Therapeutic Effects

by Robert B. Goldberg, Ph.D., Editor

Summary

Several articles concerned with therapeutic uses of EMFs are discussed briefly because they may be of relevance to potential mechanisms of action. The use of pulsed electromagnetic fields (PEMFs) to facilitate healing of bone nonunions was the first therapeutic application of EMFs in standard clinical medicine, with demonstrated efficacy in a number of clinical trials. We discussed first a study which applied PEMF stimulation to the osteoporotic knees of male patients with chronic spinal cord injuries to determine if the technique could neutralize bone loss or even increase bone mineral density. Another bone study reviewed in this article evaluated the effects of PEMF stimulation on bone healing in a tibial osteotomy model. In another area of potential therapeutic application of EMFs, a research group reviewed studies of the efficacy of using electrical and electromagnetic energy as adjuvant therapy for pressure ulcers such as bed sores. We presented a discussion of the role of reactive oxygen species in the presence of an external static magnetic field as it relates to treating cancer by photodynamic therapy. One author studied the effect of interferential currents on the release of cytokines by differentiated HL-60 cells in order to identify the mechanism for the pain-relieving effect.
