Movement-related cortical potentials underlying motor preparation and execution in children with attention-deficit/hyperactivity disorder.

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
objectiveMotor control difficulties are highly common in Attention-Deficit/Hyperactivity Disorder (ADHD), yet the etiology of this comorbidity remains unclear. We examined (1) whether children with ADHD have atypical movement-related cortical potentials (MRCPs) during movement preparation and/or execution compared to typically developing (TD) children, and (2) whether MRCPs associated with visual-motor performance and ADHD symptoms overlap.
methodsMRCPs and visual-motor integration (VMI) were measured among 66 right-handed children with ADHD and 30 TD children (ages 7-11 years). Caregivers reported on ADHD symptoms. MRCPs were extracted over fronto-central scalp regions during two ERP tasks requiring button presses.
resultsChildren with ADHD had lower accuracy on MRCP tasks and reduced VMI scores, compared to TDs. ADHD diagnosis was associated with attenuated correct trial MRCP amplitudes at a fronto-midline electrode during movement preparation, but not execution. ADHD symptom severity and reduced error trial MRCP amplitudes each explained unique variance in VMI performance.
conclusionsPediatric ADHD is associated with atypical cortical activity during movement preparation, but not execution. VMI performance and ADHD diagnosis were associated with distinct motor cortical processes, providing support for the separate etiology hypothesis. SIGNIFICANCE: Motor difficulties in children with ADHD may require an intervention approach that is distinct from the treatment of core ADHD symptoms.
