The Effects of tDCS on Speech Fluency in People Who Stutter: A Narrative Review.
Review in The European journal of neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
To improve the outcomes of current treatments for stuttering, researchers have explored adjunct tools such as transcranial Direct Current Stimulation (tDCS). The purpose of this paper is to review the literature investigating the effectiveness of tDCS for people who stutter (PWS) and offer some directions for future research. To achieve the objective of this study, we conducted a narrative review of the existing literature. Articles were selected using these inclusion criteria: participants, tDCS protocol, control group and primary outcomes. Our literature search was limited to studies published in English with no limits on the publication year. We only extracted data from studies that investigated the effects of tDCS on PWS. Systematic reviews, meta-analyses and other forms of reviews regarding tDCS were not included. We identified 101 studies during the exploratory phase. Ultimately, seven studies met our inclusion criteria. Of the included papers, five studies reported mixed effects, one study showed no effect and one study showed positive effects of tDCS. We summarized the studies in terms of several methodological features and the observed effects from tDCS. We also used SimNIBS modelling to compare the effects of different stimulation parameters on brain activity and outcomes. The studies reviewed in this study have reported a variable effectiveness of tDCS for enhancing speech fluency in PWS. As a result, it remains unclear whether tDCS is an effective tool for stuttering intervention, and the optimal stimulation parameters are not yet established. Several suggestions for future research are offered.
