[The effects of different types of pulsed electromagnetic fields on fibroblast cell cultures].
The aim of this study is to determine which is the most effective pulsed electromagnetic field (PEMF) on a fibroblastic culture cells.


METHODS
Five different types of PEMF are generated by a pulsed generator created by the author. The electric signal, received by a reference coil is pulse bursts type. The growth rate of a fibroblastic culture cells is measured with and without different types of PEMF.


RESULTS
Comparative results showed the the most effective type of PEMF is characterized by a 15 mV positive amplitude of the signal and a 15 Hz frequency of the bursts. The intermittent stimulation (8 hours/day) was more effective than continuous stimulation.
