Effects of tDCS on brain function in patients with post-stroke cognitive impairment: a randomised controlled study protocol based on TMS and fNIRS.
Trial report in Trials, 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
backgroundTranscranial direct current stimulation (tDCS) positively affects post-stroke cognitive impairment (PSCI). However, the optimal stimulation protocol remains unclear, possibly because of the lack of objective assessment methods. Therefore, this study aims to investigate the impact of tDCS on the modulation of the excitation/inhibition (E/I) balance and its effects on brain function in patients with PSCI using transcranial magnetic stimulation (TMS) and functional near-infrared spectroscopy (fNIRS).
methodsThis study is a single-centre, two-armed randomised controlled trial. A total of 40 patients with PSCI will be recruited and randomly assigned to real and sham tDCS groups in a 1:1 ratio. Both groups will receive either real or sham tDCS in addition to conventional treatment. In both groups, electrodes will be placed at the same positions, with the anode and cathode above the left and right dorsolateral prefrontal cortex, respectively. The real tDCS group will receive continuous current throughout the session, whereas the sham tDCS group will receive current generation for only the first 30 s. The treatment will consist of a 3-week intervention with one session per day, five sessions per week and 30 min per session. A 4-week follow-up will be conducted at the end of the treatment. The primary outcome is the change in Montreal cognitive assessment (MoCA) scores from baseline (T0) to immediately post-intervention (T1). Secondary outcomes include Barthel index, levels of intracortical inhibition measured by TMS and cortical activation and interhemispheric connectivity assessed by fNIRS during a Stroop task. DISCUSSION: This study will combine TMS and fNIRS to explore the effects of tDCS on the modulation of the E/I balance and its impact on blood oxygen levels and neural activity. Our results are expected to provide a clinical reference for the development of more precise tDCS protocols.
