Design of coils driven by pulsed electromagnetic field generator and the effect of wound healing in rats

Chronic wound healing is an important problem especially in diabetic and the elderly which is needed development of the current treatment methods. Electromagnetic fields (EMF) has a significant impact on our body. These fields are being used for bone problems, cartilage regeneration, and pain removal for physiotherapy purposes. Lately, EMFs are often used in in vitro and in vivo assays. In this study, in vivo test results of the applied pulsed electromagnetic fields (PEMF) with our designed Helmholtz coil array system are given. The skin wound healing conducted in rats as an experimental model provides important information for evaluating the efficacy and mechanism of these kind of treatments. For this purpose, effectiveness of PEMF compared to control groups on experimental skin healing effect was examined macroscopically. Compared with the control groups a faster wound healing process was followed by PEMF application at 75 Hz frequency.
