NCT00618670

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in the walking distance to onset of leg pain, and the change in walking distance to maximal leg pain

    3 months

Secondary Outcomes (3)

  • Change in walking efficiency

    3 months

  • Change in calf muscle circulation and calf muscle oxygen

    3 months

  • Change in health-related quality of life

    3 months

Study Arms (3)

1

EXPERIMENTAL

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

Behavioral: Walking Exercise

2

EXPERIMENTAL

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

Behavioral: Walking Exercise

3

ACTIVE COMPARATOR

Light resistance training without any walking exercise

Behavioral: Control--Resistance Training

Interventions

Three times per week for 3 months

Eligibility Criteria

Age35 Years - 100 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Positive history of intermittent claudication assessed by the San Diego Claudication Questionnaire
  • Exercise limited by intermittent claudication during a screening treadmill test using the Gardner protocol
  • Ankle/brachial index (ABI) less than 0.90 at rest, which decreases to less than 0.73 immediately following the treadmill exercise test

You may not qualify if:

  • Absence of PAD (peripheral artery disease)
  • Asymptomatic PAD (Fontaine stage I)
  • Rest pain due to PAD (Fontaine stage III)
  • Tissue loss due to PAD (Fontaine stage IV)
  • Medical conditions that are contraindicative for exercise according to the American College of Sports Medicine (e.g., acute myocardial infarction, unstable angina, etc.)
  • Cognitive dysfunction (mini-mental state examination score less than 24)
