ABSTRACTIntroduction: Low back pain is one of the most common and important health problems that affect the world's population. Intervertebral disc herniation is the main cause.
Objective: To evaluate the effect of treatment for pain due to lumbar disc herniation using pulsed electromagnetic fields.
Methods: A randomized, prospective and longitudinal study was conducted in 160 patients with a clinical and radiological diagnosis of uncomplicated lumbar disc herniation, which have more than six weeks of evolution. They attended the ozone therapy consultation at the Institute of Neurology and Neurosurgery from January to June 2015. The applications were made at Rampa polyclinic. The sample was divided into two groups of 80 patients each. Those in the control group were treated with analgesics, anti-inflammatory and muscle relaxants. Pulsed electromagnetic fields were applied to the others at the level of the lesion. The degree of improvement of all patients was assessed through the analog pain scale and functional capacity, using Oswestry questionnaire.
Results: The group treated with pulsed electromagnetic fields was statistically superior to the control group in all parameters. In the control group patients showed adverse reactions in their gastrointestinal system, but in the other group no unfavorable events were reported.
Conclusions: The use of pulsed electromagnetic fields for treating pain due to uncomplicated lumbar disc herniation, which have more than six weeks of evolution, was safe and effective.
