1. The active widening of the diameter ofblood vessels;
"Under the influence of magnetic fields the infrared thermogram clearly shows a steadily increasing energy radiation from the body originating in the blood vessels, continually becoming lighter in color and gradually covering the surrounding tissue, when observed on the monitor. Evidently, the dilatation of the blood vessels is the cause of this phenomenon."
"It is worthwhile noting:
(a) That a large blood vessel dilates as well as the nutritive capillaries of the periphery,
(b) That pulsating magnetic therapy applied to the head need the lowest induction intensity in order to achieve a reaction."
"A variation of the oxygen partial pressure is a direct consequence of a modified circulation in tissue by means of determined magnetic fields. Pulsating magnetic therapy with the above mentioned characteristics is able to increase rapidly the transcutaneously measured oxygen in the terminal tissue."
"Therefore the effect of a pulsed electromagnetic field is the result of the balance between the frequency of action potentials of the nerve and the hyper polarization by the frequency of Eddy currebts."
We believe also that pain caused by an acute or chronic oxygen deficiency due to small vascularization and blood flow with accumulation of mathabolits and transmitted by the sympathic nervous system can be reduced in the described way by pulsating magnetic therapy. We have discussed here only the pain reducing effect of magnetic fields, but I would like to mention at this point that magnetic fields also have a therapeutical effect in a great number of indications."
Clinical experiments show that pulsating magnetic therapy can reduce pain sensation immediately
