Constant Current Versus Constant Voltage Subthalamic Nucleus Deep Brain Stimulation in Patients with Parkinson's Disease

Prospective Study of Constant Current Versus Constant Voltage Deep Brain Stimulation in Patients with Parkinson's Disease

To compare the efficacy, programming burden, power consumption, and physicians' and patients' satisfaction between current mode and voltage mode of deep brain stimulation in each period one year after surgery.

This is a randomized, parallel controlled, multi-center study to compare the efficacy, programming burden, power consumption, and physicians' and patients' satisfaction between current mode and voltage mode of deep brain stimulation in each period one year after surgery. Participants will be followed for up to 12 months. Approximately 180 PD participants will be recruited from up to 14 sites. Participants will be randomized to current mode or voltage mode after DBS surgery and be comprehensively assessed at baseline and follow up according to the protocol developed.
