Deep brain stimulation (DBS) uses a medical device to stimulate the source of the symptoms of essential tremor on one side of the body. Clinical studies have shown that Medtronic DBS Therapy for essential tremor provides improved ability to do everyday activities, less tremor, and less disability (as reported by the patients).1


Medtronic DBS is FDA-approved to treat one “upper extremity,” which means one arm and hand. DBS may help symptoms of essential tremor that happen with or without trying to move.

When medications aren’t effective and your symptoms make everyday life a challenge, DBS may help. Symptom control may help you continue to do what’s important to you, like taking care of family or continuing to work. Or participate more fully in an event like a vacation or a family wedding.

DBS Therapy is not for everyone, so it's important to talk with your doctor about the benefits and risks.

How DBS Works

The DBS System

The DBS System

An implanted Medtronic deep brain stimulation system sends signals to an area in the brain that controls movement. 

DBS Therapy uses a small, pacemaker-like device, placed under the skin of the chest, to send electrical signals through a very thin wire (lead) to an area in the brain that controls movement. To give you relief, these signals block some of the brain messages that cause the movement symptoms of essential tremor.
