 RA is a condition characterized by pain, fatigue, sleep disturbances, and mood changes. These symptoms often persist despite the use of nonsteroidal anti-inflammatory drugs NSAIDs and disease modifying antirheumatic drugs DMARDs. Many women for whom these drugs do not work turn to complementary and alternative therapies, including the use of magnetic devices. Although few studies have investigated the effects of low strength PMF pads in persons with RA, evidence suggests that PMF may help relieve pain, inflammation, and fatigue. This study will determine the effects of a PMF device on RA symptoms in postmenopausal women.
