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 .
Activity levels after pulmonary rehabilitation - what really happens?
OBJECTIVES To assess the changes in  physical activity  in subjects with chronic obstructive pulmonary disease over 6months after pulmonary rehabilitation . DESIGN Prospect i ve , observational study .  Activity  was measured over 2-day periods at the end of rehabilitation , and repeated every 6weeks for 6months using the ActivPAL uni-axial accelerometer . These results were compared with the shuttle walking test ( SWT ) and the St. George 's Respiratory Disease Question naire ( SGRDQ ) . SETTING UK community hospital . PARTICIPANTS Adults completing a community rehabilitation programme . MAIN OUTCOME MEASURE Time spent st and ing and mobilising ( ' uptime ' ) . RESULTS Of 34 subjects recruited , 28 completed the 6-month study period ( mean age 69years , mean forced expiratory volume in 1second 1.3l ) . Participants wore the monitor for 13.8 to 14.2hours/day . At baseline ( post-rehabilitation ) , participants spent 1.7 [ st and ard deviation ( SD ) 1.3]hours/day walking and 3.5 ( SD 2.6)hours/day st and ing . Taking the group as a whole , mean uptime decreased marginally by 13.6minutes after 24weeks compared with baseline , with significant individual variability . In all but one subject who showed decreased activity , this was apparent after 6weeks . There were no significant changes in the mean SWT or SGRDQ . Significant associations between total uptime and the SWT were found , but coefficients were weak . It was not possible to predict individual responses from baseline data . CONCLUSION The accelerometer provides useful supplementary data in patients completing rehabilitation programmes , and the results reveal wide variation . The weak associations between activity data and the SWT suggest that monitors provide additional information . More work is required to determine the factors associated with early deterioration in activity in order to design appropriate interventions
