PEMF vs. IR for muscle spasm?: In my experience, PEMF works better for me. Some people disagree. Individual responses vary. People are different.
Catalyst effect of PEMF shown on MRI or CT?: I have run experiments and published images and CT data showing extensive and accelerated bone repair. These experiments were carried out at Texas A&M Vet School:
These experiments contributed significantly to our understanding of the effective pulse waveform and dose-response, but they do not and were not designed to determine a “catalyst effect”, which I take to mean the “underlying biophysical mechanisms”, which, for PEMF, remain unknown, marketing fraud and claims to the contrary notwithstanding.
Why not start with maximum intensity: Many reasons, most notably:
Most people do not respond best to maximum intensity. As we teach our children: too much is too much. Most people (~95%) respond best, as we advise, to intensity settings of “M” or “H”, and some have a less effective response to “X” intensity. Only a small percentage need to use full intensity. And using common sense, it is like an automobile: it is not “best” or “most effective” to drive everywhere at full speed.
In fact, once you have the coils placed properly the number one way to improve the effectiveness of ICES-PEMF is to turn down the intensity if you have been using it at full power without much benefit. At least 90% of people who report that they do not get a positive benefit from full power report that, if they turn down the intensity, their benefit is greater.
Bumps toward or away from skin? This is so that people who do not have a degree in physics can use the device correctly. Magnetism is very counter-intuitive and difficult to understand. I have worked through all of the calculus, done all of the tests, and if you follow my directions then I can assure you that the magnetic fields will be correctly aligned.
So, if you follow my directions (bumps away from the skin) the magnetic pulses will be correctly aligned. If you do not follow my directions, they might be OK, they might not, and it is impossible to say unless what you are trying has been tested extensively and verified.
