DRG is the ganglion on the dorsal root of every spinal nerve. It is where the cell bodies of sensory neurons are located; hence, it is chiefly involved in the transmission of sensory (pain) information.
Pulsed Radiofrequency involves giving short pulses of radiofrequency waves twice a minute. This technique differs from standard radio frequency procedures in that the tissue is seldom brought up to temperatures above 42 degrees Celsius. Temperatures this low does not damage the cells, so that pulsed radiofrequency works by a different mechanism than does regular radiofrequency.
The great advantage to pulsed radiofrequency is that it’s safe, particularly for use around the dorsal root ganglion or for peripheral nerves, such as the suprascapular nerve. It is particularly useful in treating headaches from whiplash, in treating pain going down the leg from inoperable spinal stenosis, and for treating back, shoulder and groin pain.
DRG pulsed radiofrequency lesioning (PRFL), as a nondestructive neuromodulation technique, is more attractive for chronic pain management
