The impact of transcranial direct current stimulation on neuromuscular control during directional change.

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
The ability to change direction is crucial in soccer; however, evidence regarding acute intervention methods remains limited. Transcranial direct current stimulation (tDCS), a noninvasive brain modulation technique, has already been shown to enhance muscle function and athletic performance. Still, its influence on athletes' change-of-direction skills-especially at different turning angles-has not been fully clarified. In this study, thirteen male collegiate soccer players were divided into two groups: an experimental group receiving real stimulation and a control group receiving sham stimulation. The experimental group underwent twenty minutes of bilateral anodal tDCS over the primary motor cortex at 2 mA. tDCS significantly improved 45° COD performance (p = 0.027), while no changes were observed at 90°. Electromyography results provided further detail: during 45° turns, the integrated EMG values of the vastus lateralis increased significantly (p = 0.021), and during 90° turns, the root mean square values of the vastus medialis also rose significantly (p = 0.047). Altogether, these findings suggest that tDCS can act as an effective acute intervention to improve athletes' agility in direction changes, offering a practical edge for performance enhancement. This study was prospectively registered in the Chinese Clinical Trial Registry (ChiCTR290251, October 15, 2025).
