In order to answer your question I will give you some fo my experience with the MRS.
I have known for many years that since the early sixties NASA has upgraded the health of their astronauts by saturating space capsules/spacesuits with PEMF energy, I checked out their website as anyone can!
In October of 2007 I was invited to a meeting where Mediconsult performed a demonstration of PEMF energy which they call "Magnetic Resonance Stimulation" or MRS.
I tested it, was impressed, bought into it, and have since enjoyed very significant improvements in our health and happiness . Using the MRS 2000+ has been an energizing, rejuvenating and healing experience for us. The company Mediconsult hails from Germany and manufactures the MRS2000+ which is the latest ultramodern refinement of Pulsating field technology. This device is used by over 4000 world class and Olympic athletes in Europe and Asia. About 2 years ago Mediconsult became incorporated in the USA and Canada. Dr Oz [of Oprah Winfrey] has stated that the newest frontier in medicine is ENERGY medicine.
Heisenberg, the grandfather of modern physics, and Nobel prize recipient, has said that electromagnetic energy is "the elemental energy on which all life depends".
The approach is HOLISTIC in the sense that the focus is brought to bear on stimulating energy of the entire system to heal itself on both the mental AND physical levels. It is also completely "natural" in that it replaces the normal impulses we should be getting from the earth but are not because the natural field has weakened by about 50% in the last 300 years. Also there is now an endless array of interfering harmful impulses coming at us from cordless phones, microwave ovens, high tension wires, cell phones, cars etc. I have attached a number of educational links below.
The MRS strengthens the defense mechanism/immune sytem ,vitality by addressing broad parameters of health, IE Oxygenation and cellular stimulation, so that the body s ability to self heal is improved[refer link 7 below].
This method is as old as the earliest life forms on our planet, as it copies nature.
Link #2 shows the MRS 2000 + functioning in a clinical setting with Dr Neff.
Link #3 is a general informational, and link # 4 shows a series of peer reviewed studies, all of which can be Googled for veracity and some are done "double blind"!! This link is amazing to develop fully and study in depth!
Link #5 shows CTV news reporting on the use of pulsating fields for migraine headaches' and link#6 shows how NASA is still studying this area to increase the level of health of astronauts to prevent bone loss/muscle wasting, osteoporosis and other health issues. They have used this technology for over 40 years, and are now undretaking further research in connection with their plans to go to MARS.
With an annual budget of many billions they can afford the very best.
The last link  fully covers all aspects of PEMF therapy
I love using the MRS for family, friends,neighbours etc. I purchased the unit in Oct. 07 ,and by Feb. 08 I was sprinting for the first time in 8 years, also the energy level has increased enormously.
If you want to discuss further let me know, am dedicating some of my time to ensure people are aware of this!
