The purpose of this study is to examine the effect of age and the effect of exercise intensity of rehabilitation programs on claudication pain symptoms and leg circulation of younger and older patients with intermittent claudication.

Condition Intervention
Intermittent Claudication
Behavioral: Walking Exercise

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Further study details as provided by National Institute on Aging (NIA):

Primary Outcome Measures:
  • Change in the walking distance to onset of leg pain, and the change in walking distance to maximal leg pain. [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Changes in cardiopulmonary function, calf muscle circulation, and health-related quality of life. [ Time Frame: 6 months ]

Enrollment: 64
Study Start Date: February 1994
Study Completion Date: January 2000
Primary Completion Date: January 2000 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Low intensity group (40% of maximal exercise capacity)
Behavioral: Walking Exercise
Intermittent treadmill walking to near maximal claudication pain three days per week
Experimental: 2
High intensity group (80% of maximal exercise capacity)
Behavioral: Walking Exercise
Intermittent treadmill walking to near maximal claudication pain three days per week

Detailed Description:
Thirty-one patients randomized to low-intensity exercise rehabilitation and 33 patients randomized to high-intensity exercise rehabilitation completed the study. The 6-month exercise rehabilitation programs consisted of intermittent treadmill walking to near maximal claudication pain three days per week at either 40% (low-intensity group) or 80% (high-intensity group) of maximal exercise capacity. Total work performed in the two training regimens was similar by having the patients in the low-intensity group exercise for a longer duration than patients in the high-intensity group. Measurements of physical function, peripheral circulation, and health-related quality of life were obtained on each patient before and after the rehabilitation programs.

Ages Eligible for Study:   45 Years to 90 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • History of intermittent claudication
  • Exercise tolerance limited by intermittent claudication during a screening treadmill test

  • Live independently at home

Exclusion Criteria:

  • Absence of PAD (peripheral artery disease)
  • Asymptomatic PAD (Fontaine stage I)
  • Rest pain PAD (Fontaine stage III)
  • Exercise tolerance limited by factors other than claudication (e.g., coronary artery disease, dyspnea, poorly controlled blood pressure)
  • Active cancer, renal disease, or liver disease
  • Current use of pentoxifylline or cilostazol medications for the treatment of intermittent claudication
