    Objective: To evaluate the reliability and reproducibility of self-administration of the 6MWT using a free smartphone APP for step counting. Methods: In the first phase, 83 participants (44 ± 10 years, 27 ± 5 kg/m²) underwent a supervised 6MWT in a 30 m covered runner usinga a triaxial accelerometer and smartphones to compare the total step count (Npac and Npapp). We developed a multiple regression equation to estimate the distance walked on the 6MWT (D6MWT) (R² = 0.609). In the second phase, 25 participants (40 ± 10 years, 27 ± 5 kg/m²) performed the 6MWTsup and two other outdoor 6MWT (D6WMTauto1 and D6MWTauto2) using APP for Npapp counts. Results: Npac was significantly higher than Npapp (mean difference, 58 ± 136 m, p = 0,001). The reliability among these measures was weak (intraclass correlation coefficient (ICC), 0,04: 95% confidence interval (95%CI), -0,52-0,40, coefficient of variation (CV) = 42,9%). The limits of agreement between measures were also not adequate (46%), with mean difference of -8,7%. D6MWTauto2 was not significantly different from D6MWTauto1 (mean difference, 1,94 ± 30,27 m, p = 0,761). The confidence limits were lower 10% with an average difference of 0,2%. The reliability among measurements was also excellent (ICC, 0,91; 0,81-0,96; CV 6,4%). D6MWTauto1 was not significantly different from D6MWTsup (1,68 ± 61 m; p = 0,894) with moderate reliability was not significantly different from D6MWT (ICC, 0,75; 0,42-0,89; CV = 27,5%). Acceptable confidence limits (19%) with significant negative correlation between mena difference and mean values. The difference between D6MWTauto2 and D6MWTsup was not significant (3,64 ± 60,57 m, p = 0,766), good reliability (CCI = 0,79; 0,50-0,91; CV = 6%). Confidence limits lower than 19% with significant negative correlation. Conclusion: The 6MWTauto is valid and presents excellent reliability and reproducibility. Our results suggest that the use of 6MWT in people with higher CAR, when necessary, should be used with caution.

    Distância no teste de caminhada de seis minutos como marcador prognóstico no pós-operatório de cirurgia de revascularização do miocárdio
    (Universidade Federal de São Paulo (UNIFESP), 2017-03-27) Pauletti, Hayanne Osiro [UNIFESP]; Guizilini, Solange [UNIFESP]; http://lattes.cnpq.br/1563905009199506; http://lattes.cnpq.br/1452005346400152; Universidade Federal de São Paulo (UNIFESP)
    Objectives: To Investigate The Ability Of Percent-Fall In Early Postoperative Six-Minute Walk Test Distance (6Mwd), Considering The Preoperative Baseline, As A Prognostic Marker For Mid-Term Outcomes After Coronary Artery Bypass Grafiting (Cabg); And To Recognize The Independent Determinants Of Fall In 6Mwd. Methods: A Prospective Cohort With Fifty-Four Patients Undergoing Elective Cabg Was Evaluated. The Percentfall In 6Mwd Was Assessed By The Maximum Distance Achieved In Six-Minute Walk Test Preoperatively And On 5Th Day Of Postoperative (Pod5). Respiratory Muscle Strength Was Also Obtained Preoperatively And On Pod5. After Discharge, A Three Months Follow-Up Was Conducted To Assess. Results: There Was A Significant Decrease In 6Mwd On Pod5 Compared With Preoperative Baselline Values (66.9±16.5%, P<0.0001). A Moderate Negative Correlation Was Observed Between Percent-Fall Of 6Mwd And Maximum Inspiratory Pressure (R=-0.66, P<0.001) And Maximum Expiratory Pressure (R=-0.61, P<0.001) On Pod5. Additionally, The
