ABSTRACT

Objetivo: Correlacionar a força muscular respiratória e a capacidade funcional em pacientes com FC. Métodos: Estudo transversal em adultos com fibrose cística. Os dados amostrais foram catalogados no Microsoft Office Excel 2007 e as variáveis analisadas pelo SPSS versão 20.0 através do teste t de Student e do coeficiente de Spearman. O nível de significância adotado foi p < 0,05. Resultados: Foram avaliados 35 pacientes com fibrose cística (44,6 ± 19,0 anos), grande parte dos pacientes de FC (n=26) não apresentaram fraqueza da musculatura inspiratória (PImáx -90,7 ± 27,4 cmH2O). Não foi encontrada estatística significativa apenas entre os pacientes adultos e idosos. Houve correlação positiva entre PImáx, PEmáx e teste de caminhada de 6 minutos (TC6) nos participantes com fraqueza muscular respiratória e nos idosos. Houve diferença estatisticamente significativa entre as médias da distância percorrida no TC6 e das pressões respiratórias máximas com a média do que foi previsto para estas variáveis. Conclusão: Todos os grupos apresentaram limitação da força respiratória e da capacidade funcional. As correlações entre as pressões respiratórias com o TC6 foram baixas e pequenas nos adultos e indivíduos sem fraqueza muscular respiratória; moderadas à alta nos idosos; pequenas à moderada nas mulheres; pequenas e negativas nos homens; e, altas naqueles com fraqueza muscular respiratória


Objective: To correlate the respiratory muscle strength and functional capacity in patients with CF. Method: Cross-sectional study in adults with cystic fibrosis. Sampling data were cataloged in Microsoft Office Excel 2007 and the variables analyzed by SPSS version 20.0 using the Student t test and the Spearman coefficient. The level of significance adopted was p < 0.05. Results: We assessed 35 patients with cystic fibrosis (44.6 ± 19.0 years), the great majority of patients in FC (n=22) did not present weakness of the inspiratory muscles (MIP -90,7 ± 27.4 cmH2O). It was not found statistically significant differences only between the adult and elderly patients. There was a positive correlation between MIP and MEP and a six-minute walk test (6MWT) in participants with respiratory muscle weakness and in the elderly. There was statistically significant difference between the averages of the distance covered on the 6MWT and the maximal respiratory pressures with the average of what was envisaged for these variables. Conclusion: All groups presented limitation of respiratory strength and functional capacity. The correlations between the respiratory pressures with the 6MWT were low and small in adults and individuals without respiratory muscle weakness; moderate to high in the elderly; small to moderate in women; small and negative in men; and high in patients with respiratory muscle weakness
