Electromagnetic pulses provide pain relief for osteoarthritis

08.03.2010
Electromagnetic pulses significantly decrease pain and inflammation associated with osteoarthritis of the knee, according to Henry Ford Hospital researchers.

In the double-blind, randomized placebo-controlled study, 34 patients used a portable battery-operated device that emits a low-intensity pulsating electromagnetic frequency and experienced more than 40 percent pain relief on their first day.

"Our results show pulsed electromagnetic fields caused a significant decrease in pain" says Fred Nelson, M.D., associate program director for research and director of the Osteoarthritis Center, Department of Orthopaedics, Henry Ford Hospital.

Dr. Nelson will present the results this week at the Orthopaedic Research Society's annual meeting in New Orleans.

Dr. Nelson explains that in the laboratory, electromagnetic signals have been shown to decrease calcium in cartilage cells. This sets off a series of chemical events that can lead to reduced inflammation. Previously, the electromagnetic fields have been used to control pain related to cosmetic surgery.

"We are really fine-tuning what we are doing to the cell environment with a very specific pulse sequence and frequency," says Dr. Nelson.

Patients strapped the small, ring-shaped plastic device around their knees for 15 minutes, twice daily for six weeks. The device was lightweight and patients could position the device directly over clothing. All participants were given a device with a coil that appeared to work but some were assigned active coils and others were given non-active coils. The electromagnetic device was developed by Ivivi Health Sciences of Montvale, New Jersey.

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 or pain relievers; physical therapy; support devices; health and behavioral modifications such as weight loss; surgery and joint replacement.

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.

"The exciting thing about this new approach is that it has been found to have no side effects, it is relatively low-cost in the long-run and the onset of pain relief is immediate," says Dr. Nelson. "We look at electromagnetic pulses as a potential way to improve quality of life and independence for those who suffer from osteoarthritis of the knee."

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.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
