Aspectos teóricos sobre la biofísica de la radiofrecuencia aplicada al tratamiento del dolor

Abstract

Interventional techniques for pain treatment have importantly increased in recent years, and particularly those based on radiofrequency energy, both thermal and pulsed. This report clarifies some important concepts about electrical phenomena involved during using these techniques, given a comprehensive explanation about types and modes of applying RF energy. Moreover, guidelines about the patterns of affected zones are defined dependent on the chosen arrangement. From a physical point of view, equations governing RF process are also presented. RF generator users should be knowledgeable about what is happening in each RF-based treatment in order to select the most suitable arrangement for the patient.
