Using patient-reported ratings to guide DBS programming
Pairing Subjective Patient Rating and Local Field Potentials for DBS Programming
Ludwig-Maximilians - University of Munich · NCT07336199
This project tests whether combining patients' own ratings with brain signal recordings can help find better DBS settings for people with Parkinson's who already have STN-DBS implants.

What this trial studies
This multicenter prospective and retrospective diagnostic study pairs patients' subjective visual analogue scale (VAS) ratings of stimulation effectiveness with objective local field potential (LFP) recordings, focusing on beta-band activity from implanted STN-DBS electrodes. Structural and functional neuroimaging are integrated to map individualized stimulation "sweet spots" and relate them to electrophysiological signals. The prospective cohort enrolls patients with sensing-enabled implanted pulse generators while retrospective data include recordings from compatible systems. The study is observational and aims to identify markers that could streamline and personalize DBS programming without changing clinical treatment.
Who should consider this trial
Good fit: Ideal candidates are adults aged 35–80 with clinically confirmed idiopathic Parkinson's disease who have bilateral STN-DBS implants and can communicate reliably, preferably with a sensing-enabled IPG for the prospective cohort.
Not a fit: Patients without compatible sensing-capable DBS systems, those with manifest dementia, severe comorbid medical or psychiatric conditions, or non-idiopathic Parkinsonism are unlikely to benefit from the findings.
Why it matters
Potential benefit: If successful, this approach could speed up DBS programming and personalize stimulation settings to improve symptom control while reducing clinic time and trial-and-error adjustments.
How similar studies have performed: Previous work has shown correlations between STN beta-band LFPs and motor symptoms and has supported sensing-enabled adaptive DBS, but combining patient VAS ratings with imaging-guided 'sweet spot' mapping for programming remains relatively novel.
