Deep brain electrical stimulation, or DBS for short, is an effective therapy for the treatment of moderate to advanced Parkinson’s disease. This therapy was first used in China in 1998, and it has been 17 years since then. The therapy has significantly improved the motor impairment and greatly improved the quality of life of Parkinson’s patients. So, what exactly is DBS therapy? The following diagram makes it easy for you to understand the installation and connection of the DBS device. Figure A The stimulation electrodes are located in specific nuclei in the deep brain, and the pulse generator (with power supply unit) is fixed on the skull and connected by wires in between, this method reduces the risk of rupture and infection. Figure B: The stimulation electrode is located in a specific nucleus deep in the brain, the pulse generator is fixed under the clavicle, and the two are connected by an extension wire through a subcutaneous tunnel. Figure C shows that the physician connects the pulse generator via a programmable controller, thus allowing the stimulation parameters to be changed.
