What is Dorsal Root Ganglion Stimulation and How Does It Work?
Dorsal root ganglion stimulation therapy, often abbreviated as “DRG stimulation,” is a targeted form of pain treatment designed to treat nerve related pain, commonly from prior surgery or a past injury. It works by using electrical impulses from electrodes placed near the large nerves just prior to the nerves entering the spinal cord, to help block the pain signals that travel on those nerves on their path to the brain. By interfering with these nerve impulses, patients experience diminished pain.
Dorsal root ganglion stimulation is a two-part process where a trial period is performed prior to any permanent surgical procedure being performed. This allows patients to try the therapy by undergoing a minimally invasive procedure without surgical incisions. If the trial period is successful, patients will be set up for the permanent implant. Both procedures are performed safely with local numbing medication and mild sedation.
