July 29, 2015 updated by: giti torkaman, Tarbiat Modarres University

The Effect of Electrical Stimulation on the Expression of VEGF, VEGFR-2, HIF and NO in the Diabetic Foot Ulcer

The purpose of this study is to determine whether electrical stimulation is effective in the expression of VEGF, VEGFR-2, HIF-1α and NO and healing in diabetic foot ulcer.

Detailed Description

30 type 2 diabetic patients with ischemic foot ulceration were enrolled. Patients were randomly assigned to electrical stimulation (ES, n=15) or sham ES (placebo, n=15) groups. ES group received cathodal direct current for 1 h/day, 3 days/week, for 4 weeks (12 sessions). Wound fluid sample was collected for VEGF, VEGFR-2, HIF-1α and NO measurement in the first and last treatment sessions before and after intervention. Wound surface area (WSA) was measured at 1st, 6th, and 12th session.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Electrical stimulation
In the electrical stimulation group, group who received direct current ES at sensory threshold intensity for 1 h/day, 3 days/week, for 4 weeks (12 sessions)
Procedure: Electrical Stimulation
Direct current with sensory intensity for one hour
Other Names:
  • Direct current ES
Placebo Comparator: Placebo
In the placebo group, the treatment procedure was the same as that the ES group, but the current intensity was zero
Procedure: Placebo
Direct current with zero intensity for one hour
Other Names:
  • Placebo Direct current ES
