Electromagnetic Fields in the Treatment of Chronic Lower Back Pain in Patients With Degenerative Disc Disease

Abstract

AIM: To examine the effects of low-amplitude, low frequency electromagnetic field therapy (EMF) therapy in patients with persistent chronic lower back pain associated with degenerative disc disease. DESIGN: Double-blind, randomized and placebo controlled. INTERVENTION: EMF using a medical device resonator; control group underwent same procedures, except the device was turned off. OUTCOME MEASURES: Pain reduction and mobility. RESULTS: Improvements in overall physical health, social functioning and reduction in bodily pain were observed in the EMF group. The pain relief rating scale showed a higher level of pain relief at the target area in the EMF group. An increase in left lateral mobility was seen only in the EMF group. CONCLUSION: EMF treatment may be of benefit to patients with chronic nonresponsive lower back pain associated with degenerative disc disease.
