Abstract
COLLINS and co-workers, Research and Development Service, College of Nursing at University of Illinois Chicago, Chicago, IL 60141, USA, eileen.collins@med.va.gov, have conducted a trial of PoleStriding exercise and vitamin E in the management of peripheral vascular disease.
Background
The aim of this study was to evaluate the effects of PoleStriding, a form of exercise similar to cross-country skiing, and also of vitamin E, on the walking ability, quality of life, and claudication pain of patients with peripheral arterial disease.
Methodology
52 patients were randomized to 4 groups: PoleStriding and vitamin E; PoleStriding and placebo; vitamin E only; placebo only. Assignment to vitamin E or placebo was double-blinded. Exercise as three times weekly for 30 to 45 minutes. Vitamin E was given at 400 IU daily.
Results
PoleStriding significantly (p = 0.001) improved exercise tolerance. Ratings of claudication pain were decreased (p = 0.02). In contrast, vitamin E had no effect on leg pain or exercise tolerance. Physical functioning improved in the exercise groups only.
Conclusion
PoleStriding effectively improved exercise tolerance and quality of life in patients with peripheral arterial disease, whereas vitamin E supplementation does not seem to confer any worthwhile benefits.
