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 .
Baseline 6‐Min Walk Distance Predicts Survival in Lung Transplant Candidates
In a large , prospect ively followed , two‐center cohort of patients listed for lung transplantation ( n = 376 ) , we used Cox proportional hazards models to determine the importance of baseline 6‐min walk distance ( 6MWD ) in predicting patient survival . 6MWD used as a continuous variable was a significant predictor of survival after adjusting for other important covariates when transplant was considered as a time‐varying covariate ( HR for each 500 ft increase in 6MWD = 0.57 , 95 % CI : 0.43–0.77 , p = 0.0002 ) . 6MWD remained an important predictor of survival in models that considered only survival to transplant ( HR for each 500 ft increase in 6MWD = 0.41 , 95 % CI : 0.27–0.62 , p < 0.0001 ) or survival only after transplant ( HR for each 500 ft increase in 6MWD = 0.40 , 95 % CI : 0.22–0.72 , p = 0.002 ) . Unadjusted Kaplan‐Meier analysis demonstrates significantly different survival by 6MWD tertiles ( < 900 , 900–1200 , or > 1200 ft , p‐value = 0.0001 ) . In the overall model , 6MWD prediction of survival was relatively homogeneous across disease category ( 6MWD by disease interaction term , p‐value = 0.63 ) . Our results demonstrate a significant relationship between baseline 6MWD and survival among patients listed for lung transplantation that exists across all native disease categories and extends through transplantation . The 6MWD is thus a useful measure of both urgency and utility among patients awaiting lung transplantation
