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 .
Strength training increases walking tolerance in intermittent claudication patients: randomized trial.
OBJECTIVE To analyze the effects of strength training ( ST ) in walking capacity in patients with intermittent claudication ( IC ) compared with walking training ( WT ) effects . METHODS Thirty patients with IC were r and omized into ST and WT . Both groups trained twice a week for 12 weeks at the same rate of perceived exertion . ST consisted of three sets of 10 repetitions of whole body exercises . WT consisted of 15 bouts of 2-minute walking . Before and after the training program walking capacity , peak VO(2 ) , VO(2 ) at the first stage of treadmill test , ankle brachial index , ischemic window , and knee extension strength were measured . RESULTS ST improved initial claudication distance ( 358 + /- 224 vs 504 + /- 276 meters ; P < .01 ) , total walking distance ( 618 + /- 282 to 775 + /- 334 meters ; P < .01 ) , VO(2 ) at the first stage of treadmill test ( 9.7 + /- 2.6 vs 8.1 + /- 1.7 mL.kg(-1).minute ; P < .01 ) , ischemic window ( 0.81 + /- 1.16 vs 0.43 + /- 0.47 mm Hg minute meters(-1 ) ; P = .04 ) , and knee extension strength ( 19 + /- 9 vs 21 + /- 8 kg and 21 + /- 9 vs 23 + /- 9 ; P < .01 ) . Strength increases correlated with the increase in initial claudication distance ( r = 0.64 ; P = .01 ) and with the decrease in VO(2 ) measured at the first stage of the treadmill test ( r = -0.52 ; P = .04 and r = -0.55 ; P = .03 ) . Adaptations following ST were similar to the ones observed after WT ; however , patients reported lower pain during ST than WT ( P < .01 ) . CONCLUSION ST improves functional limitation similarly to WT but it produces lower pain , suggesting that this type of exercise could be useful and should be considered in patients with IC
