individuals with esofagic voice and the artificial larynx compared to the control group, however, in the rest condition, there was a significant difference comparing the average values of Root Mean Square (RMS) of groups 1 and 2 with group 3, for the right sternocleidomastoid muscle and the right cervical paraspinalis muscles. Conclusion: the vocal option did not interfere on the muscular activation pattern during the phonation, as well as there was no difference in the muscular activation pattern comparing the experimental groups with the control group.

Purpose: to study the surface electromyographic activity of frontal, orbicular occuli, orbicular oris and zigomatycs muscles in normal subjects and in peripheral facial paralysis patients. Methods: six volunteers with no facial paralysis history as well as six peripheral facial paralysis patients were evaluated with electromyography using superficial electrodes. Maximum effort muscle activity and symmetry index were measured for the voluntary movements such as: raising eyebrows, eyes closing, smiling, puckering lips. Results: it was found out that in normal subjects the muscle activity values were similar between the two sides of the face, showing that the facial nerve integrity is fundamental to the balance of facial mimics. In facial paralysis patients, the mean electromyographic values for both sides of the face were significantly different (evidencing the lack of facial nerve information to the muscles). Conclusion: the electromyographic results showed a statistically significant difference between the two sides of the face in the normal subjects and in facial paralysis patients.

Methods: 16 subjects aged 6:8 - 10:10 and divided on two groups participated in this study, one with mouth and another one with nose breathers. Both groups were submitted to clinical and surface electromyography evaluation. The speech-language evaluation contemplated the exam of the structures and functions of the stomatognathic system. The electromyography evaluation consisted of the captivation of the electrical activity at the orbicularis oris muscles, and lower and upper lips, during isometry and swallowing situations. In the clinical results were considered only the swallowing variables. Therefore, our study could observe the presence of labial and mentalis action and tongue projection, that were analyzed in a descriptive form. The statistical analysis of the electromyography results was done through the t test in order to compare the groups. The statistical considered significance was 5% (p<0.05). Results: in the clinical evaluation it was verified that any of the nose breathers showed atypical swallowing characteristics while 7 (87.5%) of the mouth breathers showed labial action, 6 (75%) showed mentalis action and 6 (75%) showed tongue projection. In the electromyography evaluation, a higher muscular activity was verified, in the mouth breathers, when comparing to the nose breathers, in both lips, with a statistical significance. Conclusions: in this study it was verified that mouth breathers showed significant alterations in the swallowing functions when compared to the nose breathers that were observed through a clinical examination and electromyography evaluation.

Purpose: to compare Suprahyoid musculature's electric activity during swallowing in subjects with dissimilar morphological and dental patterns. Methods: surface Electromyography's records were taken from 32 healthy volunteers who do not have Temporomandibular Dysfunction, subdivided into two groups, Angle's 16 Class I subjects and 16 Class III subjects, males and females, aging from 18 to 25-year old. Results: the values to Root Mens Square (p< 0.05): original Class I (15.238) e Class III (32.550); normalized by maximum peak Class I (29.765) e Class III (42.094); normalized by medium Class I (29.332) e Class III (42.327). Cycle's active period (p<0.05) Class I (29.7648) e Class III (42.0937); maximum activity instance (p>0.05) Class I (47.6485) e Class III (47.9437). Conclusion: class I subjects showed a smaller average amplitude, with increase and decrease of synchronized and balanced electric activity. Class III subjects showed a larger average amplitude and a larger desynchronized and unbalanced period during deglutition. [ABSTRACT FROM AUTHOR] more...

Purpose: to investigate the masticatory preference and the behavior of masticatory muscles, in children between6 to 9-year old, with posterior crossbite. Methods: 30 children were selected from the Orthodontical service of a public university. After consenting to take part in the study, there was an interview with the children and the parent, in order to investigate temporomandibular disorders; masticatory was analyzed through video recording and electromyographic (EMG) evaluation of the masseter and anterior temporal, during the solicited mastication, on right and left, using chewing gum. Results: there was a significant difference in the EMG activity of the masseter and temporal between work and balance sides, however there was no statistical differences in the comparison between crossbite side and no crossbite side, but neither between preference side and non the preference side. Conclusion: in the studied population there was no functional muscular asymmetry established. [ABSTRACT FROM AUTHOR] more...

Background: electromyography and therapeutic behavior. Procedures: this study was carried out with a woman, 45year old, after 4 months from being submitted to fronto-temporal craniotomy originated an aneurysm. The right anterior temporal muscle was removed from its insertion. After the surgery, the patient had dysfunction in temporal muscle and in temporo-mandibular joint, with reduction of the opening of mouth, pain while speaking and eating. Electromyography was used to quantitatively record the electrical activity of the temporal and masseter muscles in the initial evaluation and during the therapeutic process. Records were made at rest position, maximum occlusion and chew. They did miofuncional therapy throughout the process. Results: examination data showed a significant increase in the electrical activity of the right anterior temporal muscle and a reduction in the activity of the left anterior temporal muscle. The initial Record showed a lower electrical activity on the right side compared to the left. With the miofunctional exercises there was a more effective participation of the right anterior temporal muscle, greater openness of mouth, without pain, making easier chewing and speech tasks, harmonizing the stomatognathic system. Conclusion: comparative records concerning electromyography in different stages of the therapeutic process helped and directed the best therapy, achieving a balance concerning the functions of breathing, sucking, chewing, swallowing and speech related to the stomatognathic system, considering the limitations of the case.

Purpose: to investigate differences between electromyographic samples of right and left suprahyoid muscles during deglutition of thickened liquids and liquid consistencies by elderly people with Parkinson disease and elderly people without any neurological disease. Methods: 30 subjects, from both genders, took part in this study. Fifteen were elderly without neurological disease whereas the others showed Parkinson disease. All of them were submitted to a clinical evaluation protocol and surface electromyography. Results: significant amplitude difference was found between subjects (f=14.4 and p=0.000) and between sides (t=4,4 and p=0.0037). As for muscular contraction time, the differences were just significant between the consistencies (f=8.2 and p=0.005). Conclusion: the electromyographic amplitude was shorter for subjects with Parkinson disease and this amplitude was higher in both groups at the right side. The duration of the muscular contraction did not display significant difference between the subjects with Parkinson disease and elderly without neurological disease. This duration was shorter during the deglutition of liquid consistencies. [ABSTRACT FROM AUTHOR] more...
