Radiofrequency lesioning (or ablation) is a procedure used to reduce pain. An oscillating electrical current at a very high frequency is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.
A more recent development of radiofrequency lesioning is called pulsed radiofrequency. In this, the current is controlled so that the heating effect is less (to 42 degrees centigrade as opposed to 80 degrees) and this avoids damage to the nerve while affecting the way that the nerve carries pain impulses.
