Targeted PEMF™ and Magnets: What’s the Difference?

Dec 18, 2014

magnets.jpgStatic magnets deliver a static (not time-varying) magnetic field and have been used in medicine for centuries. It is only recently that peer-reviewed clinical studies suggest that magnets could relieve pain. The Loop’s targeted PEMF signal also delivers a magnetic field, but this field is time-varying. Targeted PEMF has been shown in many peer-reviewed studies to reduce acute and chronic pain and inflammation, as well as to enhance healing.

Why are magnets and targeted PEMF different?   

Magnets induce a static magnetic field. A static magnetic field cannot induce an electric field. In contrast, targeted PEMF does induce a time-varying electric field. This causes a small time-varying current to flow through all tissue penetrated by the field. targeted PEMF fields directly affect cellular chemistry, ultimately enhancing the cascades of healing effects starting with nitric oxide (NO) signaling. The pulsing nature of targeted PEMF allows the dose to be well-regulated. Magnets apply a continuous magnetic field dose, which has not been shown to affect NO production.   

Dosimetry comparison    

The depth of penetration of any magnetic field into tissue is determined solely by the size of the magnet. The Loop produces a 7.5 inch diameter time-varying magnetic field, which has an effective depth of penetration of up to 4.5 inches on either side of the Loop.

Loop-treatment-field.pngStatic magnets are typically much smaller in diameter with consequent lower depth of penetration, even if several small magnets are placed side by side. The magnetic fields created by static magnets and the Loop travel through and past the skin (including hair or fur, casts and bandages) to penetrate soft tissue and bones; however, the volume of tissue able to be treated by the Loop is significantly larger.

The mechanism of action of the targeted PEMF signal produced by the Loop is well understood and has been confirmed with well-controlled laboratory findings and double-blind randomized clinical studies, all of which have helped to define the best therapeutic dose for the Assisi Loop. In contrast, reviews of basic and clinical studies carried out with static magnets  show varied results. The reason for this appears due to the lack of controlled dosimetry studies. Thus, static magnets ranging from a few Gauss to thousands of Gauss have been employed. There are no dose guidelines for static magnets, so therapeutic results are unpredictable.

"What strength magnetic field should I use?" and "How long should it be applied?" are questions that do not need to be asked when using the Loop. All the studies have been done and the answers are in. The result is the signal configuration used in the Loop has been shown to deliver predictable therapeutic outcomes.
