Summary

This trial is testing a new procedure to treat focal hand dystonia, a condition that causes involuntary muscle movements. A device is placed in the chest and attached to wires in the brain, which stimulating the areas affected by dystonia can help to block nerve signals and improve symptoms.

Who is the study for?
Adults over 18 with severe focal hand dystonia (FHD) who haven't improved after two botulinum toxin treatments. They must not have widespread neurological issues, prior brain surgery, or be pregnant/nursing. Participants need to agree to use contraception and should not have metal in their body that's unsafe for MRI scans.
What is being tested?
The trial is testing deep brain stimulation (DBS) surgery for FHD treatment. A neurostimulator device will be implanted in the chest and connected to electrodes in the brain, aiming to block signals causing abnormal movements. The study spans five years with regular follow-ups.
What are the potential side effects?
Potential side effects include discomfort from the implant, infection risk at surgical sites, possible changes in mood or thinking patterns due to brain stimulation, headache or pain related to surgery recovery, and equipment malfunction requiring additional surgeries.
