ABSTRACT

Introducción: El p-clorofenol alcanforado es un derivado clorofenólico de uso común como medicación intraconducto en Endodoncia. Son escasos los reportes científicos sobre sus efectos en la musculatura lisa vascular arterial y la regulación del flujo sanguíneo local. Objetivo: Determinar el efecto del p-clorofenol alcanforado sobre la dinámica contráctil del músculo liso vascular arterial en el tiempo. Método: Se realizó una investigación experimental preclínica utilizando 14 anillos de aorta obtenidos de ratas Wistar. Los anillos se colocaron en baño de órganos y se preactivaron con noradrenalina, registrándose luego la tensión desarrollada por el músculo liso vascular tras la adición de p-clorofenol alcanforado durante diferentes intervalos de tiempo. Resultados: El 51,4 porciento de la musculatura lisa vascular se relajó por la acción del p-clorofenol alcanforado. El mayor descenso del tono vascular se produjo entre el tercer y quinto minuto de añadido el medicamento. Las pruebas de Wilcoxon de los rangos con signos evidenciaron diferencias significativas entre la tensión base inicial y la registrada en los diferentes intervalos de tiempo estudiados. Conclusiones: el p-clorofenol alcanforado, induce in vitro, relajación del músculo liso arterial a través de un acoplamiento excitación-contracción de tipo farmacomecánico, la cual se incrementa en función del tiempo(AU).


Introduction: Camphorated p-chlorophenol is a chlorophenolic derivative commonly used as an intra-oral medication in endodontics. Scientific reports on its effects in arterial vascular smooth muscle and local blood flow regulation are scarce. Objective: To determine the effect of camphorated p-chlorophenol on the contractile dynamics of arterial vascular smooth muscle. Method: An experimental and preclinical research was conducted with the use of 14 aortic rings of Wistar rats. The rings were placed in an organ bath and preactivated with noradrenaline, and the tension developed by the vascular smooth muscle at different time intervals was recorded after induction of camphorated p-chlorophenol. Results: Most of the vascular smooth muscle (51.4 percent) relaxed with the use of camphorated p-chlorophenol. The greatest decrease in vascular tone occurred between the third and fifth minute after use the drug. Wilcoxon rank tests showed significant differences between tension observed at baseline and those recorded at the different time intervals studied. Conclusions: Camphorated p-chlorophenol, induces in vitro, relax the arterial smooth muscle through a pharmacomechanical excitation-contraction link, which increases according to the time(AU).

ABSTRACT

RESUMO Objetivo identificar sinais e sintomas de DTM, bem como analisar os resultados de parâmetros vocais, do exame clínico físico de palpação muscular, da autopercepção de sintomas vocais, dor e fadiga vocal de mulheres com DTM e comparar com mulheres vocalmente saudáveis. Métodos estudo transversal com 45 mulheres (23 com DTM e 22 controles), mediana de idade similar entre os grupos. A avaliação fonoaudiológica e otorrinolaringológica determinaram o diagnóstico de DTM. Todas as participantes responderam aos protocolos Escala de Sintomas Vocais (ESV), Índice de Fadiga Vocal (IFV) e Questionário Nórdico de Sintomas Osteomusculares (QNSO). Elas também foram avaliadas pelo exame de palpação da musculatura perilaríngea, avaliação perceptivo-auditiva e análise acústica da voz da frequência fundamental. A amostra de fala incluiu vogais "a", "i" e "é" sustentadas e fala encadeada, gravada em ambiente silente, e submetida à avaliação perceptivo-auditiva por três juízes. Na análise acústica, a frequência fundamental e tempos máximos de fonação foram extraídos. Resultados O grupo DTM apresentou piores resultados na ESV, na IFV e no QNSO, além de maior resistência à palpação e posição vertical de laringe alta. Os parâmetros vocais também apresentaram maior desvio na DTM, exceto para a frequência fundamental. Não houve relação entre sintomas vocais, fadiga ou dor com o grau geral da disfonia no grupo DTM, indicando sintomas importantes em desvios vocais leves ou moderados. Conclusão mulheres com DTM apresentaram sintomas vocais, fadiga vocal, dor muscular, resistência à palpação e parâmetros vocais desviados quando comparadas às mulheres vocalmente saudáveis.


ABSTRACT Purpose To identify muscle tension dysphonia (MTD) signs and symptoms, as well as to analyze the results of vocal parameters, the physical clinical examination of muscle palpation, the self-perception of vocal symptoms, vocal pain, and fatigue of women with MTD and compare them with women with healthy voices. Methods a cross-sectional study with 45 women (23 with MTD and 22 controls), similar median age between groups. The speech-language and otorhinolaryngological evaluation determined the diagnosis of MTD. All participants responded to the Voice Symptoms Scale (VoiSS), Vocal Fatigue Index (VFI), and Nordic Musculoskeletal Questionnaire (NMQ) protocols. They were also assessed by a palpatory evaluation of the perilaryngeal musculature, auditory-perceptual evaluation, and acoustic analysis of the voice fundamental frequency. The speech sample included sustained vowels "a", "i" and "e" and connected speech, recorded in a silent environment, and submitted to auditory-perceptual evaluation by three judges. In the acoustic analysis, the fundamental frequency and maximum phonation times were extracted. Results The MTD group had worse results in VoiSS, VFI, and NMQ, in addition to greater resistance to palpation and a high vertical position of the larynx. The vocal parameters also showed greater deviation in the MTD group, except for the fundamental frequency. There was no relationship between vocal symptoms, fatigue, or pain with the general degree of dysphonia in the MTD group, indicating important symptoms in mild or moderate vocal deviations. Conclusion women with MTD presented vocal symptoms, vocal fatigue, muscle pain, resistance to palpation and deviated vocal parameters when compared to vocally healthy women.

ABSTRACT

Introdução: Durante sua carreira o cantor lírico sofre grande demanda e consequente alteração da coordenação dos músculos respiratórios, porém não se sabe se estas exigências podem alterar a mobilidade e tonicidade no principal músculo da respiração, o diafragma. Objetivos: Avaliar e comparar a tonicidade e a mobilidade do diafragma de cantores líricos profissionais e de não-cantores. Participaram do estudo 15 cantores líricos profissionais em plena carreira e 24 adultos não-cantores com idades e IMCs equivalentes. Métodos: Duas avaliações foram empregadas: para avaliar a mobilidade costal foi utilizada a parte referente a avaliação desse parâmetro da Manual Evaluation of the Diaphragm Scale (MED Scale); para avaliar a tonicidade diafragmática a avaliação descrita por Rial e Pinsach em 2015. Resultados: Os resultados mostraram que a distribuição da avaliação manual do diafragma no grupo dos cantores apresentou distribuição significativamente diferente, tendo p < 0,05, com relação à tonicidade bilateral do diafragma, apresentando maior hipertonicidade em relação ao grupo controle, e que não houve diferenças significativas em relação à mobilidade. Conclusão: Os gestos artísticos usados pelos cantores líricos profissionais afetam a tonicidade do diafragma. (AU)


Introduction: The professional lyrical singers during their careers suffer great demand and consequent alteration of the coordination of the respiratory muscles, however it is not known if these requirements can alter the mobility and tonicity in the main muscle of the breath, the diaphragm. Objectives: To evaluate and compare diaphragm tonicity and mobility of professional lyric singers and non-singers. The study included 15 professional lyric singers in their full careers and 24 non-singing adults of equivalent ages and BMIs. Methods: Two forms of manual evaluation of the diaphragm were used: to assess costal mobility, the part of the manual evaluation to evaluate this parameter was used the Manual Evaluation of the Diaphragm Scale (MED Scale); and to evaluate the diaphragmatic tonicity the evaluation described by Rial and Pinsach in 2015. Results: The results showed that the distribution of the manual evaluation of the diaphragm in the group of singers presented a significantly different distribution, with p < 0,05, in relation to the bilateral diaphragm tonicity, presenting them with greater hypertonicity in relation to the control group, and that there were no significant differences regarding mobility. Conclusion: The artistic gestures used by professional lyric singers affect the tone of the diaphragm. (AU)

ABSTRACT

Manual tests in clinical investigation must be supported by anatomical and physiological findings in order to obtain an objective information. The application of different mandibular positions in children obtains a variation in the 'hip rotators test' (p < 0.001). The possible relationships behind the muscle tone of the external rotators of the hips and the stomatognathic system are exposed, with special attention on the fascial tissue and its morphological characteristics. Despite these anatomical and physiological connections, there is no further evidence of a strong cause-effect relationship in this test.


Las pruebas manuales en la investigación clínica deben estar respaldadas por hallazgos anatómicos y fisiológicos para obtener una información objetiva. La aplicación de diferentes posiciones mandibulares en niños muestra una variación en la "prueba de rotadores de cadera" (p <0,001). Se exponen las posibles relaciones del tono muscular de los rotadores externos de las caderas y el sistema estomatognático, con especial atención en el tejido fascial y sus características morfológicas. A pesar de estas conexiones anatomofisiológicas, no existe una evidencia mayor de una relación importante causa-efecto en esta prueba.

ABSTRACT

RESUMO O objetivo do presente estudo foi analisar a atividade mioelétrica (EMG), o tempo sob tensão (TST) e a projeção dos joelhos no exercício agachamento sem o uso de implementos (SI) e com o uso de physioball (PH) e banda elástica (BE) em diferentes intensidades de esforço. Dez homens realizaram o exercício nos três protocolos com a intensidade de 50 e 100% de 10 RM. A distância entre joelhos no protocolo controle (51,25cm) foi menor quando comparada com o SI 50% (84,38cm; p < 0,001), com o SI 100% (88,80cm; p < 0,001) e com BE 100% (67,41cm; p = 0,014). A distância entre os joelhos também foi menor para os protocolos PH 100% (53,10cm; p < 0,001) e BE 100% (67,41cm; p < 0,001) comparada ao SI 100% (88,80cm). O Vasto Medial Oblíquo (VMO) apresentou maior ativação nos protocolos SI 50% (p = 0,035) e PH 50% (p = 0,028) quando comparados ao protocolo BE 50%. A realização do agachamento com cargas submáximas parece aumentar e diminuir a ativação do VMO quando realizado com PH e BE, respectivamente.


ABSTRACT The objective of the present study was to analyze the myoelectric activity (EMG), the time under tension (TST) and the knee projection in the squat exercise without the use of implements (SI) and with the use of physioball (PH) and elastic band (EB) at different intensities of effort. Ten men performed the exercise in the three protocols with the intensity of 50 and 100% of 10 RM. The distance between knees in the control protocol (51.25 cm) was lower when compared to SI 50% (84.38 cm, p <0.001), with SI 100% (88.80 cm, p <0.001) and with EB 100% (67.41cm, p = 0.014). The distance between the knees was also lower for the protocols PH 100% (53.10cm, p <0.001) and EB 100% (67.41, p <0.001) compared to the SI 100% (88.80 cm) protocols. The Vasto Medial Oblique (VMO) presented greater activation in the SI 50% protocols (p = 0.035) and PH 50% (p = 0.028) when compared to the EB 50% protocol. The accomplishment of squatting with submaximal loads seems to increase and decrease the activation of VMO when performed with physioball and BE, respectively.

ABSTRACT

Abstract Introduction: The impairment of muscle strength and fatigue in leprosy remains a problem that requires careful attention to avoid or minimize its progression, as well as prevention of disabilities and deformities. Objective: To investigate the maximum voluntary contraction and time to muscle fatigue in leprosy patients. Method: A total of 21 leprosy patients and 21 healthy subjects completed the sample. The method used to determine the maximum voluntary contraction (MVC) of the handgrip followed the recommendation of the American Society of Hand Therapists with the use of a hydraulic hand grip dynamometer. The test was performed three times with each hand, with a time interval of 60 seconds between successive trials. The subject was instructed to perform a maximal isometric force against the dynamometer for 5 seconds. The peaks were recorded and used for the fatigue test. For the fatigue test, we recorded the electromyogram of the forearm muscles to offline determine the onset time for the muscle contraction (14 bits, Miograph 2 USB®, Miotec, Brazil). Results: Leprosy patients had lower MVC compared with healthy subjects (p > 0.05), both in the dominant and the non-dominant hands. The time to fatigue in the leprosy and control groups was similar (p < 0.05). We observed that leprosy patients had more contractions than the healthy subjects (22.6 ± 11.8 contractions for the leprosy group vs. 12.3 ± 6.9 contractions for the control group, p > 0.05). Conclusion: Multibacillary leprosy patients lost muscle force without modifying the resistance to fatigue.


Resumo Introdução: O comprometimento da força muscular e a fadiga na hanseníase continuam sendo problemas que requerem cuidadosa atenção para evitar ou minimizar sua progressão, bem como prevenir incapacidades e deformidades. Objetivo: Avaliar a força muscular e o tempo até a fadiga em pacientes com hanseníase Método: Vinte e um pacientes com hanseníase e 21 indivíduos saudáveis completaram a amostra. O método utilizado para determinar a contração voluntária máxima (CVM) da força de preensão palmar seguiu a recomendação da Sociedade Americana de Terapeutas da Mão com o uso de um dinamômetro de preensão manual. O teste foi realizado três vezes em cada mão, com intervalo de tempo de sessenta segundos entre tentativas sucessivas. O sujeito foi instruído a realizar força isométrica máxima contra o dinamômetro durante cinco segundos. Os picos foram registrados e usados para o teste de fadiga. Para o teste de fadiga, registrou-se o eletromiograma dos músculos do antebraço para determinar off-line o tempo de início da contração muscular (14 bits, Miograph 2 USB ® , Miotec, Brasil). Resultados: Os pacientes com hanseníase apresentaram menor CVM em relação aos saudáveis (p < 0,05) nas mãos dominante e não dominante. Não houve diferença no tempo de fadiga entre os grupos hanseníase e controle (p > 0,05). Foi observado que os pacientes com hanseníase tinham mais contrações do que os saudáveis (22,6 ± 11,8 contrações para o grupo com hanseníase vs. 12,3 ± 6,9 para o grupo controle, p < 0,05). Conclusão: Pacientes com hanseníase multibacilar apresentaram perda de força muscular sem modificação da resistência à fadiga.


Resumen Introducción: El compromiso de la fuerza muscular y la fatiga en la lepra sigue siendo un problema que requiere atención cuidadosa para evitar o minimizar su progresión, así como la prevención de incapacidades y deformidades. Objetivo: Evaluar la fuerza muscular y el tiempo hasta la fatiga de pacientes con lepra. Método: Veintiún pacientes con lepra y 21 sujetos sanos completaron la muestra. El método utilizado para determinar la contracción voluntaria máxima (CVM) de la fuerza de asimiento palmar siguió la recomendación de la Sociedad Americana de Terapeutas de la Mano con el uso de un dinamómetro de asimiento manual. La prueba se realizó tres veces con cada mano, con un intervalo de tiempo de 60 segundos entre intentos sucesivos. El sujeto fue instruido a realizar una fuerza isométrica máxima contra el dinamómetro durante 5 segundos. Los picos se registraron y se utilizaron para la prueba de fatiga. Para la prueba de fatiga, registramos el electromiograma de los músculos del antebrazo para determinar fuera de línea el tiempo de inicio de la contracción muscular (14 bits, Miograph 2 USB ® , Miotec, Brasil). Resultados: Los pacientes con lepra presentaron menor CVM con relación a los sanos (p < 0,05) en las manos dominante y no dominante. No hubo diferencia en el tiempo de fatiga entre los grupos de lepra y control (p > 0,05). Se observó que los pacientes con lepra tenían más contracciones que los sanos (22,6 ± 11,8 contracciones para el grupo con hanseniasis frente a 12,3 ± 6,9 para el grupo control, p < 0,05). Conclusión: Pacientes con hanseniasis multibacilar presentaron pérdida de fuerza muscular sin modificación de la resistencia a la fatiga.

ABSTRACT

Objective: To evaluate the short-term effect of two hydrokinesiotherapy protocols on muscle tone and stress levels in children with SCZ. Method: A crossover, randomized, blinded study with children with microcephaly/SCZ between 3-36 months of age. Was evaluated by the Modified Tardieu Scale(EMT), analyzing the degree of muscle tone and the range of articular movement(ROM); the level of stress, through a visual analogue scale of faces ranging from a state without stress(1) to intense stress(4). Two hydrocinesotherapy protocols(PI and PII) were applied in a restricted aquatic environment, for 15 minutes with water temperature at 37ºC. Results: Twelve children participated in the study (mean age in months: 23.9+3.97), 58.7% female. After PI, we observed a reduction in the degree of tone of the extensor muscles of the elbow(p = 0.03) and knee(p = 0.04); in PII, there were no significant changes in the degree of tone. There were no significant changes in the level of stress in PI and PII, however 83.3% were without stress or mild stress before the interventions. Conclusions: Protocol I reduced the degree of muscle tone in the short term when compared to PII. It is emphasized that the protocols applied are of low cost, and can be a viable non-pharmacological technique option in the therapeutic follow-up of these children. It should be noted that the physiotherapist's experience should guide the choice of the appropriate protocol for the therapeutic objective of each child and the advantage of being a technique easily replicable in a therapeutic and home environment.

ABSTRACT

ABSTRACT BACKGROUND: Digital rectal examination (DRE) is part of the physical examination, is also essential for the colorectal surgeon evaluation. A good DRE offers precious information related to the patient's complaints, which will help in decision making. It is simple, quick and minimally invasive. In many centers around the world, the DRE is still the only method to evaluate the anal sphincter prior to patient's management. On the other hand, anorectal manometry (ARM) is the main method for objective functional evaluation of anal sphincter pressures. The discrepancy of DRE depending on the examiner to determine sphincter tonus in comparison to ARM motivated this study. OBJECTIVE: To compare the DRE performed by proficient and non-experienced examiners to sphincter pressure parameters obtained at ARM, depending on examiners expertise. METHODS: Thirty-six consecutive patients with complaints of fecal incontinence or chronic constipation, from the anorectal physiology clinic of the University of São Paulo School of Medicine, were prospectively included. Each patient underwent ARM and DRE performed by two senior colorectal surgeons and one junior colorectal surgeon prior to the ARM. Patient's history was blinded for the examiner's knowledge, also the impressions of each examiner were blinded from the others. For the DRE rest and squeeze pressures were classified by an objective scale (DRE scoring system) that was compared to the parameters of the ARM for the analysis. The results obtained at the ARM were compared to the DRE performed by the seniors and the junior colorectal surgeons. STATISTICAL ANALYSIS: Descriptive analysis was performed for all parameters. For the rest and squeeze pressures the Gamma index was used for the comparison between the DRE and ARM, which varied from 0 to 1. The closer to 1 the better was the agreement. RESULTS: The mean age was 48 years old and 55.5% of patients were female. The agreement of rest anal pressures between the ARM and the DRE performed by the senior proficient examiners was 0.7 (CI 95%; 0.32-1.0), while for the junior non-experienced examiner was 0.52 (CI 95%; 0.09-0.96). The agreement of squeeze pressures was 0.96 (CI 95%; 0.87-1.0) for the seniors and 0.52 (CI 95%; 0.16-0.89) for the junior examiner. CONCLUSION: More experienced colorectal surgeons used to DRE had a more significant agreement with the ARM, thereafter would have more appropriate therapeutic management to patients with sphincter functional problems. ARM, therefore, persists as an important exam to objectively evaluate the sphincter complex, justifying its utility in the clinical practice.


RESUMO CONTEXTO: Exame anorretal digital (EAD) faz parte do exame físico, também é essencial para a avaliação do cirurgião colorretal. Um bom EAD oferece informações preciosas relacionadas às queixas do paciente, que auxiliam na tomada de decisões. Sua realização é simples, rápida e minimamente invasiva. Em diversos centros ao redor do mundo, o toque retal ainda é o único método para avaliar o esfíncter anal antes do tratamento. Por outro lado, a manometria anorretal (MAR) é o principal método para avaliação funcional objetiva das pressões esfincterianas. A discrepância entre o EAD, dependendo do examinador para determinar o tônus esfincteriano em comparação à MAR motivou este estudo. OBJETIVO: Comparar o EAD com os parâmetros de pressão esfincteriana obtidos na MAR, dependendo da experiência dos examinadores. MÉTODOS: Trinta e seis pacientes consecutivos com queixas de incontinência fecal ou constipação crônica, do ambulatório de Fisiologia Anorretal da Faculdade de Medicina da Universidade de São Paulo, foram prospectivamente incluídos. Cada paciente foi submetido a MAR e EAD realizados por dois cirurgiões colorretais seniores e um júnior antes da MAR. A história dos pacientes propositalmente omitida dos examinadores, e os resultados de cada examinador foram cegos dos demais. Para o EAD, as pressões de repouso e contração foram classificadas por uma escala objetiva (EAD Scoring System), realizada pelos examinadores seniores e pelo júnior em todos os pacientes, que foi comparada com os parâmetros da MAR para a análise. ANÁLISE ESTATÍSTICA: A análise descritiva foi feita para todos os parâmetros. Para as pressões de repouso e contração, o índice Gamma foi utilizado para a comparação entre o EAD e a MAR, que variou de 0 a 1. Quanto mais próximo de 1 melhor a concordância entre os dois métodos de avaliação. RESULTADOS: A idade média foi de 48 anos e 55,5% dos pacientes eram do sexo feminino. A concordância das pressões anais de repouso entre a MAR e o EAD realizadas pelos examinadores seniores, proficientes, foi de 0,7 (IC 95%; 0,32-1,0), enquanto para o examinador júnior, menos experiente, foi de 0,52 (IC95%; 0,09-0,96). A concordância das pressões de contração foi de 0,96 (IC 95%; 0,87-1,0) para os examinadores seniores e de 0,52 (IC 95%; 0,16-0,89) para o júnior. CONCLUSÃO: Cirurgiões colorretais mais experientes, o EAD teve concordância mais significativa com a MAR, o que poderia levar a um manejo terapêutico mais adequado aos pacientes portadores de doença anorretais funcionais. A manometria anorretal permanece, portanto, como método de avaliação objetiva da função esfincteriana.

ABSTRACT

Stiff-person syndrome is a rare disorder, and the natural history of the syndrome has not been completely ascertained. The symptoms range from mild to severe and can progress over time: the final result can be significant disability. However, this syndrome is often misdiagnosed due to a lack of understanding of the clinical manifestations. We report the case of a patient who presented with slowly progressing gait disturbance and lower extremity pain and was later diagnosed as suffering from stiff-person syndrome. The patient experienced symptomatic improvement after the administration of benzodiazepines. No recurrence of symptoms has been reported. If the characteristic clinical features and electromyography findings of the syndrome are accurately interpreted, diagnosis of patients with abnormal muscle tension can be effectively done.

ABSTRACT

Functional dysphonia (FD) is a disease entity which includes various voice disorders in the absence of structural or neurologic laryngeal pathology. Muscle tension dysphonia (MTD), psychogenic dysphonia are representative FD with completely different pathogenesis. Therefore there is no standard treatment modality for FD, the first step of treatment of FD is differentiating patient's voice symptoms from other organic voice disorders and other functional voice problems. MTD is a functional voice disorder caused by hyperfunction of intrinsic and extrinsic laryngeal musculature. Symptoms include increased vocal effort, roughness, fatigue and odynophonia. First line for MTD is indirect or direct voice therapy. Unfortunately, many patients with MTD improve with voice therapy alone. For these patients, various modalities tried; lidocaine application, surgical excision of the false vocal folds, and botulinum toxin injection, etc. Botulinum toxin injections are widely used in the field of otolaryngology, especially for spasmodic dysphonia. However, its use in FD or MTD has only been described in few case reports. The aim of this lecture is to evaluate the feasibility of botulinum toxin injection for FD, especially MTD.

ABSTRACT

BACKGROUND AND OBJECTIVES: The goal of this study is to present a strategy for improving the self-regulation (SR) ability and facilitating the change of vocal behavior by applying voice therapy using the SR concept to the patients with vocal cord nodule and muscle tension dysphonia. MATERIALS AND METHOD: The subjects were 80 patients and 80 patients who were diagnosed with muscle tension dysphonia and vocal nodules. As a control group, the results were compared among patients with the same dysphonia without using SR strategies. The concept of SR before voice therapy was explained to the patients, and the treatment was divided into three stages according to the goal of voice therapy. The treatment stages consist of 1) skill acquisition, 2) habit formation, and 3) habit changes. voice therapy was performed by applying SR strategies such as goal implementation intentions and a less routine behavior. Patient's dropout rates were measured to compare the adherence of voice therapy. RESULTS: Significant improvement was seen in all groups receiving voice therapy. However, in the group using the SR strategy, the voice analysis results showed a relatively low dropout rate of voice therapy. In the generalization confirmation stage, patients who applied SR concept showed better results. SR strategy did no longer be necessary to maintain newly adopted vocal behavior. CONCLUSION: The results of this study show that SR is one of the cognitive factors that can have a significant impact on the outcome of voice therapy, and also has a positive impact on the acquisition and generalization of new skills. A better understanding of SR and the development of therapeutic strategies using it will play an important role in solving voice problems in clinical settings.

ABSTRACT

Solitary neurofibroma of the glottis is extremely rare and accounts for only 0.1–1.5% of benign laryngeal tumors. Aryepiglottic fold is the most frequent involved site followed by arytenoids and ventricular folds. There have been few reports of neurofibroma of the true vocal cord. We report a case of neurofibroma which was deeply embedded in the vocal cord and misdiagnosed as muscle tension dysphonia with a review of literatures.

ABSTRACT

Abstract An HTLV-1-infected patient can develop paraparesis that limits their movements. Rehabilitation techniques could improve the motor abilities of these patients. The present study investigates five cases of physical therapy intervention in HTLV-1 patients to evaluate the influence of functional rehabilitation on the tonus and range of motion (ROM) of HTLV-1 patients with spasticity. The patients had a gain of ROM, especially in the lower limb, and reduction in hypertonia/spasticity after functional treatment. The reduction in hypertonia increased the ROM. Thus, functional methods may be valuable for the rehabilitation of HTLV-1 patients with neurological damage.

ABSTRACT

Abstract Objectives: The esthetic and functional results of orthognathic surgery of severe dentofacial deformities are predictable, however there are differences regarding the effects on stomatognathic system. The aim was to investigate the effects of orofacial myofunctional therapy (OMT) on the masticatory function in individuals with dentofacial deformity submitted to orthognathic surgery (OGS). Material and Methods: Forty-eight individuals (18-40 years) were evaluated, 14 undergoing OMT (treated group-TG), 10 without this treatment (untreated group-UTG) and 24 in a control group with normal occlusion; for clinical aspects the data of an individual was missed (n=46). Chewing was performed using the Expanded protocol of orofacial myofunctional evaluation with scores (OMES-E). Muscle tone and mobility were also analyzed before (P0), three (P1) and six months (P2) after OGS. Surface electromyography of the masseter and temporalis muscles was performed, considering the parameters amplitude and duration of act and cycle, and the number of masticatory cycles. The OMT consisted of ten therapeutic sessions along the postoperative period. The results were compared using parametric and non-parametric tests. Results: TG showed higher scores in P1 and P2 than P0; for the masticatory type the scores in P2 were significantly higher than P0. In addition, the proportion of individuals with adequate tone of lower lip and adequate tongue mobility for TG increased significantly from P1 and P2 in relation to P0. The EMG results showed a decrease in act and cycle duration in P2 in relation to P0 and P1 for the TG; furthermore the values were close to controls. An increase in the number of cycles from P0 to P2 was also observed, indicating faster chewing, which may be attributed to an improvement of balanced occlusion associated with OMT. Conclusion: There were positive effects of OMT on the clinical and electromyography aspects of chewing in individual submitted to orthognathic surgery.

ABSTRACT

OBJECTIVE@#To compare the clinical curative effect of muscle tension staged acupuncture and conventional acupuncture in the treatment of stroke hemiplegia.@*METHODS@#Sixty-two patients with stroke hemiplegia were randomly divided into an observation group and a control group, 31 cases in each one. In the observation group, the muscle tension staged acupuncture was given, the six stages of Brunnstrom were classified as relaxation period and spasmodic period. The (consciousness-restoring resuscitation) combined with the hand and foot meridian acupuncture were applied at Shuigou (GV 26), Jianyu (LI 15), Quchi (LI 11), Shousanli (LI 10), Hegu (LI 4), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Jiexi (ST 41) during relaxation period; mainly by hand and foot meridian and meridian, the acupoints were Jianliao (TE 14), Tianjing (TE 10), Waiguan (TE 5), Yangchi (TE 4), Houxi (SI 3), Huantiao (GB 30), Yanglingquan (GB 34), Chengshan (BL 57), Xuanzhong (GB 39), Shenmai (BL 62), Qiuxu (GB 40) during spasmodic period. In the control group, referring to 's , mainly by hand meridian, the governor vessel and foot meridian, phasing was not considered in the acupuncture treatment plan. Both groups were treated one time a day for 4 weeks. The neurological deficit scores were observed before and after treatment of the two groups and the efficacy was evaluated.@*RESULTS@#There was one case dropped in each group. After treatment, the neurological deficit scores of the two groups was lower than those before treatment (both <0.05), and the observation group was lower than the control group (<0.05). The cured and markedly effective rate was 66.7% (20/30) in the observation group, which was higher than 36.7% (11/30) in the control group, the difference between the two groups was statistically significant (<0.05).@*CONCLUSION@#The muscle tension staged acupuncture is better than the conventional acupuncture for the treatment of stroke hemiplegia.

ABSTRACT

This study suggested a new EMG-signal-based evaluation method for knee rehabilitation that provides not only fragmentary information like muscle power but also in-depth information like muscle fatigue in the field of rehabilitation which it has not been applied to. In our experiment, nine healthy subjects performed straight leg raise exercises which are widely performed for knee rehabilitation. During the exercises, we recorded the joint angle of the leg andEMGsignals from four prime movers of the leg: rectus femoris (RFM), vastus lateralis, vastus medialis, and biceps femoris (BFLH). We extracted two parameters to estimate muscle fatigue from the EMG signals, the zero-crossing rate (ZCR) and amplitude of muscle tension (AMT) that can quantitatively assess muscle fatigue from EMG signals. We found a decrease in the ZCR for the RFM and the BFLH in the muscle fatigue condition for most of the subjects. Also, we found increases in theAMT for the RFM and the BFLH. Based on the results, we quantitatively confirmed that in the state of muscle fatigue, the ZCR shows a decreasing trend whereas theAMT shows an increasing trend. Our results show that both the ZCR and AMT are useful parameters for characterizing the EMG signals in the muscle fatigue condition. In addition, our proposed methods are expected to be useful for developing a navigation system for knee rehabilitation exercises by evaluating the two parameters in two-dimensional parameter space.
