Electromagnetic pulses can significantly reduce pain and inflammation for osteoarthritis sufferers, according to new research .

Fred Nelson, MD and his colleagues at the Henry Ford Hospital in Detroit,Michigan investigated 34 patients who wrapped a small, battery-operated devicearound their knees that emitted a low-intensity, pulsating, electromagneticfrequency. They did this for 15 minutes twice each day for six weeks. Somepatients were given placebo devices that were similar, but did not function. Reportedly, more than 40 percent of these users experienced pain relief on the first day. Thefindings are being presented this week at the 56^th Annual Meeting ofthe Orthopaedic Research Society in New Orleans.

“Our results show pulsed electromagnetic fields caused a significant decrease in pain,” Nelson stated.

According to Dr. Nelson, electromagnetic signals have been shown in laboratory environments to decrease calcium in cartilage cells, setting off a series of chemical events that can lead to reduced inflammation.

Nelson added that one of the advantages to the electromagnetic approach is alack of side effects. He mentioned it also offers lower long-term costs and immediate pain relief.

"We look at electromagnetic pulses as a potential way to improve quality of life and independence for those who suffer from osteoarthritis ofthe knee,” adds Dr. Nelson.

Osteoarthritis of the knee is a leading cause of disability and loss of independence. It is a slow, progressively degenerative disease in which the joint cartilage gradually wears away due to trauma, aging or infection. As the cartilage thins, the surrounding bone thickens and often bones rub against one another, causing additional wear. Normal activity becomes painful and difficult.

Current treatments include drug therapies like anti-inflammatory medication orpain relievers; physical therapy; support devices; health and behavioral modifications such as weight loss; surgery and joint replacement, adds Dr. Nelson.

Dr. Nelson explains that medications often have variable success and can produce considerable side effects such as changes in kidney and liver function,a reduction in the ability of blood to clot as well as abdominal pain, nausea and indigestion.
Dr. Nelson says researchers will continue to look at the consistency of the relief, how long the pain relief lasts and if electromagnetic pulses might affect other joints.
