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 .
Unsupervised Exercise and Mobility Loss in Peripheral Artery Disease: A Randomized Controlled Trial
Background Few medical therapies improve lower extremity functioning in people with lower extremity peripheral artery disease ( PAD ) . Among people with PAD , we studied whether a group-mediated cognitive behavioral intervention promoting home-based unsupervised exercise prevented mobility loss and improved functional performance compared to control . Methods and Results One hundred ninety-four PAD participants were r and omized . During months 1 to 6 , the intervention group met weekly with other PAD participants and a facilitator . Group support and self-regulatory skills were used to help participants adhere to walking exercise . Ninety-percent of exercise was conducted at or near home . The control group attended weekly lectures . During months 6 to 12 , each group received telephone contact only . Primary outcomes have been reported . Here we compare changes in exploratory outcomes of mobility loss ( the inability to climb a flight of stairs or walk one-quarter mile without assistance ) , walking velocity , and the Short Physical Performance Battery . Compared to controls , fewer participants r and omized to the intervention experienced mobility loss at 6-month follow-up : 6.3 % versus 26.5 % , P=0.002 , odds ratio=0.19 ( 95 % CI=0.06 to 0.58 ) and at 12-month follow-up : 5.2 % versus 18.5 % , P=0.029 , odds ratio=0.24 ( 95 % CI=0.06 to 0.97 ) . The intervention improved fast-paced 4-m walking velocity at 6-month follow-up ( P=0.005 ) and the Short Physical Performance Battery at 12-month follow-up ( P=0.027 ) , compared to controls . Conclusions In exploratory analyses , a group-mediated cognitive behavioral intervention promoting unsupervised walking exercise prevented mobility loss and improved functioning at 6- and 12-month follow-up in PAD patients .
