Effect of Pulsed Magnetic Field on Bone Density in Juvenile Rheumatoid Arthritis

Abstract: Introduction: Juvenile rheumatoid arthritis (JRA) has long been suspected to affect bone mineralization because of poor linear and skeletal growth, an increased number of fractures, and osteopenia, observed by radiography, in children with the disease. Methods: 30 children, with polyarticular JRA, aged 8 to 12 years were included. Children were randomized for treatment in two groups. In the study group received pulsed magnetic field therapy 3 times per week for successive 3 months. In the control group received the conventional physical therapy program only. Evaluation of bone mineral density (BMD) using Dual Energy X-ray Absorptiometry (DEXA) was performed before and after the treatment. Results: BMD of femur post treatment for the control and study groups was 0.735±0.166 and 0.866±0.125 (g/cm²) respectively. BMD of the lumbar spine for the control and study groups were 0.657±0.121 and 0.75±0.102 (g/cm²) respectively. BMD of total body for the control and study groups were 0.723±0.097 and 0.807±0.11 (g/cm²) respectively. The differences between both groups in their post treatment mean values of BMD was statistically significant as (p<0.05). Conclusions: Pulsed electromagnetic field therapy is effective, innovative, non-invasive, non-expensive and can be used as a new trend physical therapy modality in the treatment of osteoporosis in JRA.
