I have read many published reviews of the medical literature on the effectiveness of pulsed electromagnetic fields (PEMFs) in the management of osteoarthritis of the knee. The conclusions reached by the authors, who are almost all academics and rarely personally experienced in the use of magnetic fields, are only modestly positive, indicating some benefit. The authors generally use very stringent criteria to judge the design of the studies to draw their conclusions. It is very challenging and expensive to design and carry out a study that would meet the strictest standards for high-quality research. These reviews yielded conflicting conclusions regarding pain and function benefits of PEMFs. The process of research is “painfully” slow, that is, many of us have to remain in pain and resort to ineffective and dangerous conventional approaches while we wait for the brick by brick science process to produce sufficient evidence that would be acceptable by even the most hardened skeptics.
