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 .
Relationship of shuttle walk test and lung cancer surgical outcome.
OBJECTIVE Surgery remains the treatment of choice in patients with potentially resectable lung carcinoma . Both the British Thoracic Society and American Chest Physician guidelines for the selection of patients with lung cancer surgery suggest the use of a shuttle walk test to predict outcome in patients with borderline lung function . The guidelines suggest that if the patient is unable to walk 250 m during a shuttle walk test , they are high risk for surgery . However , there is no published evidence to support this recommendation . Therefore , we undertook a prospect i ve study to examine the relationship between shuttle walk test  and surgical outcome in 139 patients undergoing assessment for possible lung cancer surgery . METHODS The shuttle walk test was performed in 139 potentially resectable patients , recruited over a 2 year period , prior to surgery . One hundred and eleven patients underwent surgery . Outcome of surgery , including duration of hospital stay , complication and mortality rates was recorded . Student 's t-test was used to compare the shuttle walk distance in patients with good and poor outcome from surgery . RESULTS Mean age of patients undergoing surgery was 69 years ( 42 - 85 ) .  Mean shuttle walk distance was 395 m ( 145 - 780 ) , with a mean oxygen desaturation of 4 % ( 0 - 14 ) during the test . Sixty nine patients had a good surgical outcome and 34 had a poor outcome . The shuttle walk distance was not statistically different in the two outcome groups . CONCLUSION Shuttle walk distance  should not be used to predict poor surgical outcome in lung cancer patients , contrary to current recommendations . It is therefore advisable to perform a formal cardiopulmonary exercise test if at all possible . The usefulness of a shuttle walk test might be improved . It could be compared to a predicted value , as for a formal cardiopulmonary exercise test
