Temporal Dynamics of Beta Power Related to the Stun Effect in Parkinson's Disease Patients after Deep Brain Stimulation Surgery.
Article in Movement disorders : official journal of the Movement Disorder Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundDeep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for patients with advanced Parkinson's disease (PD). Early programming of DBS may be complicated by the postoperative "stun effect," which also may impact local field potentials (LFPs).
methodsPercept PC neurostimulators (Medtronic) were used to continuously record LFPs from the STN in 32 PD patients at home during the first 2 months after DBS surgery. Average beta peak power ("beta power") per day was analyzed using change-point analysis.
resultsMedian beta power across patients showed an upward trend with a changepoint 24 to 40 days after surgery. Median beta power directly following DBS activation did not significantly drop but continued to increase beyond the DBS activation visit.
conclusionThe neurophysiological stun effect persists for at least 3 weeks and should be taken into consideration when timing and applying sensing-informed or adaptive DBS based on beta power. © 2025 The Author(s).
