Validação e reprodutibilidade do teste de atividade de vida diária-Glittre para avaliar a capacidade funcional de idosos

Abstract

Introduction: The Glittre-Activity Daily Living (Glittre-ADL) Test showed to be a complete tool to evaluate the functional development; however, it has not yet been investigated in the healthy elderly population. Objective: To verify whether the Glittre-ADL is valid for evaluating the functional capacity (FC) in the elderly, to analyse the inter-rater and intra-rater reproducibility and to compare the test performance with different classifications regarding the level of physical fitness (PF) in the elderly. Methodology: A cross-transversal study composed of 100 elderly, 68,16±5,16 years, both sexes. The construct validity of the Glittre-ADL test was made by its correlation with the six-minute walk distance (6MWD) and the Timed up and Go Test (TUG) according to the best result of each patient. The intra-rater reproducibility was made by the rater 1 on the same day with an interval of 30 minutes and the inter-rater reproducibility was done by the rater 2, with a minimal interval of 24 hours and a maximum interval of 7 days. Results: There was a correlation between the Glittre-ADL test time with the 6MWD (r=-0,76; p<0,001) and the TUG (r=0,77; p<0,001). The intra-rater reliability (intraclass correlation coefficient, ICC = 0,90 and the confidence interval (CI) 95%, CI95% = 0,86-0,93; p<0,001) and the inter-rater (ICC=0,91; CI95%: 0,88-0,94; p<0,001). The Standard Error of Measurement (SEM) intra-rater was 0,03 min and inter-rater 0,05 min. The Minimal Detectable Change (MDC) intra-rater was 0,40 min and inter-rater 0,07 min. There was no significance (U=973,500; p>0,28) as for the comparison level of PF and the Glitter-ADL. Conclusion: The Glittre-ADL proved to be valid and reproducible to evaluate the FC in the elderly. There was no significance between PF level and time performance of ADL-Glittre test.
