Automating Subthalamic Deep Brain Stimulation Programming with Evoked Resonant Neural Activity in Parkinson's Disease.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOptimal outcomes from subthalamic nucleus deep brain stimulation (STN-DBS) for Parkinson's disease (PD) depend on accurate stimulation of an ideal functional target within the dorsolateral STN. Clinical programming is heuristic, and objective methods are needed to improve efficiency and consistency.
objectivesThis study aimed to investigate the feasibility and acute motor benefit of STN-DBS programming, guided by intraoperatively recorded evoked resonant neural activity (ERNA) in patients with PD.
methodsWe assessed 12 patients with anatomically well-placed leads, 4-6 months following STN-DBS. The worst hemibody was tested off-medication. Acute motor benefit was double-blind assessed for three programming configurations: (i) chronic expert clinician settings, (ii) imaging guided, and (iii) an ERNA automated algorithm. We also compared therapeutic and side effect thresholds and the spatial distribution of fractionated current.
resultsERNA programming improved hemibody Movement Disorder Society-Unified Parkinson's Disease Rating Scale-Part III scores by 75.7% (median) compared with off-stimulation. This was not different from imaging (81.6%, P = 0.19) or clinician programming (68.8%, P = 0.33). Therapeutic thresholds (P = 0.90) and side effect thresholds (P = 0.57) did not differ across conditions. ERNA programming was 0.8-1 mm ventral and 0.3 mm posterior to imaging and clinician programming.
conclusionsA programming algorithm based solely on ERNA achieved acute motor efficacy and tolerability equivalent to expert clinical and imaging-based approaches. ERNA recordings took <1 min, under awake and general anesthetic conditions. These findings suggest that intraoperative ERNA can provide a rapid, objective, and practical starting point for STN-DBS programming. © 2026 The Author(s).
