A well-conducted placebo-controlled trial in Finland has demonstrated, that the controversial BEMER therapy is useless in Fibromyalgia, finnish media has just reported.[>>1] The trial results have just been published in the respected Bioelectromagnetics journal ahead of print.[>>2]
In the study, 108 patients with fibromyalgia diagnosis according to American College of Rheumatology’s (ACR) criteria were randomized to active (N=57) and sham treatment (N=51). They used the BEMER devices as advised in manufacturer instructions for 12 weeks. Then the groups crossed over, meaning that every participant had active and sham treatment at some time.
There was exactly no difference between sham and real BEMER treatment at the end of these periods. The study was adequately powered to find even small differences between sham and active application. Thus, it strongly refutes earlier results from the much smaller trials, which seemed to hint at an effect.
Furthermore, the authors comprehensively explain why there is no effect: The magnetic field is far too weak to affect human physiology or microcirculation. Therefore, it’s unlikely that this kind of “therapy” will have anything else than a placebo effect also in other uses.
Because it is an important study, and it was financed by public funds from finnish tax payers like me, I make the full text article available here. Objections be directed at email@example.com.
