Effects of treadmill training on walking distance and lower limb blood flow in patients with intermittent claudication
Journal Title: Rehabilitacja Medyczna - Year 2005, Vol 9, Issue 1
Abstract
Background: In patients with intermittent claudication treadmill training improves their walking ability. While the benefits of an exercise rehabilitation programme are recognized, the mechanisms involved are not completely appreciated. The improvement in lower limb blood flow may by one of the mechanisms leading to the increase in walking distance. In the present study arterial blood flow in lower limb as well as walking distance were assessed before and after supervised pain-free treadmill training. Methods: Eighty patients with peripheral arterial occlusive disease (stage II according to Fontaine) were randomised into the treadmill program or to the control group. Patients in the exercising group participated for 3 months 3 times a week in supervised treadmill trainings. Each session consisted of 3 cycles, each amounting to 85% of the pain-free walking distance. Changes in arterial blood flow and the onset of claudication pain were assessed in both groups.Results: After 12 weeks of the treadmill training lower limb blood flow in exercising group significantly improved (p<0.05). Painfree walking distance was prolonged by 119,6% in the exercising group and only 16.9% in the control group. Those changes were statistically significant in both groups (p<0.05).Conclusion: The results indicate that exercise training program using intermittent walking to 85% of the onset of claudication pain leads to a significant improvement in lower limb blood velocity and increase in pain-free walking distance.
