Exercise for Women With Peripheral Arterial Disease

This study has been completed.

Collaborator:
Oklahoma Center for the Advancement of Science and Technology
Information provided by (Responsible Party):
Andrew Gardner, University of Oklahoma
ClinicalTrials.gov Identifier:
NCT01241747
First received: November 15, 2010
Last updated: March 23, 2017
Last verified: March 2017
  Purpose

Hypothesis #1. Supervised exercise rehabilitation will result in greater increases in exercise performance, peripheral vascular function, and health-related quality of life than compared to the attention-control group.

Hypothesis #2. The change in peripheral vascular function will be predictive of improved exercise performance following the supervised exercise program.

  • Change in 6-minute walk distance [ Time Frame: 3 months ]

Secondary Outcome Measures:
  • Change in calf muscle oxygen saturation [ Time Frame: 3 months ]
  • Change in daily ambulatory activity [ Time Frame: 3 months ]
  • Change in walking economy [ Time Frame: 3 months ]
  • Change in peak oxygen uptake [ Time Frame: 3 months ]

Enrollment: 33
Study Start Date: July 2009
Study Completion Date: March 2016
Primary Completion Date: March 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Supervised Exercise
Supervised program consisting of graded treadmill walking, with progressive increments in exercise duration from 15 to 40 minutes at an exercise intensity of 40% of exercise capacity.
Behavioral: Walking Exercise
3 times per week for 3 months
Active Comparator: Control
Light resistance training without any walking
Behavioral: Control
Resistance training 3 times per week for 3 months

  Eligibility

Ages Eligible for Study:   60 Years to 100 Years   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • women 60 years of age and older having a 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
  • an ankle/brachial index (ABI) < 0.90 at rest or < 0.73 immediately following the treadmill exercise test
  • at least one year past menopause

Exclusion Criteria:

  • 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.)
  • use of medications indicated for the treatment of intermittent claudication (cilostazol and pentoxifylline) initiated within three months prior to investigation)
  • cognitive dysfunction (mini-mental state examination score < 24)
  • active cancer, renal disease, or liver disease
  • a calf skin fold measurement > 50 mm, because of potential interference with the light path of the near-infrared spectroscopy probe from penetrating the subcutaneous tissue
  • pulse arterial oxygen saturation of the index finger < 95% because of the potential deleterious effect on calf muscle StO2 from poor pulmonary gas exchange
