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 .
Step‐Monitored Home Exercise Improves Ambulation, Vascular Function, and Inflammation in Symptomatic Patients With Peripheral Artery Disease: A Randomized Controlled Trial
Background This prospect i ve , r and omized , controlled clinical trial compared changes in primary outcome measures of claudication onset time ( COT ) and peak walking time ( PWT ) , and secondary outcomes of submaximal exercise performance , daily ambulatory activity , vascular function , inflammation , and calf muscle hemoglobin oxygen saturation ( StO2 ) in patients with symptomatic peripheral artery disease ( PAD ) following new exercise training using a step watch ( NEXT Step ) home‐exercise program , a supervised exercise program , and an attention‐control group . Methods and Results One hundred eighty patients were r and omized . The NEXT Step program and the supervised exercise program consisted of intermittent walking to mild‐to‐moderate claudication pain for 12 weeks , whereas the controls performed light resistance training . Change scores for COT ( P<0.001 ) , PWT ( P<0.001 ) , 6‐minute walk distance ( P=0.028 ) , daily average cadence ( P=0.011 ) , time to minimum calf muscle StO2 during exercise ( P=0.025 ) , large‐artery elasticity index ( LAEI ) ( P=0.012 ) , and high‐sensitivity C‐reactive protein ( hsCRP ) ( P=0.041 ) were significantly different among the 3 groups . Both the NEXT Step home program and the supervised exercise program demonstrated a significant increase from baseline in COT , PWT , 6‐minute walk distance , daily average cadence , and time to minimum calf StO2 . Only the NEXT Step home group had improvements from baseline in LAEI , and hsCRP ( P<0.05 ) . Conclusions NEXT Step home exercise utilizing minimal staff supervision has low attrition , high adherence , and is efficacious in improving COT and PWT , as well as secondary outcomes of submaximal exercise performance , daily ambulatory activity , vascular function , inflammation , and calf muscle StO2 in symptomatic patients with PAD .
