Magnetic and copper bracelets have been popular for quite sometime now. They have become alternative therapies used by many people to treat pain caused by various musculoskeletal diseases, such as arthritis. But do they actually work? Researchers from the UK have shown in the first randomized placebo-controlled trial that these metallic objects are, in fact, ineffective in treating pain. They say that any benefit derived from them can be attributed to psychological placebo effects. “…our findings suggest that such devices have no real advantage over placebo wrist straps that are not magnetic and do not contain copper,” said Stewart Richmond, the lead author of the study. However, he emphasizes that although these products don’t necessarily cause harm, people should be careful about spending a lot of money on products that claim to cure your ailments with magnetic therapy. The study was published in the current issue of Complementary Therapies In Medicine. [via Medical News Today]

Research presented this week at an American Heart Association conference warns of the potential dangers headphones can impose on implanted pacemakers and defibrillators. In a study of 60 people with these devices researchers found when headphones were about an inch from the device, interference was detected nearly one-fourth of the time — in four of the 27 pacemaker patients and 10 of the 33 with defibrillators. A pacemaker even reset itself in one patient. This interference occurs whether the headphone is plugged in or not. The reason this happens is because headphones, especially small earbud types, contain neodymium, one of the most powerful and concentrated magnetic substances. Dr. Kenneth Ellenbogen, a heart device expert at Virginia Commonwealth University and a spokesman for the heart association, said the solution is simple: “Keep your headphones on your ears and when they’re not on your ears, you shouldn’t put them over your chest or your pacemaker.” Although headphones are still safe to use, in general it is a good idea to keep small electronics at least a few inches away from any implanted cardiac devices.
