简要总结
The purpose of this study is to examine the effects of a home-based exercise rehabilitation program compared to a supervised exercise program on intermittent claudication (leg pain or discomfort) and ambulatory function.
详细描述
This study seeks to 1) compare the changes in ambulatory function, vascular function, and health-related quality of life in patients limited by intermittent claudication following a home-based exercise rehabilitation program, a supervised exercise program, and a light resistance training exercise program; and 2) determine whether changes in walking efficiency, calf muscle circulation, and calf muscle oxygen are the reasons by which both home-based and supervised exercise rehabilitation improve ambulatory function.
We hypothesize that a home-based exercise program utilizing new physical activity monitoring technology that can accurately quantify exercise adherence as well as the intensity, duration, and volume of exercise sessions will result in similar changes in ambulatory function, vascular function, and health-related quality of life compared to a standard, supervised exercise program. Further, both the home-based and supervised exercise rehabilitation programs will result in greater changes in ambulatory function, vascular function, and health-related quality of life than a light resistance training exercise program. Finally, we hypothesize that the changes in walking efficiency, calf muscle circulation, and calf muscle oxygen will each be predictive of improved ambulation following the home-based exercise program as well as the supervised exercise program.
The 3-month program will consist of walking 3 times per week, with progressive increases in duration and intensity. The two walking exercise programs will be matched on the estimated caloric expenditure during the training sessions. Patients in the control group will perform light resistance training without any walking exercise.

- •Rest pain due to PAD (Fontaine stage III)
- •Tissue loss due to PAD (Fontaine stage IV)

研究组 & 干预措施
1
Home-based program with progressive increases in exercise duration and intensity (i.e., cadence); walking duration will be longer for the home-based group because the intensity of walking will be lower than the graded treadmill walking performed by the supervised group
干预措施: Walking Exercise (Behavioral)
2
Supervised program consisting of graded treadmill walking, with progressive increments in exercise duration from 15 to 40 minutes, and progressive increments in exercise intensity from 50 to 70% of exercise capacity
干预措施: Walking Exercise (Behavioral)
3
Light resistance training without any walking exercise
干预措施: Control--Resistance Training (Behavioral)

次要结局
- Change in walking efficiency(3 months)
- Change in calf muscle circulation and calf muscle oxygen(3 months)
