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 Radio frequency involves giving short pulses of radio frequency 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 radio frequency works by a different mechanism than does regular radio frequency.

The great advantage to pulsed radio frequency 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 radio frequency lesioning (PRFL), as a nondestructive neuro modulation technique, is more attractive for chronic pain management
