This study explores if a personalized brain stimulation method called **repetitive transcranial magnetic stimulation (rTMS)** combined with walking exercises can help people with Parkinson's disease who have **freezing of gait (FOG)**. FOG is a symptom where people feel stuck and can't start walking. The study will involve up to 15 visits over about 16 weeks. Each visit includes brain imaging, using a safe, non-invasive rTMS device, and walking exercises. Participants are assessed on their walking, Parkinson's symptoms, and brain response. The study is conducted at the Medical University of South Carolina (MUSC) for adults aged 50-80 with Parkinson's and FOG.
- Time Commitment: Up to 15 visits over 16 weeks.
- Eligibility: Ages 50-80 with Parkinson's and FOG.
- Risks: No direct medical benefits, investigational use of rTMS.
Participation is voluntary, and you can leave the study anytime without affecting your medical care.
