Model		Meta-analysis of studies evaluating PEMF exposures and effectiveness in treating arthritic knees
Details		Literature review (n = 9 sutdies) of pulsed electromagnetic field treatments compared with placebo was performed for osteoarthritis of the knee. The authors report no overall significant effect of PEMF treatments for pain (weighted mean difference 0.2; 95% CI-0.4 - 0.8) or stiffness (weighted mean difference 0.3; 95% CI -0.3 - 0.9), but there was a significant improvement in activity level (weighted mean difference 0.8; 95% CI 0.2-1.4). The authors conclude PEMF exposures may improve clinical outcome.
