Electric stimulation will accelerate wound healing

Researchers from the University of Manchester, together with Oxford BioElectronics, are working on a new method that could significantly speed up wound healing. It could help in the faster treatment of patients after surgery and accelerate the recovery of athlete injuries.

Technological progress has made treatment of patients today much simpler and more effective than decades ago. And ongoing research brings new inventions that can further improve this process. The latest idea is being developed by researchers at the University of Manchester, in collaboration with Oxford BioElectronics and is concerned with accelerating wound healing by electrostimulation of wounded areas.

A recent 40 volunteer test gave very promising results. Each patient had an identical wound on both arms. The left was treated in the traditional way, while in the right case a small electrical impulse was used, which was applied four times over a period of two weeks. These pulses stimulate a process called angiogenesis that accelerates the formation of new blood vessels and leads to increased blood flow to the damaged area. After 10 days, the wound was much smaller and deeper than this treated in the normal way, so it healed much faster. You can see this very accurately in the image below.

Ardeshir Bayat, head of the study, says the new method may be particularly useful for treating chronic wounds but also for any other type of lesion, much faster putting the patient on foot.
