Comparing two methods of deep brain stimulation for Parkinson's disease

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

Not applicable Interventional Xuanwu Hospital, Beijing · NCT06742450

What this trial studies

This study aims to compare the effectiveness and patient satisfaction of constant current versus constant voltage deep brain stimulation in patients with Parkinson's disease. It is a randomized, parallel controlled, multi-center trial involving approximately 180 participants who will be followed for up to 12 months after surgery. Participants will be assigned to either current mode or voltage mode of stimulation and will undergo comprehensive assessments at baseline and during follow-up. The study will evaluate programming burden, power consumption, and overall satisfaction from both physicians and patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with idiopathic Parkinson's disease who have undergone bilateral subthalamic nucleus deep brain stimulation but have not yet powered on the device.

Not a fit: Patients with mental disorders, serious health conditions, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved deep brain stimulation techniques that enhance patient outcomes and satisfaction.

How similar studies have performed: Other studies have explored deep brain stimulation techniques, but this specific comparison of current versus voltage modes is relatively novel.
