Study Summary

This trial is testing whether two electrode placements are better than one for treating Parkinson's Disease. An adaptive system will also be developed.

Who is the study for?

This trial is for individuals with severe Parkinson's Disease who are candidates for deep brain stimulation (DBS) surgery. Participants must be able to consent, attend follow-ups, have levodopa-related side effects, and show at least a 30% improvement with levodopa. Excluded are those with dementia, pregnancy, unsafe surgical risks, other severe neurological diseases or conditions requiring MRIs, untreated depression, electromagnetic implants or metallic implants.Check my eligibility

What is being tested?

The study tests the effectiveness of DBS electrodes implanted in two common brain areas (STN and GPi) versus just one area. It also aims to develop an adaptive DBS system that adjusts based on brain signal measurements from these electrodes.See study design

What are the potential side effects?

Potential side effects may include discomfort at the implant site, headache following surgery, infection risk from the procedure itself as well as possible speech or balance issues related to changes in brain stimulation.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.

Primary outcome measures

Change in Unified Parkinson's Disease Rating Scale (UPDRS) score: "on" medication, "on" stimulation at 12 months after IPG implant.

Change in Unified Parkinson's Disease Rating Scale (UPDRS) score: "on" medication, "on" stimulation at 24 months after IPG implant.

Change in Unified Parkinson's Disease Rating Scale (UPDRS) score: "on" medication, "on" stimulation at 48 months after IPG implant.

Experimental Treatment

Group I: Implanted RC+SExperimental Treatment4 Interventions

Implanted Medtronic RC+S IPG with dual DBS electrodes in STN and GPi. DBS stimulation will be administered to: 1) STN alone, 2) GPi alone, 3) cooperative STN + GPi, and 4) adaptive, closed-loop stimulation of STN and/or GPi.
