Scientific Literature Covering Varies Impulse Forms – Wave/Signal Forms
The typical shape of a frequency is a sine (sinus) wave. A sine wave is pre-specified, but can also appear in completely different forms by varying the electrical impulse. The form of the magnetic impulse is decisive in terms of the effectiveness of the signal. Take an ocean wave for example: An even, round wave (sine wave) tends to subside without delivering any force, whereas a wave which is virtually vertical can transfer all its energy (rectangular or square wave).
Rectangular impulses (square wave) have, e.g. a steep ascending and descending phase with the result that they transfer a great deal of force. This results that certain channels in the cell membrane are opened more quickly for necessary ion exchange within the cells.
The most critical value of the wave form is its rise and fall time. According to Liboff the therapeutic value of a given pulsed signal is highly dependent on how rapidly the rise time and fall time happen. This signal characteristic cannot be underemphasized, and is perhaps the most important parameter of an electromagnetic signal used during magnetic resonance stimulation (MRS).
One of the most useful wave forms created is the “saw-tooth” wave. Therefore, newer “logical” systems preferably use rectangular impulses, and/or so-called sawtooth impulses which are especially effective. By the way, sawtooth waves are a combination between a triangular, rectangular and sine waves. Both the saw-tooth signal shape and the square waveform have rise and fall times that are far more abrupt than a simple sine waveform, resulting in much greater biological effects.
All iMRS devices come with a whole body mat applicator offering the sawtooth impulse, and two local applicators offering the square wave. Unlike simple sine waves or static, externally worn magnets, the sawtooth electromagnetic signal changes continuously, producing constant induction of electromagnetism in the body’s tissues, maximizing ion displacement and preventing cellular membrane fatigue. This means that the cell membrane remains responsive to the signals, maximizing the beneficial effects of electromagnetic stimulation.
