Improve vision guided reaching ability

Trial ID
NCT05400499
Official Title
Deep Brain Stimulation for Visuomotor Function in Parkinsons Disease
Goal
Improve vision guided reaching ability
Status
RECRUITING
Sponsor
VA Office of Research and Development
Study Type
OBSERVATIONAL
Enrollment
40 participants
Conditions
Parkinson's Disease

Plain-Language Summary

The project aims to learn how stimulation of the subthalamic nucleus affects visuomotor skills, meaning how well people with Parkinson's use sight to guide reaching, balance, and hand-eye coordination. Researchers will observe people who already have bilateral STN deep brain stimulation, using pre-op MRI and post-op MRI or CT to map electrode location while testing vision-guided movement; STN DBS alters abnormal firing in motor circuits and is usually used alongside levodopa, and this study keeps medications and DBS settings stable to see specific effects on visuomotor tasks. About 40 adults of any sex are being enrolled, they must have bilateral STN DBS, available pre-op MRI and ability to get post-op imaging, and be Hoehn and Yahr stage 2 to 4 off medication with stable meds and DBS settings. People with dementia, untreated major depression or anxiety, prior Parkinson's brain surgery other than DBS, or signs of atypical parkinsonism are not eligible.
