Mechanisms of Action And Effects of Pulsed Electromagnetic Fields (PEMF) in Medicine (original) (raw)

In recent years many studies have demonstrated stimulatory effects of pulsed electromagnetic fields (PEMF) on biological tis-sue. However, controversies have also surrounded the research often due to the lack of knowledge of the different physical consequences of static versus pulsed electromagnetic. PEMF is widely used for treating fractures and non-unions as well as for treating diseases of the joints. Furthermore, new research has suggested that the technology can be used for nerve regener-ation and wound healing although conclusive clinical trials, besides those for fracture healing, are still lacking. Despite the apparent success of the PEMF technology very little is known regarding the coupling between pulsed electrical fields and bio-chemical events leading to cellular responses. Insight into this research area is therefore of great importance. In this review we describe the physical properties of PEMF-activated electrical fields and explain the typical set up for coils and p...

This pilot study was conducted to investigate whether multiple electrophysiological activities could be altered when exposed to extremely low frequency pulsed electromagnetic field (PEMF) over a consecutive 5 day period. Our results revealed substantial changes in electroencephalographic hemispheric asymmetry, observed at the theta band posterior predominance, an increase in the low frequency heart rate variability, changes in the surface skin temperature and skin bioelectric impedance fluctuations in its frequency spectrum. Due to the small sample size these results reveal no solid and conclusive evidence in the possible alterations in electrophysiological responses due to PEMF.
