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 .
Exercise training in intermittent claudication.
BACKGROUND Peripheral arterial occlusive disease ( PAOD ) at II stage results in a moderate to severe impairment in walking ability . Aim of this study , controlled and r and omized , was to evaluate the efficacy of an intensive 4 weeks exercise training in PAOD followed by a six-month period and to analyse the risk factors for atherosclerosis and the site of the lesion for possible predictors of result outcome . METHODS Patients with PAOD were included in the study ( ankle/arm ratio < or = 0.7 and < or = 0.5 after exercise ) with initial claudication distance ( ICD ) < or = 200 m and absolute claudication distance ( ACD ) < or = 500 m evaluated on a constant-load treadmill test ( 3 km/hr , 0 % slope ) . Forty patients were r and omized ( all with antiplatelet therapy ) : 20 to a supervised walking exercise ( mean ICD 121.8 m , ACD 289.7 m ) and 20 to a non exercising control group ( ICD 111.6 m , ACD 230.1 m ) . Both groups were tested at 4 weeks ( T1 ) and 6 months ( T2 ) . Training group was enrolled in a 4-week supervised training program . RESULTS In the training group 10 % of patients became asymptomatic ( > 1000 m ) . At T1 ICD increased 141 % ( p<0.001 ) and ACD was with low-pain-claudication > 1000 m in 50 % , at T2 ICD was 200 % ( p<0.05 ) with 70 % of asymptomatic for ICD and ACD . Control group has a no significant increase of ICD and ACD at T1 and T2 . Only arterial hypertension and intermittent claudication severity emerged as negative predictive factors for the results of training . CONCLUSIONS Vascular training produces a significant and lasting improvement in walking distance in PAOD
