Wow, this an interesting thread.
I may contribute a thing. I inspected a PEMF full body mat system. Doing some analysis I discovered that the Mat uses at 64 Hz base frequency using a basic sawtooth and bursts/packets of the 64 Hz signal followed by pauses. The frequency pattern of 64Hz signal bursts and pauses are varied over the day to resemble the brain frequencies.
The local applicators use a 30 KHz square signal in burst of some milliseconds followed by pauses and subsequent burst periods following a larger pause. Signals are unipolar and polarity is reversed all several minutes.
Using a Gaussmeter I could determine, that the T/s per pulse (both medium setting) seems to be lower than at the the M1 - and that from a 230V powered device.
The results of this product are mixed for me. Its good to relax (mat) but the applicators to not have the effect in regard of pain and suspected inflammation like the M1.
What I think to be an issue is the of 30 KHz for the “Spot” applicators. I think, this is not anymore a real PEMF “frequency”. May be that is the reason the effects are, for me, much less than from a M1 at Powerlevel 9 and B5-C5. Also the T/s per single 30 KHz pulse have to be estimated dramatically lower than on an ICES.
Does some here have an opinion about this?
