It is employed for both neuromodulation and neuroablative type procedures in interventional pain management. Technological advances have widened the scope of their use within clinical practice. The evidence base for both conventional and new technologies is accumulating. A clear understanding of the principles and technologies will enable the clinician to use it safely and effectively.
