This study is checking if a new therapy, called CereGate, can help people with Parkinson's Disease (PD) who have trouble walking because of a symptom called "Freezing of Gait." People in this study must already have a special device implanted in their brains, called a subthalamic nucleus deep brain stimulation (STN-DBS) system.
No one will be randomly assigned to groups in this study, and everyone will try the therapy. There will be five visits to the study center, and the whole study lasts about 104 days.
The study will happen at eight places in the United States, with up to 41 people joining. Each place can have up to 15 people participating.

• This study lasts 104 days with five visits required.
• Participants must already have a STN-DBS system implanted.
• Eligibility includes specific age and health conditions.
