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 .
Long-term effects of structured home-based exercise program on functional capacity and quality of life in patients with intermittent claudication.
OBJECTIVES To evaluate effects of a structured home-based exercise program on functional capacity and quality of life ( QoL ) in patients with intermittent claudication ( IC ) after 1-year follow-up , and to compare these results with those from a concurrent control group who received supervised exercise training ( SET ) . DESIGN Comparative longitudinal cohort study . SETTING Referral center . PARTICIPANTS Patients ( N=142 ) with IC . INTERVENTIONS Structured home-based exercise training or SET . MAIN OUTCOME MEASURES The maximum ( pain-free ) walking distance and the ankle-brachial index ( ABI ) ( at rest and postexercise ) were measured at baseline and after 6 and 12 months ' follow-up . Additionally , QoL was evaluated using a self-administered question naire consisting of the Euroqol-5D ( scale 0 - 1 ) , rating scale ( scale 0 - 100 ) , Medical Outcomes Study 36-Item Short-Form Health Survey ( SF-36 ; scale 0 - 100 ) , and the Vascular Quality of Life Question naire ( VascuQol ; scale 1 - 7 ) . Comparison of the groups was performed with adjustment for the nonr and omized setting using propensity scoring . RESULTS One hundred forty-two patients with IC started the  structured home-based exercise program , of whom 95 ( 67 % ) completed 12 months ' follow-up . The mean relative improvement compared with baseline was statistically significant after 12 months ' follow-up for the maximum and pain-free walking distance ( 342 % , 95 % confidence interval [ CI ] , 169 - 516 ; P<.01 and 338 % , 95 % CI , 42 - 635 ; P=.03 , respectively ) and for the ABI postexercise ( mean change , .06 ; 95 % CI , .01-.10 ; P=.02 ) . For the QoL outcomes , the improvement compared with baseline was statistically significant after 12 months for the VascuQol ( mean change , .42 ; 95 % CI , .20-.65 ; P<.01 ) and for the SF-36 physical functioning ( mean change , 5.17 ; 95 % CI , .77 - 9.56 ; P=.02 ) . Compared with the structured home-based exercise program , patients in the control group showed significantly better results in the mean relative improvement of maximum and pain-free walking distance and change in the ABI at rest after 12 months ' follow-up . CONCLUSIONS Structured home-based exercise training is effective in improving both functional capacity and QoL in patients with IC and may be considered as a feasible and valuable alternative toSET , since supervised exercise programs are not often available
