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 .
Fatigue in patients with chronic obstructive pulmonary disease.
BACKGROUND Fatigue is a frequently occurring symptom in patients with chronic obstructive pulmonary disease ( COPD ) . Despite this , relatively few studies have objective ly assessed patients ' perceptions of fatigue and the impact of perceived fatigue on their everyday lives . OBJECTIVE The purpose of this study was to describe the prevalence , duration and severity of fatigue among patients with COPD and the impact of perceived fatigue on cognitive , physical and psychosocial functioning in comparison with controls . METHOD The  Fatigue Impact Scale , including physical , psychosocial and cognitive dimension and structured questions about the frequency , duration , and severity of fatigue  was mailed to 44 out patients with COPD and 88 r and omly selected age- and sex-matched controls . In total 36 patients and 37 controls completed the question naire . RESULTS Almost half of the patients ( 47.2 % ) , reported fatigue every day during the preceding month compared with 13.5 % of the control group ( P < 0.001 ) . The duration of fatigue was more than 6 hours in 52.7 % of the patients and 44.4 % reported that fatigue was either the worst or one of the worst symptoms they had , compared with 18.9 % ( P < 0.001 ) and 10.8 % ( P < 0.01 ) in the control group . The patients reported a significantly greater impact of fatigue on cognitive , physical and psychosocial functioning compared with the control group ( P < 0.001 ) . CONCLUSION These findings indicate that fatigue is a highly prevalent symptom , which impacts on patients ' functional condition and needs to be professionally assessed and managed
