Phase
PHASE4
Status
RECRUITING
Sponsor

Plain-Language Summary

The goal is to identify brain imaging markers that predict whether subthalamic nucleus deep brain stimulation will help with freezing of gait in people with Parkinson's. The team uses fMRI to map brain activity linked to freezing and to the response to DBS, while the DBS itself delivers continuous electrical pulses to the subthalamic nucleus to modulate abnormal motor circuits, often improving tremor and motor fluctuations and sometimes allowing lower levodopa doses, though effects on freezing can vary. The study is for adults over 40 with Parkinson's by UK Brain Bank criteria who have documented freezing of gait and have been clinically selected for STN-DBS at MUSC; people with non-PD gait problems, inability to complete OFF-state gait tests, MRI contraindications, or non-3T MRI compatible DBS devices are excluded.
