Stroke study: Deep Brain Stimulation
Official title Deep Brain Stimulation Motor Ventral Thalamus (VOP/VIM) for Restoration of Speech and Upper-limb Function in People With Subcortical Stroke
ClinicalTrials.gov ID: NCT06303869
What this study is testing
- What it's testing
- The study checks if deep brain stimulation can improve hand, arm, and speech abilities after a stroke.
- Who it's for
- It looks for people who have had a subcortical stroke and have difficulty moving their hand or speaking.
- What's involved
- Participants will have a surgical procedure to place electrodes in the brain, use external stimulators, and undergo tests to see how movements and speech change with stimulation. The electrodes are removed after less than 30 days.
- Time commitment
- The study lasts about a month, including surgery, stimulation sessions, and follow‑up visits to monitor changes.
