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 .
Repeatability of the 6-minute walk test in adolescents and adults with cystic fibrosis.
OBJECTIVE To determine the repeatability of the 6-minute walk test ( 6MWT ) in adolescents and adults with cystic fibrosis ( CF ) . METHODS This was a prospect i ve cross-sectional study . We included consecutive patients ages > or=15 years attending an adult CF program . The patients underwent the 6MWT , pulmonary function tests , and clinical evaluation . The second 6MWT was performed following a rest period of 60 min . RESULTS Thirty-one patients were included . The mean+/-SD age was 23.5+/-6.7 y , and the mean FEV1 was 61+/-28 % of predicted . The mean+/-SD walked distance in the first 6MWT was 583.6+/-68.6 m and in the second 6MWT was 590.0+/-72.2 m. The mean difference between the first and second 6MWT was -6.5 m , with limits of agreement between -74.9 m and 61.9 m , and the coefficient of variation was 4.3 % . The mean oxygen desaturation in the first 6MWT was 2.5+/-4.5 % , and in the second test it was 1.8+/-4.0 % . The mean difference between the first and second test was 0.6 % , and the coefficient of variation was 104 % . CONCLUSIONS Although the 6MWT distance was reproducible , the wide limits of agreement exceeded the minimum important difference for this test . These findings indicate that , in the routine evaluation of CF patients , at least two 6MWTs are required on any testing occasion to obtain a reliable estimate of the 6MWT distance
