This procedure uses cooled radiofrequency energy through a probe to safely target the sensory nerves responsible for sending pain signals. A radiofrequency generator transmits a small current of RF energy through an insulated electrode, or probe, placed within tissue. Ionic heating, produced by the friction of charged molecules, thermally deactivates the nerves responsible for sending pain signals to the brain. RF energy heats and cools the tissue at the site of pain.
Radiofrequency can help treat pain located in the neck, low back, knee, hip, and shoulder.
