ABSTRACT

BACKGROUND: The literature emphasizes the need for studies to provide reference values and equations able to predict respiratory muscle strength of Brazilian subjects at different ages and from different regions of Brazil. OBJECTIVES: To develop prediction equations for maximal respiratory pressures (MRP) of Brazilian adolescents. METHOD: In total, 182 healthy adolescents (98 boys and 84 girls) aged between 12 and 18 years, enrolled in public and private schools in the city of Natal-RN, were evaluated using an MVD300 digital manometer (Globalmed®) according to a standardized protocol. Statistical analysis was performed using SPSS Statistics 17.0 software, with a significance level of 5%. Data normality was verified using the Kolmogorov-Smirnov test, and descriptive analysis results were expressed as the mean and standard deviation. To verify the correlation between the MRP and the independent variables (age, weight, height and sex), the Pearson correlation test was used. To obtain the prediction equations, stepwise multiple linear regression was used. RESULTS: The variables height, weight and sex were correlated to MRP. However, weight and sex explained part of the variability of MRP, and the regression analysis in this study indicated that these variables contributed significantly in predicting maximal inspiratory pressure, and only sex contributed significantly to maximal expiratory pressure. CONCLUSION: This study provides reference values and two models of prediction equations for maximal inspiratory and expiratory pressures and sets the necessary normal lower limits for the assessment of the respiratory muscle strength of Brazilian adolescents. .

ABSTRACT

Few studies have addressed early cerebrovascular lethality in Brazil. OBJECTIVE: To evaluate 10 and 28-day stroke case-fatality rates in three hospitals in three Brazilian cities. METHODS: We described the stroke registries in São Paulo, João Pessoa, and Natal. RESULTS: Out of a total of 962 first-ever events (mean age, 68.1 years-old; 53% men), 83.6% (804 cases) were classified as ischemic and 16.4% (158) as hemorrhagic stroke. Overall, the case-fatality rates and 95% confidence intervals (95%CI) for hemorrhagic stroke events were higher than for ischemic events, both at 10 (12.3%; 95%CI 7.2-17.4 versus 7.0%; 95%CI 5.3-8.8) and at 28 days (19.8%; 95%CI 13.6-26.0 versus 11.1%; 95%CI 8.9-13.3). CONCLUSIONS: We did not find any substantial differences in early case-fatality rates according to stroke subtypes, when comparing the three centers.


Poucos estudos abordaram a letalidade cerebrovascular precoce no Brasil. OBJETIVO: Avaliar taxas de letalidade por acidente vascular cerebral (AVC) em 10 e 28 dias após evento em três hospitais em três cidades brasileiras. MÉTODOS: Foram descritos os registros de AVC em São Paulo, João Pessoa e Natal. RESULTADOS: De um total de 962 primeiros eventos (idade média de 68,1 anos; 53% homens), 83,6% (804 casos) foram classificados como AVC isquêmico e 16,4% (158) como hemorrágico. As taxas de letalidade e intervalos de confiança de 95% (IC95%) para eventos de AVC hemorrágico foram maiores que para os isquêmicos em: 10 (12,3%; IC95% 7,2-17,4 versus 7,0%; IC95% 5,3-8,8) e 28 dias (19,8%; IC95% 13,6-26,0 versus 11,1%; IC95% 8,9-13,3). CONCLUSÕES: Não foram encontradas diferenças substanciais nas taxas de letalidade precoce por subtipo de AVC ao comparar os três centros estudados.

ABSTRACT

CONTEXTUALIZAÇÃO: A Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) precisa ser empregada amplamente na pesquisa e prática clínica, mas há escassez de trabalhos que vinculem sua utilização a instrumentos de avaliação utilizados na fisioterapia. OBJETIVO: Comparar os instrumentos de avaliação do sono, cognição e função com a CIF em pacientes com AVE. MÉTODOS: Participaram 12 pacientes (seis mulheres), com idade média de 55,4 (±6,2) anos e tempo de recuperação de sete a 36 meses. Os pacientes foram avaliados pelo Índice de Qualidade do Sono de Pittsburgh (IQSP), Miniexame do Estado Mental (MEEM) e Índice de Barthel (IB). A comparação da frequência das categorias registradas da CIF com os itens dos instrumentos foi realizada por meio do teste de Fisher e teste do qui-quadrado. A concordância das categorias registradas por dois avaliadores foi analisada pelo Índice de Kappa. RESULTADOS: Na análise do IQSP, encontrou-se um escore médio de 5,0 (±3,0); para o MEEM, de 22,5 (±3,4) e para o IB, de 74,6 (±17,2). Na CIF, as alterações identificadas nos instrumentos anteriores foram registradas em 46 categorias, sendo a maior parte no componente "Funções do Corpo", seguido de "Atividades e Participação". Encontrou-se uma concordância interavaliador de 0,87 para o IQSP (substancial), de 0,44 para o MEEM (moderada) e de 0,39 para o IB (justa). CONCLUSÕES: Os resultados indicam que as concordâncias de cada instrumento foram muito diferentes, sugerindo a necessidade de maior utilização desses instrumentos na prática fisioterapêutica, a fim de otimizar a formulação e padronização do diagnóstico fisioterapêutico.


BACKGROUND: The International Classification of Functioning, Disability and Health (ICF) should be widely used in research and clinical practice, but there are few studies that do so with the evaluation instruments used in physical therapy. OBJECTIVE: To compare instruments that evaluate sleep, cognition and function in stroke patients according to the ICF. METHODS: Twelve patients (6 women) with a mean age of 55.4 (±6.2) years and a recovery time from 7 to 36 months took part in the study. Patients were evaluated using the Pittsburgh Sleep Quality Index (PSQI), the Mini-Mental State Examination (MMSE) and Barthel Index (BI). A frequency comparison of ICF categories and those of the above-mentioned instruments was performed using Fisher's exact test and chi-square. Agreement regarding the categories was recorded by two evaluators and assessed with the Kappa index. RESULTS: Mean scores of 5.0 (±3.0), 22.5 (±3.4) and 74.6 (±17.2) were found for the PSQI, MMSE and BI, respectively. The changes identified in the other instruments were recorded in 46 ICF categories, with the most frequent component being "Body Functions", followed by "Activities and Participation". We found an inter-rater agreement of 0.87 for the PSQI (substantial), 0.44 for the MMSE (moderate) and 0.39 for BI (fair). CONCLUSIONS: The results indicate that the instruments' concordance differed greatly, which suggests a more thorough use of these instruments in physical therapy to optimize the formulation and standardization of diagnoses.

ABSTRACT

Contextualização: Diversos estudos têm avaliado a função motora de crianças com Paralisia Cerebral (PC), entretanto pouco se sabe sobre as inter-relações entre comprometimentos da mobilidade, autocuidado e função social relacionadas às habilidades funcionais da criança e à assistência do cuidador. OBJETIVOS: Identificar diferenças funcionais de crianças com PC em diferentes níveis de disfunção motora e correlacioná-las com os domínios mobilidade, autocuidado e função social na habilidade funcional e na assistência do cuidador. MÉTODOS: Realizou-se uma pesquisa analítica de corte transversal com 70 crianças/famílias, com idades de 4 a 7,5 anos, atendidas no Centro de Reabilitação Infantil, por meio do Pediatric Evaluation Disability Inventory (PEDI) e do Gross Motor Function Classification System (GMFCS). A análise dos dados foi realizada por meio da ANOVA e teste de correlação de Pearson. RESULTADOS: Os resultados indicaram importante variabilidade funcional das crianças com PC em diferentes níveis de severidade da disfunção motora. Essa variação foi observada nos domínios mobilidade, autocuidado e função social. Os resultados apresentaram, também, forte correlação entre os domínios mobilidade e autocuidado e mobilidade e função social. CONCLUSÕES: Diante da variabilidade apresentada pelas crianças, percebe-se a necessidade de aplicação do PEDI e GMFCS, o que parece aumentar o entendimento sobre a relação entre funções motoras grossas e atividades da vida diária. Essa correlação demonstra o quanto a mobilidade é determinante para avaliar o desempenho funcional e orientar a prática terapêutica no sentido de desenvolver as potencialidades das crianças, bem como orientar o cuidador na estimulação.


Background: Several studies have evaluated motor function among children with cerebral palsy (CP), but little is known about how mobility impairment, self-care and social function interrelate with their functional skills and caregiver assistance. OBJECTIVES: To identify functional differences among children with CP at different levels of motor dysfunction, and to investigate the relationship between these differences and the domains of mobility, self-care and social function in functional skills and caregiver assistance. METHODS: An analytical cross-sectional study was conducted among 70 children and their families. The children were aged 4 to 7.5 years and received care at the Children's Rehabilitation Center. The instruments used were the Pediatric Evaluation Disability Inventory (PEDI) and the Gross Motor Function Classification System (GMFCS). Data analysis was performed by means of ANOVA and Pearson's correlation. RESULTS: The results showed significant functional variability among the children with CP at different levels of motor dysfunction severity. This variation was observed in the domains of mobility, self-care and social function. The results also showed a strong correlation between mobility and self-care and between mobility and social function. CONCLUSIONS: In view of the variability shown by the children, it was necessary to apply PEDI and GMFCS, which appears to increase the understanding of how gross motor function relates to activities of daily living. This correlation demonstrates the extent to which mobility is a determinant for evaluating functional performance and guiding therapeutic practice to develop children's potentials and instruct caregivers in stimulation.
