AUTHORS ' CONCLUSIONS SET has statistically significant benefit on treadmill walking distance ( maximal and pain-free ) compared with non-supervised regimens .
BACKGROUND Although supervised exercise therapy is considered to be of significant benefit for people with leg pain ( peripheral arterial disease ( PAD ) ) , implementing supervised exercise programs ( SETs ) in daily practice has limitations .

Intermittent claudication: clinical effectiveness of endovascular revascularization versus supervised hospital-based exercise training--randomized controlled trial.
PURPOSE To compare clinical success , functional capacity , and quality of life during 12 months after revascularization or supervised exercise training in patients with intermittent claudication . MATERIAL S AND METHODS This study had institutional review board approval , and all patients gave written informed consent . Between September 2002 and September 2005 , 151 consecutive patients who presented with symptoms of intermittent claudication were r and omly assigned to undergo either endovascular revascularization ( angioplasty-first approach ) ( n = 76 ) or hospital-based supervised exercise ( n = 75 ) . The outcome measures were clinical success , functional capacity , and quality of life after 6 and 12 months . Clinical success was defined as improvement in at least one category in the Rutherford scale above the pretreatment level . Significance of differences between the groups was assessed with the unpaired t test , chi(2 ) test , or Mann-Whitney U test . To adjust outcomes for imbalances of baseline values , multivariable regression analysis was performed . RESULTS Immediately after the start of treatment , patients who underwent revascularization improved more than patients who performed exercise in terms of clinical success ( adjusted odds ratio [ OR ] , 39 ; 99 % confidence interval [ CI ] : 11 , 131 ; P < .001 ) , but this advantage was lost after 6 ( adjusted OR , 0.9 ; 99 % CI : 0.3 , 2.3 ; P = .70 ) and 12 ( adjusted OR , 1.1 ; 99 % CI : 0.5 , 2.8 ; P = .73 ) months . After revascularization , fewer patients showed signs of ipsilateral symptoms at 6 months compared with patients in the exercise group ( adjusted OR , 0.4 ; 99 % CI : 0.2 , 0.9 ; P < .001 ) , but no significant differences were demonstrated at 12 months . After both treatments , functional capacity and quality of life scores increased after 6 and 12 months , but no significant differences between the groups were demonstrated . CONCLUSION After 6 and 12 months , patients with intermittent claudication benefited equally from either endovascular revascularization or supervised exercise . Improvement was , however , more immediate after revascularization
