Tradução para o português (Brasil), adaptação transcultural, confiabilidade e validação da Functional Ambulation Classification – FAC, para categorização da deambulação após Acidente Vascular Cerebral

Abstract

Objective: To translate and culturally adapt the FAC to Portuguese (Brazil) and test its reliability and validity of competing criteria for individuals affected by chronic stroke. Methodology: The process of transcultural translation and adaptation followed 6 steps. The inter-rater reliability was tested by five physiotherapists who watched videos of the individuals' ambulation. For intra-rater analysis, a minimum period of seven days was considered. For analysis of concurrent criterion validity correlated with the FAC walk 10 meters test (TC10M). For the normality of the data the Kolmogorov-Smirnov and Kappa reliability were used. The Spearman correlation coefficient (rS) and the chi-square test to determine the categorization of the association gait by FAC and the speed of travel. Results: In-rater reliability ranged from k=0.680 to k= 0.952; p=0.001 and to inter-raters of k=0.517 to 0.794; p=0.001. The correlation between FAC and TC10M values was rS=0.771 p=0.001. There was an association between FAC scores and walking speed [x2 (9) = 145,335; p=0.001]; being that in 48% the variables are correctly associated (Cramer's V). Conclusion: translation, cultural adaptation and analysis of measurement properties demonstrated that the FAC is a valid and reliable clinical measure of ambulation for categorization of the Brazilian population with chronic stroke.
