Blood flow is an important factor which can affect the repair and healing of injured tissues. There are many factors that may affect the blood flow. Electrical stimulation has been showed to produce long term changes in vascularization at the capillary level. This study was done to investigate the influence of microcurrent electrical stimulation (MES) on blood flow in normal subjects. Thirty healthy participants with mean age (28.77 ± 3.501) years, and the mean value of their body mass index was (23.20 ± 1.332) kg/m. Participants were assigned randomly into two equal groups; group (A) received high frequency MES with 125 Hz frequency for 30 min. while, group (B) received low MES with frequency 40 Hz for 30 min. All participants in both groups were assessed for resistivity Index, Total blood flow volume, mean blood flow velocity and peak systolic velocity by using ultrasonic doppler before and immediately after microcurrent application. Microcurrent electrical stimulation showed statistical significant improvement in blood flow resistivity index, total blood flow volume, mean blood flow velocity and peak systolic velocity in posterior tibial artery of normal healthy subjects, with significant statistical difference by using high frequency versus low frequency. The study revealed that both high frequency and low frequency microcurrent electrical stimulation were effective for improving the blood flow on the posterior tibial artery in normal healthy subjects
