The HBET group did not show improvement in MWD/T compared with the WA group ( SMD 0.30 , 95 % CI -0.45 to 1.05 ; P = 0.43 ; moderate- quality evidence ) .Compared with HBET , SET was more beneficial for PFWD/T but had no effect on quality of life parameters nor on self-reported functional impairment .
Compared with WA , SET was more beneficial for PFWD/T and self-reported functional impairment , as well as for some quality of life parameters ( e.g. , physical functioning , pain , and physical component summary after 12 months ) , and HBET had no effect .
Data show no obvious effects on mortality rates .
Evidence of moderate and high quality shows that SET provides an important benefit for treadmill-measured walking distance ( MWD and PFWD ) compared with HBET and WA , respectively .
Although its clinical relevance has not been definitively demonstrated , this benefit translates to increased MWD of 120 and 210 meters after three months in SET groups .
These increased walking distances are likely to have a positive impact on the lives of patients with IC .
Data provide no clear evidence of a difference between HBET and WA .
Trials show no clear differences in quality of life parameters nor in self-reported functional impairment between SET and HBET .
BACKGROUND Although supervised exercise therapy ( SET ) provides significant symptomatic benefit for patients with intermittent claudication ( IC ) , it remains an underutilized tool .
Widespread implementation of SET is restricted by lack of facilities and funding .
Structured home-based exercise therapy ( HBET ) with an observation component ( e.g. , exercise logbooks , pedometers ) and just walking advice ( WA ) are alternatives to SET .

OBJECTIVES The primary objective was to provide an accurate overview of studies evaluating effects of SET programs , HBET programs , and WA on maximal treadmill walking distance or time ( MWD/T ) for patients with IC .
Secondary objectives were to evaluate effects of SET , HBET , and WA on pain-free treadmill walking distance or time ( PFWD/T ) , quality of life , and self-reported functional impairment .
Exercise rehabilitation improves functional outcomes and peripheral circulation in patients with intermittent claudication: a randomized controlled trial.
OBJECTIVE To determine the effects of a 6-month exercise program on ambulatory function , free-living daily physical activity , peripheral circulation , and health-related quality of life ( QOL ) in disabled older patients with intermittent claudication . DESIGN Prospect i ve , r and omized controlled trial . SETTING University Medical ( Center and Veterans Affairs Medical Center , Baltimore , Maryl and . PARTICIPANTS Thirty-one of 61 patients with Fontaine stage II peripheral arterial occlusive disease ( PAOD ) were r and omized to  exercise rehabilitation and 30 to  usual-care control . Three patients from the exercise group and six patients from the control group dropped out , leaving 28 and 24 patients , respectively , completing the study in each group . INTERVENTION Six months of exercise rehabilitation . MEASUREMENTS Treadmill distance walked to onset of claudication and to maximal claudication , ambulatory function , peripheral circulation , perceived QOL , and daily physical activity . RESULTS Compliance with the exercise program was 73 % of the possible sessions . Exercise rehabilitation increased treadmill distance walked to onset of claudication by 134 % ( P < .001 ) and to maximal claudication by 77 % ( P < .001 ) , walking economy by 12 % ( P = .003 ) , 6-minute walk distance by 12 % ( P < .001 ) , and maximal calf blood flow by 30 % ( P < .001 ) . Changes in distance walked to maximal pain correlated with changes in walking economy ( r = -.50 , P = .013 ) and changes in maximal calf blood flow ( r = .38 , P = .047 ) . Exercise rehabilitation increased accelerometer-derived daily physical activity by 38 % ( P < .001 ) ; this change correlated with the change in distance walked to maximal pain ( r = .45 , P = .020 ) . These improvements were significantly better than the changes in the control group ( P < .05 ) . CONCLUSION Improvements in claudication following exercise rehabilitation in older PAOD patients are dependent on improvements in peripheral circulation and walking economy . Improvement in treadmill claudication distances in these patients translated into increased accelerometer-derived physical activity in the community , which enabled the patients to become more functionally independent
