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 .
Comparison of the effect of upper body-ergometry aerobic training vs treadmill training on central cardiorespiratory improvement and walking distance in patients with claudication.
BACKGROUND Supervised treadmill-walking exercise programs have been proven to be a highly effective in improving walking distance in peripheral arterial disease ( PAD ) patients with lifestyle-limiting claudication . Limited information is available on the contributions of central cardiorespiratory functions for improving these patients ' walking capacity with exercise training . METHODS This study r and omized 28 participants ( 21 men ; age , 65.6 years ; 92.7 % smoking history , 36.6 % with diabetes ) with lifestyle-limiting PAD-related claudication to 3 hours/week of supervised exercise training for 12 weeks  , using arm-ergometry ( n = 10 ) or treadmill-walking ( n = 10 ) vs a usual-care control group ( n = 8) . Cardiorespiratory function measurements were assessed before and after training at a submaximal workload and at the onset of claudication ( pain-free walking distance [ PFWD ] ) and at maximal walking distance [ ( MWD ] ) . Changes in these functions from baseline were analyzed among the groups with analysis of covariance . Associations between variables were determined by Pearson 's partial correlations . RESULTS The mean baseline demographic , medical , and exercise variables were similar among the groups . There were similar significant differences in the submaximal double product ( heart rate × systolic blood pressure ) and at MWD , ventilatory threshold , ventilatory oxygen uptake ( VO(2 ) ) at onset of claudication , and VO(2 ) peak in response to training in both exercise groups vs the control group . Statistically significant , moderate correlations ( r = 0.60 - 0.68 ) were found between changes in all cardiorespiratory variables and changes in PFWD or MWD . CONCLUSION Improvements in cardiorespiratory function after arm-ergometry or treadmill-training were significantly associated with improvements in both PFWD and MWD , providing supporting evidence of systemic contributions to exercise training-related improvements in walking capacity seen in patients with claudication
