OBJECTIVES Our goal was to determine whether an exercise programme was effective in alleviating symptoms and increasing walking treadmill distances and walking times in people with intermittent claudication .
Secondary objectives were to determine whether exercise was effective in preventing deterioration of underlying disease , reducing cardiovascular events , and improving quality of life .
A pilot exercise intervention to improve lower extremity functioning in peripheral arterial disease unaccompanied by intermittent claudication.
PURPOSE A pilot study was conducted to test the feasibility of supervised treadmill exercise training to improve functioning in study participants with peripheral arterial disease who did not have classical symptoms of intermittent claudication . METHODS For this study , 32 men and women with peripheral arterial disease but no symptoms of claudication were r and omized to exercise training or usual care .  The intervention was a 12-week supervised treadmill walking program . Outcomes included 6-minute walk distance , maximum treadmill walking distance , and 4-meter walking velocity . Participant-reported community walking ability was measured with the Walking Impairment Question naire ( WIQ ) . Inflammatory blood factor levels also were measured . RESULTS Altogether , 25 participants who completed follow-up testing were included in intention-to-treat analyses . Of 24 participants ( 58 % ) r and omized to exercise , 14 completed the entire exercise training program . The participants r and omized to the intervention showed greater improvement in their WIQ walking speed score than the control subjects ( P = .05 ) . The participants r and omized to the intervention showed improvements in their 6-minute walk distance ( 1134 + /- 347 vs 1266 + /- 295 feet ; P = .03 ) , maximal treadmill walking distance ( 389 + /- 248 vs 585 + /- 293 feet ; P < .001 ) , WIQ distance score ( 52.3 + /- 29.1 vs 63.1 + /- 25.1 ; P = .002 ) , and WIQ speed score ( 48.7 + /- 26.8 vs 59.7 + /- 22.7 ; P = .008 ) . The participants r and omized to the control condition showed improvements in maximal treadmill walking distance ( 362 + /- 180 vs 513 + /- 237 feet ; P = .014 ) . There were no significant changes in the inflammatory blood factors after exercise . CONCLUSIONS This pilot study demonstrated that a supervised treadmill walking program may be feasible and may improve functioning for individuals with peripheral arterial disease who do not have classical symptoms of intermittent claudication . Further study is needed with a larger sample to identify optimal exercise methods that improve lower extremity functioning in men and women with peripheral arterial disease who do not have intermittent claudication
