Magnetic fields play an important role in Western medicine. For instance, they are used for magnetic resonance imaging (MRI), pulsed electromagnetic fields, and experimental magnetic stimulatory techniques. Several studies have evaluated the use of magnetic field therapy applied to areas of osteoarthritis or degenerative joint disease. In particular, this research has focused on knee osteoarthritis. However, most studies have been small or poorly designed or reported. Efficacy remains clear. Notably, one promising small study published in 2004 by Wolsko et al. reported some benefits. Larger and better quality studies are needed before a recommendation can be made in this area. Initial evidence has failed to show improvements in knee pain with the use of magnet therapy. However, due to methodological weaknesses with this research, the conclusions cannot be considered definitive. Read more
