Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Benefits of exercise for claudication

    Researchers from Northwestern University, in Chicago studied the effects of treadmill exercise and resistance training.

    First, the details.

    • 156 patients with peripheral arterial disease (PAD) were randomly assigned to 1 of 3 groups.
      • Supervised treadmill exercise
      • Lower extremity resistance training
      • Control group
    • Some of the patients also had intermittent claudication.

    And, the results.

    • For the 6-minute walk, the supervised treadmill exercise group significantly increased the distance walked by 36 meters (118 feet) vs the control group.
      • There was no improvement with resistance training vs the control group.
    • Neither exercise group improved its short physical performance battery scores.
    • Brachial artery flow-mediated dilation improved significantly in the treadmill group vs the control group.
    • The treadmill group had significantly greater increases in maximal treadmill walking time, walking impairment distance score, and physical functioning score (SF-36) vs the control group.
    • The resistance training group had significantly greater increases in maximal treadmill walking time, walking impairment scores for distance, and stair climbing vs the control group.

    The bottom line?
    Summing up, supervised treadmill training leads to improved walking, vascular improvements, and better quality of life in people who have PAD with and without intermittent claudication.

    Lower extremity resistance training improves walking, quality of life, and stair climbing ability.
