Abstract:
A method for producing a real magnetic stimulation effect and a fake magnetic stimulation effect in a biological tissue, comprising:providing an electromagnetic means for inducing at least two electromagnetic fields in said biological tissue, in a real magnetic stimulation mode, energizing the electromagnetic means with predetermined pulsing power levels for simultaneously inducing in said biological tissue at least two electromagnetic fields oriented essentially codirectional with each other in a target area in order to obtain a mutually augmenting effect and to form a resultant electromagnetic field of sufficient magnitude for essentially exciting said biological tissue, and in a fake magnetic stimulation mode, energizing the electromagnetic means with substantially the same pulsing power levels as employed in the real magnetic stimulation mode for simultaneously inducing in said biological tissue at least first and second electromagnetic fields superimposed with each other and oriented with respect to each other in said target area in order to obtain a mutually cancelling effect and to form a resultant electromagnetic field of substantially lower magnitude than the resultant electromagnetic field formed in the real magnetic stimulation mode.
