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 .
Home-based walking exercise intervention in peripheral artery disease: a randomized clinical trial.
IMPORTANCE Clinical practice guidelines state there is insufficient evidence to support advising patients with peripheral artery disease ( PAD ) to participate in a home-based walking exercise program . OBJECTIVE To determine whether a home-based walking exercise program that uses a group-mediated cognitive behavioral intervention , incorporating both group support and self-regulatory skills , can improve functional performance compared with a health education control group in patients with PAD with and without intermittent claudication . DESIGN , SETTING , AND PATIENTS R and omized controlled clinical trial of 194 patients with PAD , including 72.2 % without classic symptoms of intermittent claudication , performed in Chicago , Illinois between July 22 , 2008 , and December 14 , 2012 . INTERVENTIONS Participants were r and omized to 1 of 2 parallel groups : a home-based group-mediated cognitive behavioral walking intervention or an attention control condition . MAIN OUTCOMES AND MEASURES The primary outcome was 6-month change in 6-minute walk performance . Secondary outcomes included 6-month change in treadmill walking , physical activity , the Walking Impairment Question naire ( WIQ ) , and Physical and Mental Health Composite Scores from the 12-item Short-Form Health Survey . RESULTS Participants r and omized to the intervention group significantly increased their 6-minute walk distance ( [ reported in meters ] 357.4 to 399.8 vs 353.3 to 342.2 for those in the control group ; mean difference , 53.5 [ 95 % CI , 33.2 to 73.8 ] ; P < .001 ) , maximal treadmill walking time ( intervention , 7.91 to 9.44 minutes vs control , 7.56 to 8.09 ; mean difference , 1.01 minutes [ 95 % CI , 0.07 to 1.95 ] ; P = .04 ) , accelerometer-measured physical activity over 7 days ( intervention , 778.0 to 866.1 vs control , 671.6 to 645.0 ; mean difference , 114.7 activity units [ 95 % CI , 12.82 to 216.5 ] ; P = .03 ) , WIQ distance score ( intervention , 35.3 to 47.4 vs control , 33.3 to 34.4 ; mean difference , 11.1 [ 95 % CI , 3.9 to 18.1 ] ; P = .003 ) , and WIQ speed score ( intervention , 36.1 to 47.7 vs control , 35.3 - 36.6 ; mean difference , 10.4 [ 95 % CI , 3.4 to 17.4 ] ; P = .004 ) . CONCLUSION AND RELEVANCE A home-based walking exercise program significantly improved walking endurance , physical activity , and patient-perceived walking endurance and speed in PAD participants with and without classic claudication symptoms . These findings have implication s for the large number of patients with PAD who are unable or unwilling to participate in supervised exercise programs .
