Official Title
A Multi-Center, Controlled Study to Evaluate Use of CereGate Therapy to Reduce Freezing of Gait in Participants Diagnosed With Parkinson's Disease
Purpose
A Multi-Center, Controlled Study to Evaluate Use of CereGate Therapy to Reduce Freezing of Gait in Participants Diagnosed with Parkinson's Disease.
Detailed Description
This is a multi-center, controlled, study in which participants diagnosed with Parkinson's Disease (PD) and previously implanted with a subthalamic nucleus deep brain stimulation (STN-DBS) System will be assessed prior to initiation of CereGate (CG) therapy, and during CereGate therapy. No randomization will occur in this study.
Participants will complete a total of five study visits (2 Screening Visits, Initiation Visit, day 60 follow-up and day 61 follow-up). The expected duration of participation in the clinical study is up to 104 days for each subject.
Up to 41 participants diagnosed with PD previously implanted with a compatible STN-DBS System will be enrolled at up to five (5) sites in the United States. A maximum of 15 subjects may be enrolled at any site.
