Data showed improvements secondary to exercise in ' physical function ' and ' general health ' .
The other domains - ' role physical ' , ' bodily pain ' , ' vitality ' , ' social ' , ' role emotional ' , and ' mental health ' - did not show improvement at six months .
Although results showed significant heterogeneity between trials , population s and outcomes were comparable overall , with findings relevant to the claudicant population .
High- quality evidence shows that exercise programmes provided important benefit compared with placebo or usual care in improving both pain-free and maximum walking distance in people with leg pain from IC who were considered to be fit for exercise intervention .
Exercise did not improve ABI , and we found no evidence of an effect of exercise on amputation or mortality .
Exercise may improve quality of life when compared with placebo or usual care .
BACKGROUND Exercise programmes are a relatively inexpensive , low-risk option compared with other , more invasive therapies for treatment of leg pain on walking ( intermittent claudication ( IC ) ) .
This is the fourth up date of a review first published in 1998 .
OBJECTIVES Our goal was to determine whether an exercise programme was effective in alleviating symptoms and increasing walking treadmill distances and walking times in people with intermittent claudication .
Secondary objectives were to determine whether exercise was effective in preventing deterioration of underlying disease , reducing cardiovascular events , and improving quality of life .
Treatment efficacy of intermittent claudication by invasive therapy, supervised physical exercise training compared to no treatment in unselected randomised patients II: one-year results of health-related quality of life.
OBJECTIVE to compare the effectiveness of invasive therapy , supervised physical training and no treatment in terms of health-related quality of life ( HRQL ) in patients with intermittent claudication ( IC ) . DESIGN a prospect i ve , r and omised , controlled study . MATERIAL S a total of 253 unselected patients with stable IC were sequentially r and omised into 3 balanced treatment groups . At 1 year follow-up data from a battery of generic and disease specific HRQL question naires , and global indices of quality of life and physical condition were available in 171 patients . RESULTS compared with a non-diseased reference group , claudicants were substantially limited in daily physical functioning , but little affected regarding emotional , cognitive and social functioning , or well-being .  Invasive therapy yielded significantly greater improvements in some aspects of physical functioning and walk-related symptoms than training . Training was not superior to invasive therapy on any HRQL dimension and superior to no treatment on only one dimension . Treatment effects , however , were generally small-to-moderate and levels of physical dysfunction in all groups remained higher than reference values . CONCLUSIONS invasive therapy is more effective than supervised training in alleviating illness-specific symptoms and improving certain aspects of physical functioning - the primary HRQL domains impacted on by IC and the principal goals of its treatment . However , since treatment effect sizes were at most moderate and given that untreated claudicants reported at most small deterioration in HRQL , the level of evidence supporting invasive therapy is modest
