According to research 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 under emphasized, and is perhaps the most important thing to note in an electromagnetic signal. An abrupt fall time represents a high peak voltage value, which is responsible for ion displacement in the body. The greater the ion displacement, the stronger the biological effect it exerts and is therefore more effective than a simple sine wave, or a static magnet. The waveform, or shape of the electromagnetic signal, is something to which very close attention needs to be paid. One of the most useful waveforms created is the “saw-tooth” wave. Research has shown that the saw-tooth carrier waveform provides the best magnetic resonance stimulation of all the waveforms. The sharp rise time and fall time produce the maximum impulse or stimulation to the cells, recharging them in the most powerful way. Unlike simple sine waves or static, externally worn magnets, the saw-tooth electromagnetic signal changes continuously, producing constant induction of electromagnetism into 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.
