Comparison between the six-minute walk test and the six-minute step test in post stroke patients

Abstract

BackgroundThe Stroke remains one of the major chronic diseases worldwide, and is considered a major cause of disability, which results not only in persistent neurological deficits, but also in the high physical deconditioning, nevertheless there are not many forms of assessing functional capacity in this population. We aimed to investigate the feasibility of the Six Minute Walk Teste and the Six-Minute Step Test (6MST) in post-stroke patients and compare the behavior of physiological variables during the 6MST and the Six-Minute Walk Test (6MWT), by correlating the functional performance obtained in both tests.MethodThe 6MWT was carried out according to the American Thoracic Society (ATS) and the 6MST was performed in six minutes in order to compare it to the 6MWT in a 20 cm step. Was included post-stroke individuals able to walk without aid. All of them did the 6MWT and the 6MST.Results12 patients participated in the study. There was no statistical difference in the parameters analyzed when tests were compared. There was poor correlation between the functional performance in both tests.ConclusionThe 6MWT and the 6MST is feasible for post-stroke patients and physiological responses are equal during the performance of both tests. However, there was no correlation with respect to functional performance, which was assessed by the distance walked in the 6MWT and by the number of steps climbed in the 6MST.

Construct validity and reproducibility of the six-minute step test in subjects with obstructive sleep apnea treated with continuous positive airway pressure

“…Similar results were found in a study by da Costa et al, 24 in which healthy sedentary individuals were evaluated. However, da Silva et al, 25 when comparing these variables in individuals who had a stroke and underwent the 6MST and the 6MWT, found no differences between the tests. The greater cardiovascular stress produced by the 6MST can be attributed to the fact that the 6MST requires greater leg muscle activity than does the 6MWT.…”

Respostas Cardiorrespiratórias Durante Dois Testes De Exercício Submáximos Em Participantes De Um Programa De Reabilitação Cardíaca: Resultados Preliminares

“…São inexistentes os estudos que tenham analisado as diferentes respostas cardiorrespiratórias e percepção de esforço obtidas entre o TC6m e o TD4 dentro da prática clínica da reabilitação cardíaca. Entretanto, é importante mencionar o estudo de Silva et al 20 que, apesar de ter sido conduzido com uma população (pacientes em reabilitação por acidente vascular encefálico) diferente da do nosso estudo, comparou o comportamento das variáveis cardiorrespiratórias durante o TC6m e o teste do degrau de seis minutos (TD6), não encontrando diferença significativa entre as variáveis fisiológicas analisadas (SpO 2 , FC, PAS, PAD e percepção de esforço), nem associação entre a distância percorrida no TC6m e o número de degraus no TD6. Schnaider e Karsten21 avaliaram a tolerância ao exercício em oito pacientes do gênero masculino, hospitalizados devido à exacerbação da DPOC, através do TC6m e do TD6.…”

The Importance of the Double Product in the Six-Minute Walk Test to Predict Myocardial Function

“…In our study, no correlation between the growth of the double product and the distance of the walk has been demonstrated (data not shown). Other authors, in order to assess the physical capacity of the patients after stroke, compared the 6MWT and the 6-minute step test (6MST) [ 36 ]. In both tests, the only parameter analyzed was the double product.…”
