Abstract

Purpose: The aim of this study was to evaluate the effect of functional low frequency electrical
stimulation of quadriceps and calf muscles on femoral blood flow in patients with chronic heart
failure (CHF).
Methods: Fifty patients with chronic heart failure (CHF) were randomly selected from Cairo
university hospital, their ages ranged from 40 to 60 years. They were divided into two groups,
thirty patients for study group, and twenty patients for control group. Each patient in the study
group received low frequency electrical stimulation with frequency 5 sessions per week for three
successive weeks, in addition to medical treatment. Each patient of the control group received
the same medical treatment, Pre and post study blood flow assessment was done for each patient
of both groups.
Results: The result of this study revealed statistically significant difference in femoral blood
flow that showed a statistically significant improvement in patients for the study group in
comparison to control group.
Conclusion: Functional low frequency electrical stimulation of quadriceps and calf muscles
improved femoral blood flow not only oxygen and nutrition also improve venous return without
volume over load on the cardiovascular system in patients with chronic heart failure, therefore
helped to decrease swelling, reduce pain and increase healing. FES may represent a practical and
effective strategy to improve perfusion and reduce risk of vascular complication. Thus we
recommend using functional electrical stimulation of quadriceps and calf muscles in order to
improve femoral blood flow in patients with chronic heart failure.
