CONCLUSION Exercise therapy increases the PWD and AWD  in patients with intermittent claudication .
Supervised exercise therapy increases the PWD and AWD more than st and ard care .
OBJECTIVE To review the evidence for the effectiveness of exercise therapy and to estimate the additional effect of supervision on exercise therapy in patients with intermittent claudication .
Exercise rehabilitation improves functional outcomes and peripheral circulation in patients with intermittent claudication: a randomized controlled trial.
OBJECTIVE To determine the effects of a 6-month exercise program on ambulatory function , free-living daily physical activity , peripheral circulation , and health-related quality of life ( QOL ) in disabled older patients with intermittent claudication . DESIGN Prospect i ve , r and omized controlled trial . SETTING University Medical ( Center and Veterans Affairs Medical Center , Baltimore , Maryl and . PARTICIPANTS Thirty-one of 61 patients with Fontaine stage II peripheral arterial occlusive disease ( PAOD ) were r and omized to  exercise rehabilitation and 30 to  usual-care control . Three patients from the exercise group and six patients from the control group dropped out , leaving 28 and 24 patients , respectively , completing the study in each group . INTERVENTION Six months of exercise rehabilitation . MEASUREMENTS Treadmill distance walked to onset of claudication and to maximal claudication , ambulatory function , peripheral circulation , perceived QOL , and daily physical activity . RESULTS Compliance with the exercise program was 73 % of the possible sessions . Exercise rehabilitation increased treadmill distance walked to onset of claudication by 134 % ( P < .001 ) and to maximal claudication by 77 % ( P < .001 ) , walking economy by 12 % ( P = .003 ) , 6-minute walk distance by 12 % ( P < .001 ) , and maximal calf blood flow by 30 % ( P < .001 ) . Changes in distance walked to maximal pain correlated with changes in walking economy ( r = -.50 , P = .013 ) and changes in maximal calf blood flow ( r = .38 , P = .047 ) . Exercise rehabilitation increased accelerometer-derived daily physical activity by 38 % ( P < .001 ) ; this change correlated with the change in distance walked to maximal pain ( r = .45 , P = .020 ) . These improvements were significantly better than the changes in the control group ( P < .05 ) . CONCLUSION Improvements in claudication following exercise rehabilitation in older PAOD patients are dependent on improvements in peripheral circulation and walking economy . Improvement in treadmill claudication distances in these patients translated into increased accelerometer-derived physical activity in the community , which enabled the patients to become more functionally independent
