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 .
Predictors of treatment outcome in intermittent claudication.
OBJECTIVE To derive formulae to predict the likely 12-month health-related quality of life outcome following different treatments for intermittent claudication ( IC ) . DESIGN A prospect i ve , r and omized , controlled study . MATERIAL S One hundred and seventy-one unselected patients with stable IC were sequentially r and omized to invasive therapy , supervised physical training or observation . Hierarchical analysis was used to identify significant predictors of outcome . RESULTS The strongest outcome predictors were baseline values of the respective outcome variables in all groups . No more than two significant secondary predictors were identified for each outcome variable and no outcome variable was a predictor of any other outcome variable . Result ing prediction equations achieved between 61 and 90 % concordance with improvement ( 75 % considered adequate ) , with best prediction for invasive therapy and poorest for observation . Suggested cutpoints for the various endpoints in the three groups had sensitivities ranging between 65 and 100 % and false positive rates between 5 and 50 % . CONCLUSIONS The derived equations adequately predicted improvement on the various outcome variables in invasive therapy and supervised physical training , and may serve as aids in selecting patients likely to benefit most from a particular treatment strategy . The uniqueness of the outcome variables underscores the importance of implementing a comprehensive set of endpoints relevant to the impacts of the condition
