The effect of physical activity on Parkinson's disease outcomes in patients with bilateral subthalamic nucleus deep brain stimulation: a systematic review.
Synthesis in Frontiers in neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Subthalamic nucleus deep brain stimulation (DBS-STN) is a recognized treatment for advanced Parkinson's disease. While it improves some clinical symptoms, especially bradykinesia and rigidity, it has limited application for late motor symptoms. Moreover stimulation-related motor adverse effects can increase the motor burden. There is a clear need to develop additional therapies that complement deep brain stimulation in controlling late motor symptoms. Physical activity is a commonly used and recommended form of therapy for patients with Parkinson's disease, supplementary to pharmacological therapy. However, there are no clear recommendations including patients after implantation of DBS-STN stimulators in the group undergoing physiotherapy. Objective: The objective of this study is to systematically review the literature on physiotherapy interventions for patients who have undergone DBS-STN implantation and their influence on motor outcomes. Methods: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines, and a total of 10 studies were included. Results: Despite heterogeneous physiotherapy protocols, the main outcomes (balance, postural stability, gait speed, functional mobility) improved consistently, while motor severity scores and cognitive or neurophysiological effects remain underexplored. Conclusion: Current evidence supports the use of physiotheruapy as a potentially effective and safe addition to the management of motor symptoms in patients after DBS-STN. Future trials with standardized physiotherapy protocols and uniform outcome measures are needed to create overall recommendations.
