RESUMO

Health promotion and disease prevention link intricately with lifestyle habits such as a healthy diet, physical activity, and good sleep quality. Temporomandibular joint (TMJ) dysfunction and associated disorders can take away sleep and well-being depending on the form and intensity that affect the individual. A multidisciplinary effort has contributed to significant health advances, improving clinical outcomes concerning TMJ dysfunction. This report presents the case of a 37-year-old Caucasian female physical educator with a good healthy diet with complaints of tooth tightening, constant TMJ and neck pain, and tinnitus. The patient was treated with inferior occlusal splint placement and selective occlusal adjustments based on neuro-occlusal rehabilitation. The patient reported relief of pain symptoms with occlusal and body balance, discontinued analgesic medication, and maintained the occlusal splint to practice sports and sleep due to the perception of improved physical performance and sleep, and quality of life. Based on this report, it is necessary to analyze the causes and define the effects of different disorders to establish their diagnosis and treatment and changing patterns to reestablish functional balance.

RESUMO

OBJECTIVES: Obstructive sleep apnea is an inflammatory, chronic, and evolutive disease often needing adequate treatment and follow-up. The oral appliance (OA) is an accepted alternative therapy for obstructive sleep apnea (OSA) control. Due to greater adherence, OA with mandibular advancement (OAm) is being recommended treatment for patients who refuse or do not tolerate continuous positive airway pressure. The mode of action of OAm is to promote the advancement of the mandible or tongue with a subsequent increase in the tone of the pharyngeal muscles and the permeability of the upper airway, but most OAm use conventional models as reference, analogic, or digital, dissociating dental arches of the skull structures. MATERIALS AND METHODS: A retrospective longitudinal study of 33 OSA patient treated with a different OAm, that use Camper plane as reference with skull structures for dental arches disocclusion, where polysomnographic, cephalometric measures, and subjective data from questionnaires pre- and post-treatment were assessed and correlated. Descriptive analysis, correlated Chi-square tests, and basic statistics were used. Generalized linear mixed model for repeated measure and post hoc Tukey-Kramer test compares the variables pre- and post-treatment. Shapiro-Wilk test and Pearson's correlation coefficients were used. All statistical tests were set in 5% level of significance. RESULTS: Regarding polysomnography data, there was a significant association between apnea hypopnea index (AHI) with oxygen saturation, arousal index (AI) and the maximum heartbeats, and sleep improvement and health risk reduction. Additionally, from cephalometric data, it was found a significant association between the tongue posture with the soft palate, hioyd-C3 and, lower and posterior airway. When both parameters are correlated, there are a significant dependent association with hyoid bone position with AHI and AI. The limitation of this study was the two-dimensional image used without provide volumetric measurements, but this limitation was reduced with the follow-up polysomnography parameters. CONCLUSION: In this pilot study, DIORS OAm as an uniquely designed device using Camper plane as a reference for disocclusion was effective in the control of OSA.

RESUMO

SUMMARY: Human identification involving mutilation, advanced decomposition, and skeletonized materials is a challenge for professionals in forensic medicine and dentistry. This study was aimed at a morphometric analysis of the mastoid and bimastoid triangles to determine sex in a Brazilian population. The sample included 80 human skulls (34 females and 46 males; age: 18 to 60 years) from individuals with death certificates. Linear measurements (mm) of the mastoid process - right (n=3) and left (n=3) - and the opisthion- bimastoid (n=3) triangles were taken (digital caliper) by two previously trained researchers. Three cranial points - asterion, porion and process - were determined for the right and left mastoid triangle and three others - (1) opisthion and (2) right and (3) left mastoid - for the bimastoid triangle. Heron's formula was used to calculate the area of the triangles assessed. Data were submitted to the Shapiro- Wilk normality test, followed by the unpaired Student's t test or the Mann-Whitney U test, depending on the data distribution verified in the normality test (GraphPad Prism 5.01; p<0.05). The ROC curve was used to measure the accuracy of the variables toward sex determination. The opisthion-bimastoid triangle showed high accuracy and significant differences in all the variables assessed and thus was considered a potential element for sex determination in the Brazilian population assessed.


RESUMEN: La identificación humana que comprende la mutilación, descomposición avanzada y materiales esqueletizados, es un desafío para los profesionales de la medicina forense y de la odontología. Este estudio tuvo como objetivo un análisis morfométrico de los triángulos mastoideo y bimastoideo para determinar el sexo en una población brasileña. La muestra incluyó 80 cráneos humanos (34 mujeres y 46 hombres; edad: 18 a 60 años) de sujetos con certificado de defunción. Se tomaron las medidas lineales (mm) del proceso mastoides - derecha (n = 3) e izquierda (n = 3) - y los triángulos opistion-bimastoide (n = 3) (caliper digital) por dos investigadores previamente entrenados. Se determinaron tres puntos craneales - asterion, porion y proceso mastoides - para el triángulo mastoideo derecho e izquierdo y otros tres - (1) opistion y (2) proceso mastoides derecho e izquierdo - para el triángulo bimastoideo. Se utilizó la fórmula de Heron para calcular el área de los triángulos evaluados. Los datos se analizaron con la prueba de normalidad de Shapiro-Wilk, seguida de la prueba t de Student para datos no apareados o la prueba U de Mann-Whitney, según la distribución de datos verificada en la prueba de normalidad (GraphPad Prism 5.01; p <0.05). La curva ROC se utilizó para medir la precisión de las variables hacia la determinación del sexo. El triángulo opistion-bimastoide mostró una alta precisión y diferencias significativas en todas las variables evaluadas, por lo que se consideró un elemento probable para la determinación del sexo en la población brasileña evaluada.

RESUMO

OBJETIVES: The Pilates method, developed by Joseph Pilates (1886-1967), has been widely used to improve trunk stability, muscle flexibility and strength, physical fitness, and body awareness. To measure the electromyography of four trunk muscles during three Pilates exercises carried out of the wunda chair. DESING: cross-section study. METHODS: Sixteen women participated in this study with a height and body weight of 1.64 ± 0.04 m and 58.7 ± 7.4 kg, respectively, and a mean age of 27.6 ± 3.7 years. Rectus abdominis (RA), internal oblique (IO), longissimus (LO), and multifidus (MU) muscles was evaluated by electromyographic (EMG) tests activity during three Pilates exercises: going up front (GF), mountain climb (MC), and swan (SW). EMG was normalized and expressed in the time domain, by the RMS. RESULTS: The highest EMG values concerning the four muscles were observed for the MC exercise, followed by GF and SW (ANOVA: p = 0.0001, p = 0.04, p = 0.0002, and p = 0.0013, respectively). Our results show that the three Pilates exercises could recruit all the muscles, with a moderate activity intensity. The ANOVA; p < 0.05 showed significant difference between the muscles, concerning SW (p = 0.0002). CONCLUSION: Our results show that the three Pilates exercises could recruit all the muscles, with a moderate activity intensity.

RESUMO

INTRODUCTION: The most prescribed treatment option for Obstructive Sleep Apnea (OSA) is CPAP; however, its adherence is limited. Oral Appliance therapy (OAT) is frequently an option or even an adjuvant, being the mandibular advancement Oral Appliance (OAm) the most used prescription. It modifies the upper airway, improving the airway patency. OAm construction is based on the occlusal plane to disocclusion. In this study, the DIORS® appliance was used, a singular OAm, based on Neuro-Occlusal Rehabilitation concepts, that uses Camper's plane as a disocclusion reference, in order to achieve neuromuscular balance and functional stability. OBJECTIVE: This study primarily aimed to assess the DIORS® effectiveness in relation to clinical and polysomnographic outcomes. It was also evaluated if the use of DIORS® is as effective as titrated CPAP to treat CPAP non-adherent patients. METHODS: Twenty patients were included in this study. Objective and subjective clinical data were assessed at a sleep laboratory using all-night polysomnography, and Epworth Sleepiness Scale (ESS), taken at three moments: Baseline, CPAP titration, and using DIORS®. Analysis of respiratory parameters as apnea/hypopnea index (AHI), oxyhemoglobin saturation levels, the arousal index and daytime sleepiness were taken as criteria for a successful OAT. RESULTS: Respiratory and arousal parameters improved in both therapies, while DIORS® promoted a better ESS. CONCLUSION: Results from the present work support that DIORS® is a viable and effective adjuvant therapy for patients with moderate to severe OSA non-adherent to CPAP.

RESUMO Introdução: A opção mais indicada para tratamento da apneia obstrutiva do sono (AOS) é o CPAP; contudo, a aderência é limitada. A Terapia com Aparelho Oral (TAO) é, frequentemente, uma opção, ou mesmo um adjuvante. A prescrição mais utilizada é o Aparelho Oral de avanço mandibular (AOm). O AOm modifica a via aérea superior, melhorando a patência do espaço aéreo. A construção do AOm se baseia no plano de oclusão para desoclusão. No presente estudo, usamos o DIORS®, um AOm diferente, baseado nos conceitos da Reabilitação Neuro-Oclusal (RNO), que utiliza o Plano de Camper como referência da desoclusão para alcançar o equilíbrio neuromuscular e estabilidade funcional. Objetivo: O presente estudo teve como objetivo principal abordar a eficácia do DIORS®, considerando-se os resultados clínicos e polissonográficos. Adicionalmente, foi avaliado, também, se o uso desse AOm é tão eficaz quanto a titulação do CPAP para tratar pacientes com AOS não aderentes ao CPAP. Métodos: Vinte pacientes foram incluídos neste estudo. Dados clínicos objetivos e subjetivos foram avaliados em um laboratório de sono usando polissonografia de noite inteira e a Escala de Sonolência de Epworth (ESE) observando-se três momentos: inicial, titulação do CPAP e usando o DIORS®. Os critérios de sucesso da TAO foram assumidos pela análise dos parâmetros respiratórios como Índice de Apneia e Hipopneia (IAH) e níveis de saturação de oxi-hemoglobina, o índice de despertar e a sonolência diurna. Resultados: Em ambas as terapias, os parâmetros respiratórios e de despertares melhoraram. Adicionalmente, uma melhora na ESE foi alcançada com o DIORS®. Conclusão: Os resultados do presente trabalho apoiam que o DIORS® é uma terapia adjuvante viável e bastante eficaz para pacientes com AOS moderada a grave não aderentes ao CPAP.

RESUMO

PURPOSE: To compare the impact of isokinetic exercise (tongue suction on the palate) in the cervical region of Class I and Class II / 2nd Division participants, considering the average and the symmetry of Root Means Square (RMS) of suprahyoid and suboccipital muscles and cervical sensory reports. METHOD: 11 participants Class I and 19 Class II / 2nd Division, both genders, mean age 33.4 ± 14.1 years. For the analysis of RMS average and symmetry, electromyography was performed in the suboccipital and suprahyoid muscles, bilaterally, at rest and suction of water in the initial, intermediate and final phases. The cervical sensation was evaluated qualitatively during the exercises. RESULTS: the mean RMS did not differ between Classes (p=0.7), but showed an increase in the intermediate phase in the suboccipital musculature (p=0.0001) and decrease in the suprahyoid musculature. In symmetry, the suprahyoid musculature showed a significant difference between classes (p=0.0001) during the intermediate phase. In the Class I participant the symmetry was reestablished in the final phase, a fact that did not occur in Class II / 2nd Division. Regarding the cervical sensation, only the Class II / 2nd Division had expressive complaints. CONCLUSION: The Isokinetic suctioning exercise of the tongue against the palate, had an expressive repercussion with reports of discomfort and neck pain in the Class II / 2nd Division participants. On average RMS, there was no difference between the classes, but in the intermediate phase, the suboccipital muscles showed a significant increase in the activity. Symmetry in the suprahyoid musculature had a significant difference between the classes and asymmetry in the intermediate phase.

RESUMO

Silva, FHO, Arantes, FJ, Gregorio, FC, Santos, FRA, Fidale, TM, Bérzin, F, Bigaton, DR, and Lizardo, FB. Comparison of the electromyographic activity of the trunk and rectus femoris muscles during traditional crunch and exercise using the 5-minute Shaper device. J Strength Cond Res 34(1): 1-10, 2020-Different training devices are available to trigger greater activation of the abdominal muscles compared with that achieved during traditional abdominal exercises. This study aimed to compare the electromyographic (EMG) activity of the upper and lower rectus abdominis, external oblique abdominis, erector spinae, and rectus femoris (RF) muscles during traditional crunch and exercise using the 5-minute Shaper device. A convenience sample of 15 healthy men (mean ± SD; age: 23.65 ± 4.49 years, body fat percentage: 14.26 ± 3.56%) was selected. All men regularly participated in physical activity. Electromyographic data were collected for 5 repetitions of each abdominal exercise (traditional crunch and exercise using the 5-minute Shaper device at beginner, intermediate, advanced, and extreme levels) in a randomized and counterbalanced manner. Data were collected using simple differential surface electrodes and analyzed using repeated-measures analysis of variance (p < 0.05). Electromyographic signals were quantified using a root-mean-square analysis and normalized using the maximum voluntary isometric contraction. Traditional crunch produced greater or similar EMG activity in the abdominal muscles and minimized RF activity compared to the 5-minute Shaper device, hence, traditional crunch is preferred for training, especially for individuals with weak abdominal musculature and lower back problems. Therefore, the use of the 5-minute Shaper device may be questioned when it is intended to intensify the activity of the abdominal muscles; however, this apparatus may be used if greater variations in training are desired, depending on individual preferences.

RESUMO

BACKGROUND: The co-contraction of the core muscles has been reported as the key mechanism towards spinal stability. Classic Pilates exercises aimed at these muscles are known to improve the stability and strength of the trunk without damaging the deep structures of the spine. OBJECTIVE: To evaluate the co-contraction of the mobilizing (rectus abdominis; longissimus) and stabilizing (multifidus; internal oblique) trunk muscles during Pilates exercises - going up front, mountain climber, and swan. METHODS: Sixteen women, all Pilates practitioners, participated in the study. The stabilizing and mobilizing muscles of the trunk (right side) were submitted to electromyography to calculate the percentage of co-contraction during the exercises. One-way repeated measures analysis of variance (ANOVA) was used to verify the difference in %COCON between stabilizers and mobilizers among the three exercises. The post-hoc Bonferroni test (P< 0.01) was applied when necessary. The paired t-test (P< 0.01) was used to verify the difference in %COCON between stabilizers and mobilizers separately for each exercise. RESULTS: The co-contraction values of the stabilizers were higher than those of the mobilizers for all exercises. The going up front (stabilizers) and the swan (mobilizers) exercises showed the highest %COCON values. CONCLUSIONS: The Pilates method is effective for either rehabilitating pathologies or training the trunk muscles in healthy individuals and athletes.

RESUMO

RESUMO Objetivo: Comparar o impacto do exercício isocinético "sucção da língua contra o palato" na região cervical em participantes Classe I e Classe II/2.ª Divisão, considerando a média e a simetria do Root Means Square (RMS) dos músculos supra-hióideos e suboccipitais, e relatos sensoriais cervicais. Método: Onze participantes Classe I e 19 Classe II/2.ª Divisão, ambos os gêneros, média de idade 33,4 ±14,1 anos. Para análise da média do RMS e da simetria, realizou-se eletromiografia dos músculos suboccipitais e supra-hióideos, bilateralmente, no repouso e na sucção de água nas fases inicial, intermediária e final. A sensação cervical foi avaliada qualitativamente durante os exercícios. Resultados: A média do RMS não apresentou diferença entre Classes (p=0,7), mas revelou, na fase intermediária, elevação na musculatura suboccipital (p=0,0001) e diminuição na musculatura supra-hióidea. Na simetria, a musculatura supra-hióidea mostrou diferença significativa entre classes (p=0,0001) durante a fase intermediária. No participante Classe I, foi restabelecida a simetria na fase final, fato que não ocorreu na Classe II/2.ª Divisão. Em relação à sensação cervical, somente os Classe II/2.ª Divisão apresentaram queixas expressivas. Conclusão: O exercício isocinético de sucção da língua contra o palato repercutiu de forma expressiva com relatos de desconforto e dor cervical nos participantes Classe II/2.ª Divisão. Na média do RMS, não houve diferença entre as classes, mas, na fase intermediária, a musculatura suboccipital apresentou elevação de atividade significativa. A simetria na musculatura supra-hióidea teve diferença significativa entre as classes e assimetria na fase intermediária.

RESUMO

OBJECTIVE: To evaluate the electromyographic (EMG) activity of the rectus abdominis (RA) and internal oblique (IO) muscles during Pilates exercise on different trunk supporting bases. METHODS: Sixteen female Pilates practitioners participated in the study. EMG of the RA and OI muscles was evaluated during the double leg stretch (DLS) exercise on three different supporting bases - mat, long box, and short box. Trunk stability varies according to the size and type of the base. To normalize the data, the RMS value (EMG) obtained during the DLS exercise was divided by the RMS value from the torque test - the maximal voluntary isometric contraction (MVIC) - and multiplied by 100 (%MVIC). One-way repeated-measured analysis of variance (ANOVA) and Bonferroni tests were used to compare data concerning the supporting bases and Student t-test regarding the muscles (p < 0.05). RESULTS: The comparison among the bases involving each muscle - RA or IO (p < 0.05) - showed significant difference (%MVIC) between the mat and the short box. No significant difference was observed between the muscles concerning the exercise on the mat (p = 0.9266), on the long box (p = 0.5113) and on the short box (p = 0.2972). CONCLUSION: The short box increased the activity of the rectus abdominis and internal oblique muscles during exercise. The DLS exercise was able to challenge the stability of the trunk and thus recruit its stabilizer and mobilizer muscles at the same intensity.

RESUMO

A principal finalidade do método Pilates é desenvolver uma automação dos músculos do core. Sendo assim, o objetivo deste estudo foi analisar a razão eletromiográfica dos músculos Oblíquo Interno (OI) e Reto do Abdômen (RA) localizados na parte anterior do tronco, a razão eletromiográfica dos músculos Multífido (MU) e Longuíssimo do Tórax (LO) localizados na parte posterior do tronco, e também a razão ântero-posterior (A/P=RA+IO/LO+MU) desses músculos durante o exercício swan do método Pilates, realizado sobre a Wunda Chair. Na comparação entre as três razões, foram encontradas diferenças estatísticas (p = 0,0103), apenas entre as razões ântero-posterior (A/P), e entre a razão dos músculos localizados na parte posterior do tronco (MU/LO). Os resultados demonstraram que houve um predomínio na atividade eletromiográfica dos músculos da região posterior em relação aos músculos da região anterior do tronco e que os músculos estabilizadores apresentaram maior atividade eletromiográfica em comparação com os músculos globais ou mobilizadores. O exercício swan pode ser utilizado como forma de treinamento para a musculatura do tronco, e como consequência gerar maior estabilidade a coluna vertebral, pois o exercício prioriza a diminuição da carga sobre a coluna vertebral. (AU)


The main purpose of the Pilates method is to develop an automation of core muscles. Thus, the aim of this study was to analyze the electromyographic ratio of the Internal Oblique (IO) and Rectus Abdominis (RA) muscles located in the anterior part of the trunk, the electromyographic ratio of the Multifidus (MU) and Longissimus Thoracis (LO) muscles, located in the posterior part of the trunk, and also the ratio antero- posterior (A/P=RA+IO/LO+MU) of these muscles during the swan exercise of the Pilates, performed on the Wunda Chair. In the comparison between the three ratios, statistical differences (p = 0.0013) were found only between the antero-posterior (A/P) ratios and the ratio of the muscles located in the posterior part of the trunk (MU/LO). The results showed a predominance of the electromyographic activity in the muscles of the posterior region in relation to the muscles of the anterior region of the trunk. The stabilizing muscles presented greater electromyographic activity in comparison to the global or mobilizing muscles. The swan can be used as training for the trunk muscles, and therefore generates greater stability of the spine, since exercise prioritizes the decrease of the load on the spine. (AU)

RESUMO

Physical training has frequently been indicated for ballet dancers to strengthen their trunk muscles, improve their performance, and avoid injuries. The current authors hypothesized that these dancers could benefit from Pilates exercises to stabilize their trunk muscles and improve joint stability and neuromuscular efficiency (NME). Our study aimed at evaluating the NME and isometric strength of the internal oblique (IO) and multifidus (MU) muscles in a healthy 24-year-old classical ballerina before and after an 8-week Pilates exercise intervention. The muscles were tested with electromyography (EMG) and a dynamometer, and the resulting torque and EMG values were used to calculate the NME. Based on the results, the Pilates exercises could improve the NME of the muscles tested, since the torque increased and the EMG activity decreased after the intervention.

RESUMO

BACKGROUND: Pilates exercises help stabilize the vertebral segments by recruiting the abdominal and spinal muscles. Pilates training may increase joint stability and improve neuromuscular efficiency (NME). OBJECTIVE: This study aimed to evaluate NME of the multifidus (MU) muscle through electromyography (EMG) analysis and torque test, applied to practitioners and non-practitioners of Pilates. METHODS: Participants included thirty women: Pilates practitioners (n = 15) and non-practitioners (n = 15). They were tested for trunk extension. Their right and left MU muscles were submitted to EMG to estimate NME. Results concerning torque, EMG, and NME from all participants were compared. RESULTS: Statistical analysis concerning isometric torque peak (p = 0.0275) and NME (p = 0.0062) showed significant difference (Student t test; p < 0.05) between practitioners and control. No significant difference (p = 0.3387) in EMG was observed. CONCLUSION: Our results suggest Pilates exercises is effective in training spinal muscles to improve NME in women.

RESUMO

ABSTRACT Purpose: to compare the behavior of perioral muscles in nasal, oral and oronasal respirators. Methods: a sample consisting of three distinct groups, equally subdivided into Nasal, Oral and Oronasal Respirators. The behavior of the orbicular muscle of the mouth (upper part) and mentual one was measured by surface electromyography at rest, swallowing and labial isometry. Results: in all situations investigated, the orbicular muscle of the mouth (upper part) and mental muscle showed no significant difference in relation to Root Means Square, that is, average electrical activity between Oral and Oronasal Respirators. The data showed a significant difference in In Nasal Respirators, as compared to the other groups. Conclusion: similarity was seen in the comparison of perioral muscles behavior between oral and oronasal respirators, however, a significant difference in relation to nasal respirators.


RESUMO Objetivo: comparar o comportamento dos músculos periorais em respiradores nasais, orais e oronasais. Métodos: amostra constituída por três grupos distintos, igualmente subdivididos em Respiradores Orais, Nasais e Oronasais. Com faixa etária entre 6 e 12 anos de ambos gêneros. O comportamento dos músculos orbicular da boca (parte superior) e mentual foi mensurado por meio da eletromiografia de superfície no repouso, deglutição e isometria labial. Resultados: em todas as situações investigadas o músculo orbicular da boca (parte superior) e músculo mentual não revelaram diferença significante em relação ao Root Means Square, ou seja, atividade elétrica média entre os Respiradores Orais e Oronasais. Já nos Respiradores Nasais os dados comprovaram diferença significante em relação aos demais grupos. Conclusão: na comparação do comportamento dos músculos periorais entre os respiradores orais e oronasais houve similaridade mas diferença muito significante em relação aos respiradores nasais.

RESUMO

Ankle sprains are commonly related to sporty activities and often associated with decreases in sensorimotor control, including proprioception, muscle strength and balance. The use of unstable surfaces in the fields of rehabilitation and general fitness has been shown to be effective in increasing the sensory efficiency of soft tissues that stabilize the knee and ankle as well as improving the agonist-antagonist co-contraction. The aim of this study was to analyze the EMG activity of the ankle muscles ­ the tibialis anterior (TA), peroneus longus (PL) and medial head of the gastrocnemius (GM) during proprioceptive exercises using the BOSU compared to other devices traditionally used (balance platform, trampoline and proprioceptive disk). Eleven male volunteers were recruited and data collection was performed using single differential surface electrodes. The EMG signal was recorded and expressed as root mean square, which was normalized by the maximum voluntary isometric contraction. The data were subjected to parametric statistical analysis, using the analysis of variance (ANOVA) for repeated measures. The results showed that the BOSU provided greater activity in the ankle muscles than the most proprioceptive devices, accordingly, the BOSU is a device that should be employed to diversify programs of prevention/rehabilitation for lower limb injuries, preferentially in advanced stages of these approaches.


As entorses de tornozelo são comumente relacionadas com atividades desportivas e muitas vezes estão associados com diminuição no controle sensório-motor, incluindo a propriocepção, força muscular e equilíbrio. A utilização de superfícies instáveis nas áreas de reabilitação e condicionamento físico geral têm sido eficaz no aumento da eficiência sensorial dos tecidos moles que estabilizam o joelho e tornozelo e na melhora da cocontração agonistaantagonista. Desta forma, o objetivo deste estudo foi analisar a atividade eletromiográfica dos músculos tibial anterior (TA), fibular longo (FL) e cabeça medial do gastrocnêmio (GM) durante o exercício proprioceptivo com bosu e comparar com diferentes aparelhos tradicionalmente utilizados (balancinho, cama elástica e disco proprioceptivo). Onze voluntários do gênero masculino foram recrutados e a coleta de dados foi realizada utilizando-se eletrodos de superfície diferencial simples. O sinal eletromiográfico foi quantificado pela Raiz Quadrada da Média (root mean square -RMS) e normalizado pela Contração Isométrica Voluntária Máxima. Os dados obtidos foram submetidos à análise estatística paramétrica, empregando-se teste de análise de variância de medidas repetidas (ANOVA). Os resultados demonstraram que o bosu proporcionou maior atividade nos músculos do tornozelo em relação a maioria dos aparelhos proprioceptivos , desta forma, o bosu é um dispositivo que deve ser utilizado para diversificar um programa de prevenção ou reabilitação de lesões de membro inferior, preferencialmente em estágios avançados destes programas.

RESUMO

In this study, the effects of acupuncture in comparison with flat occlusal plane appliance were evaluated in patient with myogenic temporomandibular dysfunction (TMD). The sample consisted of 40 women with TMD and unbalanced energy predominance of Yang Liver Ascension, selected using the Renying and Cunkou pulses, randomly divided into two groups: acupuncture and splint. The effect of treatments on the masseter and anterior temporal muscles was evaluated after 4 weeks of treatment, by means of electromyographic activity (root mean square) and pain pressure threshold. Pain intensity was measured using the visual analog scale, and range of mouth opening was evaluated using a millimeter ruler. All evaluations were performed at the beginning and end of the treatment. Visual analog scale score was reduced equally in the two groups (p < 0001), and the increase in range of mouth opening was significant in both groups. A significant difference was detected only in pain pressure threshold of the left masseter in the acupuncture group (p < 0.05). Only root mean square in the at rest position of the right temporal muscle diminished in the final stage of the splint group (p < 0.05). Both treatments reduced the pain intensity of myogenic TMD in the short term and may be considered strategies for control of chronic pain related to TMD.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: Depression and somatization are emotional features present in chronic temporomandibular disorder pain patients. This study aimed at evaluating results after acupuncture on psychological aspects of females with chronic muscle temporomandibular disorder pain. METHODS: Sample was made up of 40 females, aged between 18 and 45 years, submitted to two procedures: acupuncture and splint. Patients were evaluated for one month by the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire Axis II before and after treatment. Treatment expectation before treatment was also evaluated by a visual analog scale with verbal anchors: negative expectation and positive expectation. RESULTS: There has been chronic pain improvement in 53.3% of acupuncture patients and in 60% of splint patients. For severe depression, 11.1% of acupuncture and 50% of splint patients have improved. Patients with severe somatization had 16.7% improvement with acupuncture and 44.4% with splint. There has been negative correlation (p<0.05) between treatment expectation and somatization (including and excluding pain items) for the acupuncture group. CONCLUSION: Both groups have improved some psychological aspects (depression and somatization) after a short period of treatment. .


RESUMO JUSTIFICATIVA E OBJETIVOS: Depressão e somatização são características emocionais presentes em pacientes com dor crônica de disfunção temporomandibular. O objetivo deste estudo foi avaliar os resultados obtidos após acupuntura nos aspectos psicológicos em mulheres com dor crônica de disfunção temporomandibular muscular. MÉTODOS: A amostra foi de 40 mulheres, com idades entre 18 e 45 anos, submetidas a dois tratamentos: acupuntura e splint. Foram avaliadas em um período de um mês através do questionário do Eixo II do Research Diagnostic Criteria for Temporomandibular Disorders no pré e pós-tratamento. Também se avaliou a expectativa de tratamento no pré-tratamento através de uma escala analógica visual, com as âncoras verbais: expectativa negativa e expectativa positiva. RESULTADOS: Observou-se melhora no grau de dor crônica em 53,3% das pacientes da acupuntura e em 60% do splint. Para depressão grau grave a melhora foi em 11,1% das pacientes da acupuntura e 50% do splint. As pacientes com somatização grau grave apresentaram melhora de 16,7% na acupuntura e 44,4% no splint. Houve correlação negativa (p<0,05) entre a expectativa de tratamento e somatização (incluindo e excluindo itens de dor) no grupo acupuntura. CONCLUSÃO: Em ambos os grupos houve melhora de alguns dos aspectos psicológicos (depressão e somatização) após curto período de tratamento. .

RESUMO

[Purpose] Temporomandibular disorder is one of the many different adverse health conditions that can be triggered by stress. Therefore, a biopsychosocial model has been proposed to characterize the multifactorial nature of temporomandibular disorder. The aim of the present study was investigate the correlation of salivary cortisol levels with the activities of the masseter and anterior temporal muscles of patients with different degrees of temporomandibular disorder. [Subjects and Methods] Forty-nine women between 18 and 40 years of age with a diagnosis of myogenous temporomandibular disorder based on the Research Diagnostic Criteria for temporomandibular disorders were evaluated using the Fonseca Index to determine the degree of the disorder. Salivary cortisol levels were determined and surface electromyography was used to evaluate electrical activity in the masticatory muscles. [Results] Positive correlations were found among the degree of temporomandibular disorder, electromyographic activity and salivary cortisol: as women with more severe temporomandibular disorder had greater electrical activity in the muscles analyzed, especially the anterior temporal muscle, and higher levels of cortisol. [Conclusion] Muscle activity was greater among individuals with severe temporomandibular disorder and positive correlations were found among electromyographic activity, salivary cortisol and the degree of temporomandibular disorder severity.

RESUMO

BACKGROUND AND OBJECTIVES: Head, face and neck pain affects a large portion of the world population, however there are few studies reporting this condition in general Brazilian population. This study aimed at investigating the prevalence of head, face and neck pain and its impact on the quality of life of adults of Piracicaba city, São Paulo. METHODS: The sample was made up of 400 volunteers of both genders, aged between 20 and 50 years, who were randomly approached in six crossing points of the city. Socio-demographic, pain prevalence, location, frequency, duration and severity, and self-perception of quality of life data were collected by means of anonymous self-applied questionnaires: Orofacial Pain Questionnaire and WHOQOL-BREF. RESULTS: Pain prevalence was 54.75%, of predominantly severe intensity (21.30%), daily recurrence (41.10%) and present for more than six months (91.32%). Most affected region was the head (36%) being the intraoral region the less frequently reported (6%). There has been no significant association between pain and factors such as age, economic level and education (p>0.05); however there has been significant prevalence among females. No pain was frequently associated to better quality of life (p<0.05). Volunteers reporting pain were more unhappy with quality of sleep (p<0.05), however there has been no significant association with the frequency of negative feelings. CONCLUSION: The study has identified high prevalence of head, face and neck pain, significant morbidity of people affected by this condition and its negative impact on quality of life. .


JUSTIFICATIVA E OBJETIVOS: As dores que acometem o segmento cefálico afetam grande parte da população mundial, porém são poucos os trabalhos que retratam essa condição na população geral do Brasil. O objetivo deste estudo foi investigar a prevalência de dor no segmento cefálico e seu impacto sobre a qualidade de vida de adultos do município de Piracicaba, São Paulo. MÉTODOS: A amostra foi composta por 400 voluntários de ambos os gêneros, com idade entre 20 e 50 anos que foram aleatoriamente abordados em seis pontos de passagem do município. A coleta de dados sócio-demográficos, prevalência, localização, frequência, duração, gravidade da dor e autopercepção da qualidade de vida foi realizada por meio de questionários anônimos autoaplicados, o Questionário de Dor Orofacial e o WHOQOL-BREF. RESULTADOS: A prevalência de dor foi de 54,75%, de intensidade predominantemente intensa (21,30%), recorrência diária (41,10%) e presente há mais de seis meses (91,32%). A região mais acometida foi a cabeça (36%) sendo a região intraoral menos frequentemente apontada (6%). Não se observou associação significativa entre a presença de dor e fatores como idade, nível econômico e escolaridade (p>0,05), porém houve significativa prevalência de dor entre as mulheres. A ausência de dor foi frequentemente associada à melhor qualidade de vida (p<0,05). Voluntários que relataram dor apresentaram maior insatisfação com a qualidade do sono (p<0,05), porém não foi observada associação significativa com a frequência de sentimentos negativos. CONCLUSÃO: O estudo identificou alta prevalência de dor no segmento cefálico, significante morbidade das pessoas acometidas por essa condição e seu impacto negativo sobre a qualidade de vida. .
