Researchers at the University of Washington say they developed an advanced deep brain stimulation system designed to treat essential tremor without constantly being “on,” allowing for longer battery life and better treatment.
The system utilizes electrodes on top of the brain to sense movement in parts of the body that experience essential tremor, alongside a deep brain electrode to deliver stimulation only when it’s needed. Previous versions of deep brain stimulation systems delivered treatment at all times, with no way to turn the system off, even while the patient is asleep.
