CONTEXTUALIZACAO: Na reabilitacao, a imobilizacao em alongamento do musculo esqueletico e realizada como contramedida para reverter efeitos de encurtamento muscular severo e em eventos pos-cirurgicos. Acredita-se que o retorno as atividades funcionais normais estimule mecanotransdutores capazes de reorganizar a citoarquitetura normal muscular, porem a descricao das alteracoes histopatologicas relacionadas a esses procedimentos sao escassas na literatura. OBJETIVOS: Avaliar e quantificar anomalias histologicas induzidas pela imobilizacao em alongamento do musculo EDL (Extensor Digitorum Longus) e confronta-las com a livre movimentacao do animal apos esse procedimento. METODOS: Foram utilizadas 18 ratas Wistar, distribuidas nos grupos: controle (GC); imobilizadas em flexao plantar (EDL em posicao alongada) por 14 dias (GI); imobilizadas por 14 dias e liberadas por dez dias (GIL). Fragmentos do EDL foram congelados, seccionados e processados com reacoes imuno-histoquimica para colagenos I e III e histoquimica para Adenosina Trifosfatase Miofibrilar e Hematoxilina-Eosina. RESULTADOS: Os animais do GI apresentaram discreto aumento da expressao de colageno I e de fibras em processo degenerativo/necrotico, reducao da proporcao de fibras tipo (FT) 2A e do diâmetro menor de todos os tipos de fibras, quando comparados com os animais do GC. Para o GIL, observou-se retorno da quantidade de colageno I as condicoes controle, alem de reducao na proporcao de FT2D, aumento do numero de nucleos centralizados e do diâmetro menor das fibras quando comparadas com o GI, porem a expressao de FT2B e FT2D nao atingiu os valores de referencia. CONCLUSOES: Os dados apresentados mostram que a retomada da funcao durante dez dias foi parcialmente eficiente na recuperacao das caracteristicas do musculo EDL apos o periodo de imobilizacao e que, se extrapolados os dados a clinica fisioterapeutica, a adocao de procedimentos orientados as disfuncoes primarias do musculo pode favorecer a resposta morfofuncional do segmento e o seu integro restabelecimento.

BACKGROUND: The applicability of gait analysis has been implemented with the introduction of the principal component analysis (PCA), a statistical data reduction technique that allows the comparison of the whole cycle between groups of individuals. OBJECTIVES: Applying PCA, to compare the kinematics of the knee joint during gait, in the frontal and sagittal planes, between a group of elderly women with and without diagnosis in the initial and moderate stages of Osteoarthritis (OA). METHODS: A total of 38 elderly women (69.6±8.1 years) with knee OA and 40 asymptomatic (70.3±7.7 years) participated on this study. The kinematics was obtained using the Qualisys Pro-reflex system. RESULTS: The OA group showed decreased gait velocity and stride length (p<0.05) and was characterized with higher WOMAC pain score. In the frontal plane, the between-group differences of the components were not significant. In the sagittal plane, three principal components explained 99.7% of the data variance. Discriminant analysis indicated that component 2 and 3 could classify correctly 71.8% of the individuals. However, CP3, which captures the difference in the flexion knee angle magnitude during gait, was the variable with higher discrimination power between groups. CONCLUSIONS: PCA is an effective multivariate statistical technique to analyse the kinematic gait waveform during the gait cycle. The smaller knee flexion angle in the OA group was appointed as a discriminatory factor between groups, therefore, it should be considered in the physical therapy evaluation and treatment of elderly women with knee OA.

BACKGROUND: The use of surface electromyography (SEMG) has been considered a tool for quantitative assessment of patellofemoral pain syndrome (PFPS). Conservative treatments aim to improve patellar alignment, and electrical stimulation of the vastus medialis obliquus (VMO) muscle has been considered effective because it is selective and does not cause joint irritation. OBJECTIVE: This study aims to investigate the efficiency of a muscle strengthening program with electrical stimulation of the VMO muscle in PFPS by SEMG. METHODS: A group of ten young women (age: 23.1±4.9 years; body mass: 66.8±14.0 kg; height: 1.63±6.9 cm; BMI: 25.1±5.6 kg/m2) with unilateral PFPS participated in the study. They performed the functional test of stair stepping to capture the electromyographic (EMG) activity of the VMO and vastus lateralis (VL) muscles, before and after a program of electrical stimulation of the VMO muscle. The electrical stimulation was performed three times per week for six weeks. For analysis between the VMO and VL muscles, we considered the variables: ratio of time of onset to peak of activation, ratio of the integrals of the signals (t-test for dependent samples), and difference between onsets of activation (Wilcoxon test), with significance level of p<0.05. RESULTS: The results only showed change in behavior in the EMG signal for the ratio of the integrals of the signals, indicating that changes occurred in the force-generating capacity of the muscle after the training. CONCLUSION: The use of electrical stimulation should be considered to complement the conservative therapeutic approach in patients with PFPS, and the analysis of the ratio of the integrals of the SEMG signals should be considered as an instrument of evaluation.

CONTEXTUALIZACAO: A esteira motorizada desencadeia passadas em bebes similares ao andar. Entretanto, os efeitos da velocidade da esteira nas caracteristicas das passadas desencadeadas por ela ainda sao desconhecidos. OBJETIVO: Examinar o efeito da velocidade da esteira em passadas desencadeadas em bebes. METODOS: Seis bebes com desenvolvimento tipico, com idades entre 11 e 13 meses, iniciando o andar independente, foram filmados andando na esteira em quatro velocidades (0,10; 0,16; 0,22 e 0,28 m/s), com marcas passivas posicionadas em suas principais articulacoes (ombro, quadril, joelho e tornozelo). As imagens foram digitalizadas e analisadas com os softwares Ariel Performance Analysis System, Matlab e SPSS (Statistical Package for Social Sciences, v.10). As variaveis analisadas foram as caracteristicas descritivas, temporais, coordenativas e angulares das passadas desencadeadas pela esteira nas quatro velocidades. RESULTADOS: Em 0,22 e 0,28 m/s, ocorre aumento da velocidade e duracao da passada, alem de uma menor duracao da fase de apoio (FA) na velocidade de 0,22 m/s. Nas velocidades de 0,22 e 0,28 m/s,observa-se aumento da amplitude articular do joelho. CONCLUSOES: As velocidades moderadas e rapidas parecem ser as mais indicadas para desencadear passadas em bebes que estao iniciando o andar independente, sendo ainda que a velocidade de 0,22 m/s parece ser a mais apropriada.

OBJECTIVES: To compare and to analyze whether the values of rapid shallow breathing index (RSBI) determined by a ventilator display and a digital ventilometer were correlated. METHODS: Twenty-two adult patients (17 males and 5 females) in the postoperative period of cardiac surgery and in mechanical ventilation were studied. Prior to the data collection, each patient was evaluated, received physical therapy, in order to promote bronchial hygiene and pulmonary reexpansion, and was positioned in elevated dorsal recumbent at 45o. After these procedures, minute ventilation (MV) and respiratory rate (RR) obtained from mechanical ventilator display and digital ventilometer were recorded. The RSBI was calculated by the ratio of RR and tidal volume (VT). Paired t-test was used to compare related variables. The intra-class correlation coefficients (ICCs) were used to measure the reproducibility of the scores. RESULTS: A significant difference was found between the RSBI obtained from the ventilator and by the digital ventilometer (p=0.011). A high agreement for the RSBI (ICC=0.86), for the RR (ICC=0.80) for the VT (ICC=0.79) and a moderate agreement for the MV (ICC=0.74) were observed. The p-value was <0.05 for all variables. CONCLUSIONS: There were a significant agreement between the RSBI obtained from the ventilator display and the digital ventilometer.

OBJECTIVES: To translate and culturally adapt the Shoulder Pain and Disability Index (SPADI) into Brazilian-Portuguese and to assess its reliability. METHODS: The first step was the translation, synthesis, back-translation, revision by the committee, pre-testing and evaluation of documents by the committee and the author of the SPADI. The revised version by the committee was applied to 90 subjects with shoulder dysfunction, aged over 18 years from different education and sociocultural levels. The items misunderstood by 20% or more of patients were reformulated and reapplied until they reach values lower than 20%. The second stage consisted of two applications of SPADI to 32 patients with shoulder dysfunction in a interval ranging from 2 to 7 days. The data from the translation were analyzed descriptively, the test-retest reliability by Intraclass Correlation Coefficient (ICC) and the internal consistency by Cronbach's Alpha. RESULTS: Some expressions have been adapted to the Brazilian population and the items in the pain and disability subscales were changed for an easier reading in Portuguese Language. The pre-test revealed a need to change only one item of the pain domain and to administer the questionnaire by interview, since it was repeated three times and in the first two applications with self-reported questionnaire the patients had not been reporting their symptoms with regards to the past week and also they have not been properly used the item "Not Applicable". The test-retest reliability ranged from 0.90 to 0.94 and the internal consistency ranged from 0.87 to 0.89. CONCLUSION: After the translation and cultural adaptation, it was obtained a reliable version of SPADI-Brazil.

BACKGROUND: Despite of the widepread use of Pilates in Physical Therapy, there are few studies that have assessed the muscle electrical activation during Pilates exercises. OBJECTIVE: Verify the influence of different spring adjustments and individual positions on the electrical activation of multifidus (MU) and oblique external (OE) muscles during hip flexion-extension (HFE) exercise on the Cadillac. METHODS: Eight women practicing Pilates exercises for at least six months performed 10 repetitions of HFE in the following situations: Lower Spring, spring fixed at 30 cm in relation to level which the individuals were positioned. Higher Spring, spring fixed at 90 cm in relation to level which the individuals were positioned. Near Position, distance of 10 cm from the fixed spring. Distant Position, distance of 30 cm from the fixed spring. Kinematic and eletromyographic data (EMG) were collected simultaneously and the MU and OE muscles were monitored. Each movement of HFE was splitted in two phases (extension and flexion). The EMG signal was calculated and normalized using the maximal voluntary contraction (MVC). The Wilcoxon test was used to investigate differences between the situations (p<0.05). RESULTS: MU muscle presented muscle activation values ranging from 10 to 20 % MVC, and the highest muscle activation in the lower spring and in the near position. OE muscles presented muscle activation values ranging from 20 to 45% MVC, and the highest values in the higher spring and in the distant position. CONCLUSION: MU and OE muscles presented a distinct electrical activation during different available spring adjustments and individual positions.

Each movement of HFE was splitted in two phases (extension and flexion). The EMG signal was calculated and normalized using the maximal voluntary contraction (MVC). The Wilcoxon test was used to investigate differences between the situations (p<0.05). RESULTS: MU muscle presented muscle activation values ranging from 10 to 20 % MVC, and the highest muscle activation in the lower spring and in the near position. OE muscles presented muscle activation values ranging from 20 to 45% MVC, and the highest values in the higher spring and in the distant position. CONCLUSION: MU and OE muscles presented a distinct electrical activation during different available spring adjustments and individual positions.","PeriodicalId":21195,"journal":{"name":"Revista Brasileira De Fisioterapia","volume":"14 1","pages":"510-517"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78564506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BACKGROUND: Due to the complexity of clinical symptoms of cerebral palsy and the difficulties in classifying it based upon the motor types and the topography of the body distribution only, Canadian researchers have proposed the Gross Motor Function Classification System (GMFCS). Although this classification system has been largely used in Brazil, it has not been cross culturally adapted yet. OBJECTIVES: To perform the cross adaptation of the Gross Motor Function Classification System for the Cerebral Palsy (GMFCS) into Brazilian-Portuguese and to verify the reliability among observers of the adapted instrument in Brazilian children. METHODS: This study was performed in two stages; the first stage was related to the process of cross-cultural adaptation and the second stage tested the instrument. Translation, back-translation, semantic and content analysis, back-translation of the final version and the approval of the authors were used for the cross-cultural adaptation. The test of the instrument was performed in 40 children with cerebral palsy, who were evaluated by two raters to verify the reliability among the observers. RESULTS: The results showed that the stages of translation and back-translation did not present any difficulties and the semantic and conceptual equivalence was achieved. The reliability among the observers showed that the evaluations do not differ and that there is an excellent correlation and internal consistency of the construct with an ICC of 0.945 (95% CI 0.861 to 0.979) and a Cronbach a of 0.972. CONCLUSIONS: The final version of the GMFCS showed good potential of applicability for undergraduate students and professionals of the neuropediatric area.
背景:由于脑瘫临床症状的复杂性和仅根据运动类型和身体分布地形进行分类的困难，加拿大研究人员提出了大运动功能分类系统(GMFCS)。虽然这个分类系统在巴西已经被广泛使用，但它还没有被跨文化适应。目的:对脑瘫大运动功能分类系统(GMFCS)进行巴西-葡萄牙语交叉适应，并验证巴西儿童中适应工具的观察者之间的可靠性。方法:本研究分为两个阶段;第一阶段是关于跨文化适应的过程，第二阶段是对乐器的测试。跨文化改编的过程包括翻译、反译、语义和内容分析、最终版本的反译和作者的审定。该仪器在40例脑瘫患儿中进行了测试，由两名评分员对其进行评估，以验证观察者之间的可靠性。结果:翻译和反译阶段均无困难，语义和概念均达到了对等。观察者之间的信度表明，评估没有差异，结构具有极好的相关性和内部一致性，ICC为0.945 (95% CI 0.861至0.979)，Cronbach a为0.972。结论:最终版GMFCS在神经儿科本科及专业人员中具有良好的应用潜力。

CONTEXTUALIZACAO: Os instrumentos de avaliacao funcional utilizados para pacientes com distrofia muscular de Duchenne (DMD), citados na literatura, sao limitados e escassos, dificultando a tomada de decisao clinica fisioterapeutica. OBJETIVOS: Descrever o processo de criacao de uma escala de avaliacao funcional do subir e do descer escadas, especifica para criancas com diagnostico de DMD, e examinar sua confiabilidade inter e intraexaminadores. METODOS: A construcao da escala seguiu cinco etapas, a saber, elaboracao de um roteiro para observacao dirigida com base na literatura; observacao do subir e do descer em 120 registros filmados de 30 criancas com DMD (5 a 11 anos); elaboracao da escala, considerando o grau crescente de dificuldade de execucao dos movimentos; criacao do manual de preenchimento e submissao da escala e do manual a 10 examinadores, seguida de reajustes para criacao da versao final. A confiabilidade foi testada pelo pesquisador (repetibilidade) e dois examinadores independentes (reprodutibilidade). Utilizou-se o Indice de Correlacao Intra-Classe (ICC) e a Correlacao de Kappa Ponderado. RESULTADOS: A escala elaborada abrange cinco fases para o subir e quatro fases para o descer escadas. Encontrou-se excelente confiabilidade intra/interexaminadores, com valores da Correlacao de Kappa Ponderado > 0,78 em todas as fases e ICCs > 0,89, com p<0,05 entre todos os escores. CONCLUSAO: A escala proposta mostrou excelente repetibilidade e reprodutibilidade, sendo necessaria a continuidade do estudo com os objetivos de avaliar sua acuracia e validade e de construir uma ferramenta digital para otimizar a coleta de dados.

CONTEXTUALIZACAO: A forca muscular respiratoria e influenciada pelo envelhecimento. OBJETIVOS: Avaliar, em uma populacao de idosos saudaveis, a influencia da atividade fisica e do nivel funcional sobre parâmetros da funcao pulmonar, sobre a forca da musculatura respiratoria e sobre a tosse. METODOS: Estudo observacional em que foram incluidos 61 idosos com idade igual ou superior a 60 anos (72,3±7,2 anos), com espirometria normal. Foram avaliados: pressao inspiratoria maxima (PImax), pressao expiratoria maxima (PEmax), pico de fluxo expiratorio (PFE), pico de fluxo da tosse (PFT) e perfil de atividade humana (PAH). Os idosos foram divididos em dois grupos (ativo e moderadamente ativo) classificados conforme o PAH. Utilizou-se o teste t de Student nas analises univariadas e foram desenvolvidos modelos de regressao linear nas analises multivariadas. RESULTADOS: Os idosos ativos apresentaram, em media, 13,5 cmH2O a mais no valor da PEmax (88±21,4 cmH2O) e 16,2 cmH2O na PImax (76±17,7 cmH2O), ocorrendo queda, em media, de 1 cmH2O a cada ano nessas variaveis. O PFE e o PFT foram maiores nos idosos do sexo masculino (p<0,001 para ambos) e nos ativos (p=0,046 e p=0,004; respectivamente). Observou-se correlacao positiva entre PAH e as seguintes variaveis: PEmax, PImax e PFT (r=0,527, p<0,001; r=0,498, p<0,001 e r=0,365, p=0,004 respectivamente). CONCLUSOES: O estilo de vida mais ativo pode influenciar de forma positiva, relacionando-se com maior forca da musculatura respiratoria e valores do PFT. O aumento da idade esta relacionado com a reducao da forca muscular inspiratoria e expiratoria. As mulheres apresentaram menor PEmax.
