Pulsed radiofrequency denervation (PRF)

PRF is a procedure used to bring a long term pain relief to those demonstrated good but short lived response to a local anaesthetic injection. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals conducted by a sensory nerve. This procedure has a lower incidence of side effects in comparison to the conventional radiofrequency lesioning.
