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 .
The incremental shuttle walking test in elderly people with chronic airflow limitation
Background : There is a concern that comorbidity or frailty in older people could limit the usefulness of currently available exercise tests for chronic lung disease . This study evaluated the feasibility and reproducibility of the incremental shuttle walking test ( SWT ) in people aged 70 years or over , compared exercise tolerance with other disability markers , and assessed whether the SWT is responsive to change after bronchodilators . Methods : Fifty elderly patients with chronic airflow limitation ( CAL ) and 32 controls without airflow limitation attempted the SWT before and after combined nebulised salbutamol/ipratropium bromide . Subjects also completed the Nottingham Extended Activities of Daily Living index ( NEADL ) and the London H and icap score ( LHS ) . Results : Forty four subjects with CAL ( 88 % ) and 29 controls ( 84 % ) completed the SWT , including many with co-morbidities . Two week repeatability was good and the SWT was strongly associated with EADL ( r=0.51 , p<0.001 ) and LHS ( r=0.43 , p<0.004 ) , but only weakly with forced expiratory volume in 1 second ( FEV1 ) ( r=0.31 , p=0.05 ) . Subjects with CAL walked a mean distance of 177.7 m compared with 243.3 m in controls ( p<0.001 ) ; following bronchodilator therapy the distance walked increased in the CAL group by 13.2 % ( p=0.009 ) . Conclusion : The SWT is a feasible and reproducible measure of exercise tolerance in elderly people with and without airflow obstruction and correlates with other markers of disability . It is sensitive to change following bronchodilation in subjects with CAL , although the change correlates less well with improvements in FEV1 . Overall , these results suggest that the SWT might be an appropriate measure to assess interventions in elderly people
