Before having a dorsal root ganglion stimulator placed, you will undergo a trial period. This is done to ensure that DRG stimulation is an effective treatment for your pain. A small wire will be placed along the affected DRG and connected to a generator. The generator will be worn outside of the body and can be used to adjust the strength and frequency of the electrical impulses. The trial period is about a week. If you experience a 50% or more reduction in pain, then the procedure is considered a success and the permanent device can be placed.

The placement of a DRG stimulator is a minimally invasive outpatient procedure performed with local anesthetic and mild sedation. During the procedure, a small device is placed under the skin through a small incision in the upper buttock or lower back. This means that there is no need for open surgery, which can be a big benefit for many people. The stimulator is then connected to wires that are threaded through the body to the epidural space where the DRG is located. If the stimulator is not providing enough relief, it can be adjusted or turned off.
