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

    This blog ran from 2006 to 2016 and was 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.

    Supervised vs home exercise to treat intermittent claudication

    Intermittent claudication is a diagnosis for muscle pain (ache, cramp, numbness, or sense of fatigue) typically in the calf muscle, which occurs during exercise and is relieved by a short period of rest.

    Researchers at Oklahoma University Health Sciences Center, in Oklahoma City, compared home-based exercise to a supervised exercise program.

    First, the details.

    • 119 patients were randomly assigned to a treatment group.
      • Home-based exercise: intermittent walking to nearly maximal claudication pain for 12 weeks
      • Supervised exercise: as above but supervised
      • Usual-care
    • Patients wore a step activity monitor during each exercise session.
    • Claudication onset time and peak walking time obtained from a treadmill exercise test were recorded as the primary outcomes.
    • Daily ambulatory cadences (measure or beat of movement) measured during a 7-day period were also recorded.

    And, the results.

    • Adherence to home-based and supervised exercise was similar and exceeded 80%.
    • Both exercise programs significantly delayed claudication onset time and increased peak walking time.
    • Only home-based exercise increased daily average cadence significantly.
    • There were no changes in the usual care group.

    The bottom line?

    The authors concluded, “A home-based exercise program… has high adherence and is efficacious in improving claudication measures similar to a standard supervised exercise program. Furthermore, home-based exercise appears more efficacious in increasing daily ambulatory activity in the community setting than supervised exercise.”

    The authors tell us this is the first well-designed study to compare supervised vs home exercise for intermittent claudication. The findings suggest reconsidering the role of supervised exercise in these patients.
