    Associação entre a ocorrência de quedas e o desempenho no Incremental Shuttle Walk Test em mulheres idosas
    (Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia, 2012-08-01) Bardin, Marcela Grigol [UNIFESP]; Dourado, Victor Zuniga [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    BACKGROUND: Because the incremental shuttle walk test (ISWT) requires agility in its performance, we hypothesized that the test may be associated with balance and risk of falls in the elderly. Objective: To evaluate and compare the association between the performance on the ISWT, the timed up and go (TUG) and the occurrence of falls in the elderly. METHOD: Thirty-three elderly individuals (68±7 years) performed the TUG and the ISWT. Balance was assessed using the Berg Scale (BBS). Participants who fell at least twice in the last 12 months were placed in the falls group (FG) and all other participants comprised the control group (CG). RESULTS: There were seventeen elderly women in the FG and 16 in the CG. Participants from the FG had a significant worse performance (p<0.05) on the TUG (8.01±0.22 vs. 6.22±0.21 s), BBS (51±3 vs. 55±1 points) and ISWT [313±79 (92±15%pred.) vs. 395±75 m (113±19%pred.)] than participants from the CG. The ISWT significantly correlated with the TUG (r=-0.75, p<0.001), BBS (r=0.50, p=0.002) and number of falls (r=0.36, p=0.031). After logistic regression, the TUG was determinant (p=0.03) and the ISWT showed a tendency to determine the occurrence of falls (p=0.05). CONCLUSION: The ISWT was a valid measure to assess the risk of falls and balance and therefore, may be useful for the simultaneous assessment of cardiorespiratory fitness and balance in older women.

    Equações de referência para o teste de caminhada de seis minutos em indivíduos saudáveis
    (Sociedade Brasileira de Cardiologia - SBC, 2011-06-01) Dourado, Victor Zuniga [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    The six-minute walk test (6MWT) has been broadly used in clinical settings. Several reference equations for prediction of the total distance walked during the test (6MWD) are available in literature. The present review aimed to critically discuss studies, published in Portuguese and English (LILACS, SCIELO, MEDLINE, PUBMED), which evaluated normal values and created reference equations for predicting 6MWD in healthy subjects, comparing them with the results that were recently obtained in Brazilian individuals. Age, sex, weight, height and body mass index were the main demographic and anthropometric features more often correlated with 6MWD. The equations derived from these characteristics were able to explain between 25 and 66% of the total variability in the 6MWD. Unfortunately, the foreign equations were not applicable to the Brazilian population. Even when the 6MWT was performed following strict standardization, the difference in 6MWT performance between foreign and Brazilian individuals remains, indicating the necessity of providing specific reference equations for each population and/or ethnic group. Accordingly, these equations developed in Brazil are probably the most appropriate for interpreting 6MWT performance in Brazilian patients with chronic diseases affecting the exercise capacity. Future studies are necessary with larger sample sizes (e.g. multicentric ones) and randomized design for the reference values of the 6MWD to be considered reliable.

    Oxygen uptake during walking in patients with rheumatoid arthritis - A controlled study
    (J Rheumatol Publ Co, 2004-04-01) De Carvalho, MRP; Tebexreni, A. S.; Salles, CAF; Barros Neto, Turibio Leite de [UNIFESP]; Natour, J.; Universidade Federal de São Paulo (UNIFESP)
    Objective. To analyze the energy expenditure of patients with rheumatoid arthritis (RA) of functional classes I, II, and III during walking at different speeds on a treadmill.Methods. Thirty-five consecutive patients selected from the rheumatology outpatient clinic were studied and compared with a control group consisting of 35 healthy individuals paired for age, sex, body weight, and body mass index. An incremental test on a treadmill consistent with normal walking was developed, with metabolic analysis performed at 30 s intervals using a gas analyzer connected to a computerized system. Heart rate, rate of perceived exertion, visual analog scale of pain; Ritchie index, the Scale of the Escola Paulista de Medicina for Evaluation of Articular Movement Range, and the Health Assessment Questionnaire were also used to evaluate functional capacity.Results. Patients with RA showed a greater energy expenditure than controls at the following walking speeds: 3.0 km/h (RA = 229.36 +/- 56.47 kcal/h; controls = 197.44 +/- 52.59), 4.5 km/h (RA = 266.41 +/- 58.94 kcal/h; controls = 231.41 +/- 56.14), and 5.0 km/h (RA = 289.11 +/- 65.35 kcal/h; controls = 250.18 +/- 56.67). Patients with RA presented higher values for all test measures except heart rate. The functional class II group differed significantly from the controls, whereas the functional class I group had values close to normal.Conclusion. Patients with RA had a greater energy expenditure during walking compared to healthy controls under the same conditions, and patients with functional class II experienced a greater energy expenditure compared to controls.

    Six-minute walk test in healthy children: Is the leg length important?
    (Wiley-Blackwell, 2013-09-01) Oliveira, Andreia C. [UNIFESP]; Rodrigues, Camila C. [UNIFESP]; Rolim, Denise S. [UNIFESP]; Souza, Altay A. L. [UNIFESP]; Nascimento, Oliver A. [UNIFESP]; Jardim, Jose R. [UNIFESP]; Rozov, Tatiana [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Rationale Measures as height, age, and weight influence the six-minute walk test (6MWT). It was shown that children's true leg length (TLL) influence the 6MWT distance but so far it has never been evaluated how much this variable could predict the distance walked related to height. Our hypothesis is that there should not have any significant difference between models including height or TLL.Objective To establish and to compare the predicted walked distance of healthy children in the 6MWT by two distinct models, one including TLL and other including height.Methods Observational cross sectional study. A total of 161 healthy children (84 girls, 52.2%), 6-13 years old from three local primary and secondary schools. Two 6MWT were performed following ATS guidelines. Weight, height, and TLL were measured. the longer walked distance was selected for statistical analysis.Results Anthropometric data were similar for both genders into each group of age. Mean (+/- SD) walked distances in whole group were: boys 704.4m (77.7); girls 681.6m (67.9; P=0.049). in the univariate regression to predict the distance walked, the adjusted coefficients to TLL and height were in boys: 0.46 and 0.39; and in girls: 0.35 and 0.29, respectively. After adjusting for age and weight, the residuals of the two equations were not significantly different (P=0.998).Conclusion the model including TLL to predict the walked distance by healthy children explained more of the variation on the walked distance in the 6MWT than the model using the height but without significant difference between the models.
