The same CPT® code is used for both types of percutaneous leads. There is a version used for the trial phase and a version used for permanent implantation. This may occur once the lead is in place and is connected to the neurostimulator and activated. A percutaneous lead is inserted via needle into the epidural space. Do not undergo a trial if you have an active infection the day of the procedure. Additional risks to the patients, as a result of the placement and stimulation of the lead in the area of the dorsal root ganglion (DRG), include pain from setting the stimulation parameters too high. The benefits of the screening trial may be immediate, or they may take a few days.Ĭomplications can occur during the trial, including bleeding into the epidural space, infection, and other side effects. The Proclaim DRG Neurostimulation System is the first and only neurostimulation device approved only for complex regional pain syndrome (CRPS) and those seeking relief from causalgia -nerve pain following surgery or injury.However, it has recently been proven that applying an electrical field to the dorsal epidural space might activate a larger number of neural structures. Spinal cord stimulators require two procedures to test and implant the device: the trial and the implantation. Neuromodulation, defined as the alteration of nerve activity through targeted stimulus delivery, was first introduced in 1967. Don’t let it come into direct contact with water when showering or bathing. In 1967, Shealy first inserted the dorsal column stimulator into patients suffering from cancer pain. The trial system isn’t waterproof, so you’ll need to keep it dry.Generally, you’re free to go to work, do your daily routine, and try some activities you’ve been avoiding because of pain. The spinal cord stimulator trial, which lasts about a week, involves stimulation through thin wires inserted into the body and controlled by an external transmitter.Your doctor will give you instructions to follow, including any limitations like twisting and heavy lifting, which may dislodge the trial leads.The benefits of the therapy may be immediate or take a few days. An advantage of this therapy is targeted stimulation to specific areas of the body. The Dorsal Root Ganglion is a small bundle of nerves located near the spinal cord. Consider doing some of the things you normally can’t do because of your pain - like walking upstairs, standing in one place, or getting ready in the morning. DRG is a version of spinal cord stimulation where the leads are placed to stimulate to dorsal root ganglion rather than the spinal cord itself.
