Introdução: A atividade muscular mastigatória rítmica (AMMR) é classificada como distúrbio de movimento estereotipado, caracterizada pelo ranger ou o apertar dos dentes durante o sono, também denominada bruxismo do sono (BS). A prática clínica sugere que o bruxismo seja um fator de risco para a dor orofacial e o cansaço muscular. Não existe tratamento definitivo para ele, mas sim medidas preventivas para evitar suas complicações, (dor orofacial, desgaste dental, zumbido, entre outras). Dispositivos intraorais são comumente utilizados no controle do bruxismo. Objetivos: O objetivo deste estudo foi avaliar a modulação do bruxismo do sono e da dor muscular mastigatória após 45 dias de uso de placas intraorais. Pacientes: 21 pacientes que relatavam sons de ranger de dentes durante o sono e também apresentavam dor muscular mastigatória; foram tratados com dispositivos intraorais (placa oclusal e não-oclusal) e divididos em 3 grupos: Grupo 1 (n=7) placa oclusal, Grupo 2 (n=7) placa não-oclusal e Grupo 3 (n=7) pacientes aguardando tratamento (grupo controle). Materiais e métodos: todos os pacientes foram submetidos à avaliação sistemática que constou de: 1-protocolo EDOF-HC; 2-Escala Visual Analógica; 3-RDC/TMD; 4-questionário específico do bruxismo do sono e 5- ortopantografia) e quatro noites de polissonografia (PSG), (noite de habituação, noite de diagnóstico, após 7dias e após 45 dias da utilização de dispositivos orais). ANOVA e o Teste Exato de Fischer foram usados para análise estatística. Resultados: Após 45 dias de avaliação houve redução da dor dos pacientes que utilizaram placa oclusal e não oclusal (Grupo 1 p=0,001, Grupo 2 p=0,001) quando comparada à noite inicial, entretanto, todos os pacientes do Grupo 3 continuaram com dor orofacial e cansaço muscular. Com exceção do tempo de estágio do sono REM, não houve diferenças estatísticas significantes nas variáveis do sono obtidas pela avaliação das PSG de todos os pacientes. O número de AMMR aumentou no Grupo1 (p=0,002), comparado ao Grupo 3 (p=0,900), entre a avaliação inicial e após 45 dias. Conclusão: A dor muscular mastigtatória foi reduzida nos grupos que utilizaram as placa oclusal e nãooclusal quando comparados àqueles que não a utilizaram, após 45 dias. Foi observado um aumento estatisticamente significante no número de atividade muscular mastigatória rítmica nas polissonografias dos pacientes que utilizaram placa oclusal. O mecanismo que sugere esse aumento é a redução da dor muscular mastigatória / Introduction: The rhythmic masticatory miofascial activity (RMMA) is classified as a mandibular movement disorder characterized by jaw clenching and tooth grinding during sleep so called sleep bruxism. Clinical practice sugests that bruxism is a risk factor of pain and muscular fatigue. There is no definitive treatment but certain preventive measures to avoid complications (orofacial pain, ringing in ears, tooth wear, and others). Intraoral devices are commonly used for bruxism and pain control. Objectives: The purpose of the present study was to evaluate the modulation of rhythmic masticatory mandibular activity (RMMA) and temporomandibular disorder pain (TMDP) of patients after 45 consecutive days of use of an intraoral device. Patients: 21 patients with TMDP and reported tooth grinding sounds during sleep and pain were randomized and divided into the following 3 groups: Group 1 (n=7) intraoral splint, Group 2 (n=7) palatal splint, and Group 3 (n=7) patients awaiting treatment. Methods: All patients were submitted to an interview, a systematic evaluation (EDOF-HC protocol, Visual Analogic Scale, RDC/TMD, orthopanthomography) and three PSG (baseline, 7days, and 45 days after treatment onset). ANOVA and Chi- Square tests were used for statistical analyses. Results: At 45th -day evaluation, TMDP reduced (Group A, p=0.001; Group B, p=0.001) when compared to baseline; Group 1 and Group 2 were free from pain after 45 days. On the other hand, all patients in Group 3 continued with TMDP and muscle fatigue. There were differences between groups in REM sleep data obtained by PSG evaluations, and the number of RMMA increased in Group 1 (p=0.002) compared to Group 3 (p=0.900) between baseline and 45th -day evaluation. Conclusions: TMDP was reduced in the groups that used intraoral and palatal splints when compared to non-users after 45 days; there were no changes in sleep parameters, and therefore there was an increase in the number of RMMA as shown by PSG studies among the patients that used intraoral splints. The suggested mechanism for that increase is the reduction of TMDP

Uma vez que o hábito de ranger de dentes pode levar a edentações na língua, este estudo avaliou a força da língua em pacientes bruxistas antes e após a terapia por meio de placas oclusais estabilizadoras. Para tanto, voluntários foram selecionados na Faculdade de Odontologia de Piracicaba - UNICAMP e separados em dois grupos: (1) com bruxismo (experimental, n=20), e (2) sem bruxismo (controle, n=20), selecionados segundo os critérios de inclusão. O diagnóstico de bruxismo foi realizado por meio de exame clínico com identificação de sinais e sintomas e por meio da utilização de eletromiografia portátil, Bitestrip®. Posteriormente, todos os voluntários tiveram a força da língua avaliada por meio de sensores de pressão (T0 ¿ baseline). A seguir, os voluntários do grupo experimental receberam placa oclusal estabilizadora, como controle para o bruxismo; e os do grupo controle receberam placa palatina (placebo), sendo todos os voluntários instruídos a utilizá-las durante o sono. Após 30 e 60 dias de uso das placas, a força da língua foi reavaliada. Os resultados obtidos foram submetidos à análise de variância para medidas repetidas, seguido pelo teste de Tukey para comparações múltiplas. Todos os cálculos foram efetuados com uso do sistema SAS e o nível de significância adotado foi de 5%. Foi verificado que pacientes com bruxismo apresentaram os maiores valores de força da língua (P=0,0027). A utilização de placa oclusal estabilizadora e de placa palatina reduziu (P<0,05) a força máxima da língua para o grupo experimental e controle, que ocorreu independentemente da região da língua. Em acréscimo, observou-se que a língua apresenta maior força na arcada dentária inferior (P<0,05). Pode-se concluir que indivíduos bruxistas apresentam maior força da língua quando comparados àqueles com ausência desse hábito, e o uso da placa oclusal estabilizadora e placa palatina são capazes de diminuir a força da língua / Abstract: Bruxism is a subject of intense research in the dental field and it is correlated with emotional factors and stress events experienced by individuals. Once the habit of teeth grinding can lead to indentations on the tongue, this study assessed the strength of the tongue in bruxism patients before and after therapy by occlusal splints. Volunteers were recruited from Piracicaba Dental School - UNICAMP and divided into two groups: (1) volunteers with bruxism, (experimental, n=20) and (2) volunteers without bruxism (control, n=20), selected according to the inclusion criteria. The diagnosis of bruxism was performed by clinical examination and the use of eletromiographic disposable Bitestrip®. Subsequently, all participants underwent a test to verify the tongue strength by means of pressure sensors (T0 ¿ baseline). Next, the volunteers in the experimental group received occlusal splints as a treatment for bruxism, and those from the control group received an oral appliance (placebo). Subjects from both groups were instructed to use splints during night. After 30 and 60 days of splint use, tongue pressure was reassessed. The results obtained were submited to analysis of variance for repeated measures, followed by Tukey test for multiple comparisons. All calculations were performed using the SAS system and the level of significance was set at 5%. Subjects with bruxism showed the highest values of tongue strength (P=0.0027). The use of occlusal splints and oral appliance reduced (P <0.05) the maximum tongue strenght for experimental and control groups, independent of tongue region. In addition, it was observed that tongue has greater strength in mandibular jaw (P <0.05). In conclution, subjects with bruxism have a higher tongue strength compared with non-bruxers and the use of occlusal splints and oral appliance are able to decrease tongue strength / Mestrado / Protese Dental / Mestra em Clínica Odontológica

>Magister Scientiae - MSc / Splinting is one of the many strategies used globally for managing neuromuscular impairments related to cerebral palsy. In Uganda, some children with cerebral palsy who have been provided with splints return to the physiotherapy department with contractures or deformities. A qualitative research methodological approach was used to understand and describe the experiences of caregivers of children with cerebral palsy regarding splinting in Uganda. The theoretical framework used was the bio-psychosocial model of disability. Purposive sampling was used to select 24 caregivers of children with spastic cerebral palsy who received splints in 2010 at two research settings in Uganda. In-depth interviews were conducted with all the participants at their homes using an interview guide. The data collected was transcribed verbatim and translated from Luganda to English. Inductive content analysis was used to analyse the data. Six themes concerning experiences emerged, namely: caregivers‟ expectations and beliefs; acquisition of splints; knowledge and skills; attitudes to splinting; compliance and benefits of splinting. The results of this study show the overwhelming challenges caregivers face while their children require splinting. When considering providing splints to children, the results highlight the need, to take into account the personal (child) factors, the splint characteristics and the environmental (family and community) factors. There is a need to provide information on splints to both the children with cerebral palsy and their caregivers.

Foram submetidos ao exame clinico, de acordo com o protocolo clínico do CETASE (Centro de Estudos e Tratamento das Alterações Funcionais do Sistema Estomatognático) da FOP - Unicamp, e a exames radiográficos complementares. As avaliações eletromiográficas foram realizadas simultânea e bilateralmente, no período inicial e aos 30, 60 e 90 dias de tratamento, com a mandíbula nas posições de repouso e fechamento isométrico com resistência. Os resultados obtidos foram avaliados pelos testes t de Student e pela Correlação de Spearman. Na situação de repouso houve um aumento significante na atividade eletromiográfica do músculo esternocleidomastoideo direito, quando comparados os períodos inicial e após 60 e 90 dias (p=0,03), e nos músculos trapézio médio direito após 60 dias (p=0,03), e esquerdo, após 90 dias de tratamento (p=0,04). Na situação de fechamento isométrico com resistência resultados significantes foram encontrados pelo teste t para as atividades eletromiográficas dos músculos suprahioideos direito (p=0,04) e trapézio médio direito (p=0,04) e esquerdo (p=0,02), após 90 dias de tratamento. Uma correlação significante pôde ser observada quando comparamos bilateralmente todos os músculos avaliados, nas duas situações (p<0,05). Após a terapia com aparelhos oclusais planos ocorreu uma equalização funcional significativa na atividade eletromiográfica dos músculos cervicais e supra-hioideos, podendo sugerir que a alteração na posição mandibular influencia na atividade elétrica dos músculos cervicais / Abstract: The aim of this study was to evaluate the electromyographic activity of the suprahyoid, sternocleidomastoid and trapezius muscles in 15 edentulous volunteers, with a low vertical dimension of occlusion (VDO), temporomandibular disorder (TMD) and treated with plan occlusal splints. Patients were undergone to clinical examination, according to the clinical protocol of CETASE (Functional Stomatognathic Disorders Study Center) FOP - Unicamp, and additional radiographic exams. Electromyographic evaluations were performed simultaneously and bilateral, before the beginning of the treatment and at 30, 60 and 90 days of treatment, with the jaw at rest position and isometric closure with resistance. The results were evaluated by Student's t-test and Spearman's correlation. In the resting position there was a significant increase in EMG activity of right sternocleidomastoid muscle comparing to the beginning and after 60 and 90 days of treatment (p=0.03), and in right middle trapezius after 60 days of treatment (p=0.03), and left after 90 days of treatment (p=0.04). Relating to isometric closure with resistance significant results were found by t-test for the electromyographic activity of the right suprahyoid muscles (p=0.04) and right (p=0.04) and left middle trapezius (p=0.02) at 90 days after treatment. A significant correlation was observed when comparing bilaterally all muscles in both conditions (p<0.05). After the plan occlusal splint therapy, there was a significant functional equalization of the electromyographic activity of neck and suprahyoid muscles, suggesting that changes in mandible position can influence the electrical activity of cervical muscles / Doutorado / Protese Dental / Doutor em Clínica Odontológica

Pesquisadores têm relatado em trabalhos com pacientes portadores de sintomatologia crônica, a presença desses (chamados distúrbios psiquiátricos menores); porém, ainda não há um consenso sobre a influência destes na manifestação clínica desta patologia. O objetivo deste trabalho foi avaliar a evolução da manifestação dos distúrbios psiquiátricos menores em pacientes portadores de DTM, tratados com aparelhos de superfície oclusal plana e reabilitação oral. Foram selecionados 60 pacientes, do Curso de Especialização em Prótese Dental da Faculdade de Odontologia de Piracicaba, portadores de DTM e com necessidade de reabilitação protética. Os voluntários foram subdivididos em dois grupos: controle e tratado; sendo que respectivamente, o primeiro não recebeu tratamento e o segundo recebeu tratamento com aparelhos de superfície oclusal plana e reabilitação oral. Todos os voluntários do grupo tratado foram submetidos ao questionário anamnésico que faz parte da ficha clínica do CETASE e às avaliações psicológicas contidas no Questionário de Saúde Geral de Goldberg (QSG), antes e após o período de tratamento; os voluntários do grupo controle foram submetidos à mesma avaliação psicológica do grupo anterior; entretanto, como não recebeu tratamento, estabelecemos duas avaliações, uma antes e outra após 20 meses, conjuntamente ao grupo que recebeu tratamento. Os resultados revelaram que houve diferenças estatisticamente significantes para as variáveis estresse psíquico (SP) e distúrbios psicossomáticos (DP) no grupo tratado para o sexo feminino. Neste mesmo grupo, nos pacientes do sexo masculino, verificaram-se diferenças estatisticamente significantes para as variáveis distúrbios psicossomáticos (DP) e saúde geral (SG). Conclui-se que a terapêutica utilizada interferiu positivamente na incidência dos distúrbios psiquiátricos menores, em pacientes portadores de DTM / Abstract: The role of psychological factors in the temporomandibular disorders (TMD), like depression, anxiety, stress have been emphatic in the literature. Many authors have been related on their patients with cronic sintomatic the presence of these factors (called minor psychiatric disturbances); however, there isn't agreement about the influence of these factors on the TMD. The aim of this study is to verify the evolution of the prevalence about the minor psychiatric disturbances in patients with TMD, treated using occlusal plane splints and oral rehabilitation. It was selected 60 patients, who were voluntarily seeking for dental treatment at the Piracicaba Dentistry Scholl-UNICAMP with TMD diagnostic and needed oral rehabilitation. The volunteers were divided into two groups equality: control and treated group. The control group didn't received any kind of treatment and the treated group was treated with occlusal plane splints and oral rehabilitation. All the volunteers were submitted to an anamnesic questionnaire that is part of the clinical index of Treatment Center (CETASE- FOP/UNICAMP). The questionnaire includes a patient spontaneous discription and direct questions related to TMJ, masticatory muscles and unespecific relates. After the anamnesic questionnaire the patients were submitted to the GHQ (General Health Questionnaire), that evaluates the absence of non psychotic disturbances psychiatry (minor psychiatric disturbances), after the treatment both groups were submitted to both questionaires again (20 months after the first aplication). The results showed significant differences to psychic stress and psychosomatic disturbances in the treated group, female sex and psychosomatic disturbances and general health to male sex. The conclusions of this study, based on the obtained results is that the treatment interfered positively on the incidence of minor psychiatric disturbances in patients with TMD / Doutorado / Protese Dental / Doutor em Clínica Odontológica

The aim of this study was to establish whether a splint programme is effective in preventing the deterioration of already evident swan neck and boutonniere deformities in rheumatoid arthritis (RA). A randomised clinical trial was done on 34 RA patients with swan neck and 34 RA patients with boutonniere deformities. The literature revealed that several factors such as age, gender, socio-economic status, time after onset of the illness and lifestyle could influence results. Care was taken to allocate, as far as possible equal numbers of patients with these attributes to the experimental and control groups. It became clear from the literature that swan neck and boutonniere deformities could manifest themselves in different forms and stages or grades of deterioration. Various splints to halt the downward spiral of the deformity were recommended, without proper scientific verification, by the authors. No specifications as to which splint was recommended for which form or grade of deformity or instructions for wearing of the splints were included. For the study the PIP hyperextension splint and the three-point-PIP extension splint was chosen for the swan neck and boutonniere deformities respectively. Patients were followed up for one year. Results were marginally positive for the prevent ion of swan neck deformities by the hyperextension splint programme, but results for the three-point PIP extension splint programmes were negative for grade I boutonniere deformities. Loss of flexor muscle strength was evident in almost all the groups (experimental and control) but more so for grade I swan neck and grade I boutonniere deformities. The variability of measurements were found to be large. Many possible sources of variation were identified, which included biological differences between people, different courses the illness could take and a weak test-retest reliability of some goniometer measurements. This fact and the relatively small sample subgroups caused some results to be not significant on the 5% level. From the significant findings, and other not significant tendencies that were too persistent to ignore, linked to the different manifestations and grades of swan neck and boutonniere deformities, recommendations were made. These suggestions will have to be tested by experimentation.

The identification of risk factors associated with overuse injuries, specifically Medial Tibial Stress Syndrome (MTSS) and Tibial Stress Fractures (TSF), may help professionals with management and prevention of these injuries. The purpose of this study was to identify risk factors associated with MTSS and TSF in female intercollegiate athletes. This study used a mulitifactorial, prospective design for 13-26 weeks. Thirty-nine Division I intercollegiate female student-athletes in volleyball, soccer, and track were examined. Anatomical, physiological (eating disorder and menstrual history), and training (duration and recovery time) characteristics were examined as possible risk factors. Only two injuries were reported during the study; therefore, analysis for risk factors was not possible. Descriptive statistics for the dependent variables were calculated, and comparisons across sport were performed. Differences in leg length values and dorsiflexion ROM were observed across sports. No conclusions could be drawn regarding possible risk factors for MTSS and TSF in this population.

Introduction: Foot over-pronation, attributable to Tibialis Posterior (TP) muscle weakness, is a possible cause of medial tibial stress syndrome (MTSS)3. Taping may provide a viable alternative for a dysfunctional TP and its associated navicular drop (ND). The most commonly used Augmented LowDye (ALD) technique has shown to prevent ND, but is time- and cost- intensive, leading us to explore an alternative technique. The purpose of this study was to assess the effectiveness of a new, anti-pronation (AP) taping technique, as compared to the ALD, to (a) reduce or prevent ND and (b) cause a lateral shift in the center of pressure (COP) measures. Methods: This is a 2 (tape techniques) by 3 (time: baseline, tape/pre-exercise, and tape/post-exercise) controlled laboratory study design. Twenty symptomatic (ND >/= 10 mm) college-age subjects were prepared with one of the 2 tape techniques and/or control and performed the ND test three times and walk across a pressure mat five times. Then the participants fatigued the tape by walking on a treadmill for 15 minutes at 3.0 mph at 0% grade and ND and pressure mat readings were recorded again. A within and within ANOVA allowed for the examination of between and within comparisons and a functional analysis (lateral shift as a function of time) on the mat-generated data were done p<.05. Results: Results revealed significant differences across times, and a times-by-tape technique interaction but differences between tape techniques were not significant. M and SD and indicate that while both taping techniques reduced ND, only the AP technique was significantly different (HSDTukey (3,76)=1.44, p<.01) for every comparison other than AP pre-exercise, the mean lateral shift for the treatment was not significantly different from the control across any part of the normalized stance phase, but was significantly lower than the control in the 30-90% interval in the AP pre-exercise. Discussion: The AP technique not only controlled ND but also resulted in an increase in lateral excursion of the COP line during that portion of the stance phase associated with the structures and functions of the TP. Both techniques can be appropriately used but that the AP can be used with more confidence in its effectiveness. The MatScan has allowed examination of forefoot pronation in the horizontal plane, not just the vertical plane, yielding a more holistic analysis of forefoot pronation. Being able to analyze data in a functional fashion (i.e., lateral shift as a function of time) could allow researchers greater insights to the complex relationships between biomechanical movement and appropriate interventions.

Introduction: The New Balance Core Low Cut Sock (New Balance Athletic Shoe, Inc. · Boston, MA United States) is one of many arch support socks out in the market. These socks have an elastic portion, called a Stability Fit Arch Support & Hold technology, which has been incorporated into the arch area of the sock. The company makes the following claim that the socks provide, "Gentle compression to support the arch, relieving arch-related pain and discomfort."1 If these socks do provide adequate arch support, then they would allow individuals the ability to have an inexpensive method of arch support that is easy to apply and use. The purpose of this study is to test the effectiveness of these socks in (a) navicular drop (b) static pressure insole pressure profiles and (c) dynamic (walking and running) pressure insole pressure profiles. Methods: Eighteen symptomatic, college age (age 18-26) subjects were used in this study (seven male, eleven female), with symptomatic being defined as a navicular drop greater than or equal to 10 mm. Measurements were collected for both the navicular drop, and F-Scan insole data, for both static and dynamic stance. For walking and running trials, heel strike and toe off were identified by the Tekscan System and COP excursion coordinates evaluated throughout the stance phase. The COP coordinates were exported then compared over the stance phase. A series of functional analyses was used to assess the between group differences. A paired t-test was used to assess the within group differences. Results: Results indicate that the arch support socks were not significantly different from the control (regular socks) along any part of the foot strike (95% confidence) in any of the conditions (standing, walking or running). Results from the paired t-test revealed no significant differences in navicular drop between sock types (p = .379). Discussion: This study found that the elastic band in the New Balance socks did not provide increased support to the medial arch of the foot compared to the control sock in either the navicular drop paired t-test or the functional analysis of the static and dynamic data. The authors could not find any other comparable study on these kinds of socks. Compared to other reports, using both orthotic inserts and tape, ND was reduced, unlike the results found in the present study. 2 Our data are inconsistent with the idea that increased elastic support to the midfoot by these socks provides significant arch support. The authors would suggest another form of arch support such as orthotics or taping to aid on arch support rather than these socks.
