Using GPi brain signals to guide DBS programming for primary dystonia
Official title: Optimising Deep Brain Stimulation for Dystonia Using Local Field Potentials
Run by Newcastle-upon-Tyne Hospitals NHS Trust · NCT07309133 · Data updated 2026-11-12
This study will test whether recording local field potentials from the globus pallidus interna with the Medtronic Percept device can help guide DBS programming and improve symptoms in adults with primary dystonia.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with a clinical diagnosis of primary (idiopathic or genetic) dystonia who are candidates for GPi DBS and able to give informed consent.
✕Probably not a fit
Patients with secondary or functional dystonia, significant cognitive or psychiatric disorders, or recent participation in other therapeutic trials are excluded and therefore unlikely to benefit from this protocol.

What this trial studies
This single-site, prospective observational study will enroll adults with primary dystonia who are candidates for GPi DBS and implant the Medtronic Percept device to record chronic local field potentials. The protocol includes an internal pilot and two main cohorts comparing traditional programming based on clinical assessment and imaging with programming guided by LFP peak characteristics. Investigators will examine whether alpha–theta LFP peaks correlate with dystonia severity, how LFP profiles change with stimulation, botulinum toxin, or medications, and whether LFP-guided settings produce similar or better clinical outcomes. Clinical severity measures and continuous LFP recordings from implanted GPi electrodes will be collected over follow-up for comparison.
Why it matters
Potential benefit: If successful, LFP-guided programming could shorten the time to optimal DBS settings and improve symptom control for people with dystonia.
How similar studies have gone: LFP-guided approaches have shown utility in Parkinson's disease and small short-term dystonia recordings suggest low-frequency peaks may be informative, but chronic GPi sensing to guide programming in dystonia is still novel and unproven.
