HOW IMPORTANT IS THE WAVEFORM IN PEMF?

Transcript: I probably should also talk about waveform because one of the key things that people who market magnetic systems talk about is the waveform. I’m not convinced that the particular waveform is all that important. What is important about the wave is how fast it reaches a peak and how long that peak lasts. So if you have a wave that’s a square wave, when it goes up, it’s producing most of the benefit. If it goes across and does nothing, there’s no further change in the wave, it’s not doing Faraday’s law, you’re getting nothing, no benefit. So the longer it stays up there, the less benefit you get for the amount of stimulation time.

Then when it drops off, you get some benefit as well because it’s now moving out of the body and interacting with the tissues on the way out. But the force of the magnetic field coming out is not as powerful as the force of the magnetic field going in the upstroke, because the upstroke is usually faster than a downstroke.  You get different actions and different benefits. 

Sawtooth waves give you an upstroke, a little downstroke, and another little upstroke.  That second little upstroke gives you a little bip in energy, but it’s still not as good as having a very high DB/DT. You can almost never duplicate a 70 Gauss intensity magnetic field with a rapid rise time with a very low-intensity field, it’s almost impossible from an engineering perspective. But you could design any waveform to maximize the DB/DT for that waveform. That’s the science of it. 

What I’m saying is that for the most part waveforms are not important. If the researchers or the producers of the magnetic systems would tell you what their DB/DT was, then we could compare devices.  Almost no manufacturers give you that number because it’s hard to define. Most of the time these numbers are theoretical. If you do measurements using magnetometers, they have to be scientifically very, very precise machines to do the measurements.  The magnetometer has to be designed for that particular signal to give you specificity, to tell you exactly what that signal is doing. That’s why it’s very hard to compare these magnetic systems. So I discount the claims that anybody makes that their system is better than somebody else’s because of the waveform. The science just doesn’t really hold up.
