Method ological factors affecting 6MWD include track length , encouragement , supplemental oxygen and walking aids .
Supplemental oxygen also affects ISWT and ESWT performance .
Responsiveness was moderate to high for all tests , with greater responsiveness to interventions that included exercise training .
The findings of this review demonstrate that the 6MWT , ISWT and ESWT are robust tests of functional exercise capacity in adults with chronic respiratory disease
This systematic review examined the measurement properties of the 6-min walk test ( 6MWT ) , incremental shuttle walk test ( ISWT ) and endurance shuttle walk test ( ESWT ) in adults with chronic respiratory disease .
Six-minute walk, maximal exercise tests: reproducibility in fibrotic interstitial pneumonia.
Resting pulmonary function and exercise variables are widely used to stage and monitor idiopathic interstitial pneumonia ( IIP ) . However , the variability of exercise data ( maximal exercise and the 6-minute walk test ) has not been evaluated definitively . We have prospect ively quantified the reproducibility of resting and exercise functional data in fibrotic IIP ( idiopathic pulmonary fibrosis , fibrotic nonspecific interstitial pneumonia ) and have evaluated interrelationships between variables . Thirty consecutive patients with fibrotic IIP underwent serial resting pulmonary function tests , 6-minute walk ( n = 29 ) , and maximal exercise ( n = 24 ) at an interval of 1 week , with all testing performed in accordance with American Thoracic Society st and ards . Within-subject reproducibility was excellent for 6-minute walk distance ( SD/mean = 4.2 % ) and clinical ly acceptable for resting pulmonary function indices and VO(2)max on maximal exercise testing . However , the amplitude of oxygen desaturation at the end of exercise was poorly reproducible in both 6-minute walk and maximal exercise testing ( SD/mean > 25 % ) . There was a highly significant relationship between VO2max on maximal exercise testing and 6-minute walk distance ( r(s ) = 0.78 , p < 0.0001 ) . In fibrotic IIP , the excellent reproducibility of the 6-minute walk distance is a major advantage in routine staging and monitoring , whereas maximal exercise variables are poorly reproducible
