A small study has shown that a pulsed electromagnetic field may be useful in the treatment of pain in fibromyalgia patients.
Researchers from the University of Western Ontario in Canada carried out the research and published their results in the winter issue of the journal Pain Research & Management.
The study found that exposure to a specific kind of electromagnetic field reduced pain in individuals with fibromyalgia but had no effect on pain in people who did not suffer from fibromyalgia.
The electromagnetic radiation used is known as a pulsed electromagnetic field (PEMF). Previous experiments with PEMFs have shown that they produce an analgesic (pain relieving) effects in many organisms.
The University of Western Ontario researchers conducted a randomized, double-blind, sham-controlled clinical trial involving 17 patients with chronic generalized pain from Fibromyalgia (FM) and 15 patients with chronic localized musculoskeletal or inflammatory pain.
