Based on a low quality of evidence , home-based supervised exercise may lead to less improvement in maximum and pain-free walking distance , and in more improvement in daily life walking capacity , compared with hospital-based supervised exercise .
Home-based supervised exercise may improve maximum and pain-free walking distance compared with " go home and walk advice " and result in little or no difference in health-related quality of life and functional walking capacity compared with hospital-based supervised exercise or " go home and walk advice " .
OBJECTIVE To evaluate the effects of home-based supervised exercise vs hospital-based supervised exercise , and the effects of home-based supervised exercise vs unsupervised " go home and walk advice " on daily life and corridor-walking capacity , health-related quality of life and patient-reported functional walking capacity in patients with intermittent claudication .
The relationship of walking distances estimated by the patient, on the corridor and on a treadmill, and the Walking Impairment Questionnaire in intermittent claudication.
OBJECTIVE Physicians and patients consider the limited walking distance and perceived disability when they make decisions regarding ( invasive ) treatment of intermittent claudication ( IC ) . We investigated the relationship between walking distances estimated by the patient , on the corridor and on a treadmill , and the  Walking Impairment Question naire ( WIQ ) in patients with IC due to peripheral arterial disease . METHODS This was a single-center , prospect i ve observational cohort study at a vascular laboratory in a university hospital in the Netherl and s. The study consisted of 60 patients ( 41 male ) with a median age of 64 years ( range , 44 - 86 years ) with IC and a walking distance ≤ 250 m on a st and ardized treadmill test .  Main outcome measures were differences and Spearman rank correlations between pain-free walking distance , maximum walking distance ( MWD ) estimated by the patient , on the corridor and on a st and ardized treadmill test , and their correlation with the WIQ . RESULTS The median patients ' estimated , corridor , and treadmill MWD were 200 , 200 , and 123 , respectively ( P < .05 ) . Although the median patients ' estimated and corridor MWD were not significantly different , there was a difference on an individual basis . The correlation between the patients ' estimated and corridor MWD was moderate ( r = 0.61 ; 95 % confidence interval [ CI ] , 0.42 - 0.75 ) . The correlation between patients ' estimated and treadmill MWD was weak ( r = 0.39 ; 95 % , CI 0.15 - 0.58 ) . Respective correlations for the pain-free walking distance were comparable . The patients ' estimated MWD was moderately correlated with WIQ total score ( r = 0.63 ; 95 % , CI 0.45 - 0.76 ) and strongly correlated with WIQ distance score ( r = 0.81 ; 95 % CI , 0.69 - 0.88 ) . The correlation between the corridor MWD and WIQ distance score was moderate ( r = 0.59 ; 95 % CI , 0.40 - 0.74 ) . CONCLUSIONS Patients ' estimated walking distances and on a treadmill do not reflect walking distances in daily life . Instruments that take into account the perceived walking impairment , such as the WIQ , may help to better guide and evaluate treatment decisions
