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 .
Treadmill exercise and resistance training in patients with peripheral arterial disease with and without intermittent claudication: a randomized controlled trial.
CONTEXT Neither supervised treadmill exercise nor strength training for patients with peripheral arterial disease ( PAD ) without intermittent claudication have been established as beneficial . OBJECTIVE To determine whether supervised treadmill exercise or lower extremity resistance training improve functional performance of patients with PAD with or without claudication . DESIGN , SETTING , AND PARTICIPANTS R and omized controlled clinical trial performed at an urban academic medical center between April 1 , 2004 , and August 8 , 2008 , involving 156 patients with PAD who were r and omly assigned to supervised treadmill exercise , to lower extremity resistance training , or to a control group .  MAIN OUTCOME MEASURES Six-minute walk performance and the short physical performance battery . Secondary outcomes were brachial artery flow-mediated dilation , treadmill walking performance , the Walking Impairment Question naire , and the 36-Item Short Form Health Survey physical functioning ( SF-36 PF ) score . RESULTS For the 6-minute walk , those in the supervised treadmill exercise group increased their distance walked by 35.9 m ( 95 % confidence interval [ CI ] , 15.3 - 56.5 m ; P < .001 ) compared with the control group , whereas those in the resistance training group increased their distance walked by 12.4 m ( 95 % CI , -8.42 to 33.3 m ; P = .24 ) compared with the control group . Neither exercise group improved its short physical performance battery scores . For brachial artery flow-mediated dilation , those in the treadmill group had a mean improvement of 1.53 % ( 95 % CI , 0.35%-2.70 % ; P = .02 ) compared with the control group . The treadmill group had greater increases in maximal treadmill walking time ( 3.44 minutes ; 95 % CI , 2.05 - 4.84 minutes ; P < .001 ) ; walking impairment distance score ( 10.7 ; 95 % CI , 1.56 - 19.9 ; P = .02 ) ; and SF-36 PF score ( 7.5 ; 95 % CI , 0.00 - 15.0 ; P = .02 ) than the control group . The resistance training group had greater increases in maximal treadmill walking time ( 1.90 minutes ; 95 % CI , 0.49 - 3.31 minutes ; P = .009 ) ; walking impairment scores for distance ( 6.92 ; 95 % CI , 1.07 - 12.8 ; P = .02 ) and stair climbing ( 10.4 ; 95 % CI , 0.00 - 20.8 ; P = .03 ) ; and SF-36 PF score ( 7.5 ; 95 % CI , 0.0 - 15.0 ; P = .04 ) than the control group . CONCLUSIONS Supervised treadmill training improved 6-minute walk performance , treadmill walking performance , brachial artery flow-mediated dilation , and quality of life but did not improve the short physical performance battery scores of PAD participants with and without intermittent claudication .  Lower extremity resistance training improved functional performance measured by treadmill walking , quality of life , and stair climbing ability .
