Again, they tested the effectiveness of 4 months of treatment with magnetic insoles. The results showed that the insoles produced benefits beyond that of the placebo effect and reduced the severity of such symptoms as burning pain, numbness, tingling and exercise-induced pain. Multiple sclerosis 30 people with multiple sclerosis underwent a 2-month, double-blind, placebo-controlled study using a PEMP device. One thing you should remember is that the magnet s north pole is magnetically negative while the south is magnetically positive. You should use the north pole for body infections, alleviate pains from menstrual cycles, inflammations, for cold and accompanying symptoms and for scar tissue healing. The south pole, on the other hand, is best used for muscle strengthening, prostate problems, congestions and when one is pregnant. To date, these ailments include arthritis, Fibromyalgia, carpal tunnel syndrome, back pains, sciatica and general muscle aches and pains. Other diseases that magnet therapy is also known to give relief are diabetes, high blood pressure, high cholesterol, and hardened arteries. It also promotes sound sleep, calms the nerves, and assists the relief of drug addiction. Lengths of use The magnets need not be handled directly or touch the skin. It can be inside a bag, inside some wraps with the right poles facing the body. Strong magnets (those that can lift a kilo or more) may be used for one hour daily. Small or weak magnets may be left in place all day. Serious infections For serious infections, strong pain or cancerous tumors, even powerful magnets can remain in the body as long as they seem to be beneficial. There are studies who are trying to prove the benefits of magnets of arthritis. The studies are not that conclusive since the results showed improvement, the effects or the statistics are too minimal be considered significant like in the study published in the The New York Times in 2009 by Anahad O Conner. There are many theories regarding the sizes and types of magnets, how to use them, and where to apply them depending on the conditions and factors of being treated. Unipolar magnets Unipolar magnets have been known to have greater depth of magnetic penetration. Because of this, users feel they are more effective in treating deeper tissues.
