Using Pulsed Radiofrequency for Chronic Pain

Radiofrequency thermocoagulation (RFTC) is a mini- mally invasive and target-selective modality procedure that has been used for over three decades. This has been demonstrated to be successful for reducing pain in the treatment of various chronic pain syndromes. Currently case reports and retrospective analysis of patient series suggest that pulsed radiofrequency (PRF) may be con- sidered for the management of shoulder pain, glosso- pharyngeal neuralgia, head and facial pain, groin pain, meralgia paresthesia, and various types of neuropathic pain (1).
