Correlation between six minute walk test
and spirometry in chronic pulmonary disease.

Hence, it is concluded that six minute walk test
is a useful tool in assessing the severity of chronic obstructive pulmonary disease patients.
The scientific literature was reviewed in order to support the selection of the fitness tools (body mass index, percent body fat, manual muscle test, and six minute walk test
) used in this case, and to answer the background questions.
Secondary study endpoints also showed tafamidis reduced the decline in the six minute walk test
distance, a measure of functional capacity, and reduced the decline in aspects of quality of life measured by the Kansas City Cardiomyopathy Questionnaire - Overall Score, compared with placebo at Month 30.
The six minute walk test
(6MWT) (American Thoracic Society 2002) and then subsequently the incremental shuttle walk test (ISWT) (Singh 1992) were used to assess exercise capacity.
Data Collection: Biometric data (age, sex, height, weight), Pulmonary Function Test and Six minute walk test
of obese patients referred to PFT Lab for pre-operative investigation, admitted for planned Bariatric Surgery.
The six minute walk test
(6MWT) is an example of a functional walk test that is practical and simple and only requires the ability to walk.
At six months, patients experienced median improvement of 231 meters in the six minute walk test
, and 83% of patients improved to NYHA Class I or II status, representing statistically significant improvements compared with baseline status.
van Eijkeren et al (2008) had similar findings with the participants having significantly better physical function (p < 0.01) on the PDQ-39, the Timed Up and Go test (TUG), 10 metre walk test (10MWT) and the six minute walk test
(6MWT) at the end of the Nordic walking.
An exact list of medical subject heading (MeSH) terms were used to search the databases including pairing the following words: "heart failure," "submaximal exercise tolerance," "tread-mill test," "stress test," "exercise test," "exercise tolerance test," "exercise capacity," "6 minute walk test," "six minute walk test
," "prognosis," "prognostic indicator," "function," "functional capacity," "functional outcomes," "reliable," "reliability," "validity," "valid," "outcome measure," "reproducibility," "reproducibility of results," and "reproducibility of findings."
At the six month time point, patients are demonstrating an average improvement in exercise capacity or a six minute walk test
of approximately 68 meters as compared to an average improvement of 47 meters at three months.
