Feasibility study of transcranial direct current stimulation (tDCS) efficacy in patients with neurogenic dysphagia: Study Protocol.
Article in MethodsX, 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
Non-invasive brain stimulation (NIBS) techniques have shown increasing scientific relevance due to their potential positive effects across several health domains, including rehabilitation and clinical treatment. Among these techniques, transcranial direct current stimulation (tDCS) has emerged as a promising approach for the treatment of various neurological symptoms and conditions. Specifically, tDCS has shown potential benefits in speech therapy, hearing, voice modulation, and particularly in the treatment of neurogenic dysphagia. This feasibility study aims to assess the implementation of tDCS in patients with neurogenic dysphagia and to determine whether a future randomized controlled trial (RCT) is justified. The study will be conducted at the Neurorehabilitation and Neuromodulation Laboratory, located at the Interprofessional Health Clinic School (CEIS) of the Federal University of Espírito Santo, Brazil. Twelve patients will be recruited by convenience sampling and will undergo eight 30-minute tDCS sessions (twice a week over four weeks). Swallowing function will be assessed using the Dysphagia Risk Evaluation Protocol (PARD), the Eating Assessment Tool (EAT-10), and the Quality of Life in Swallowing Disorders Protocol (SWAL-QOL) before and after the intervention. This protocol offers preliminary insights into the clinical feasibility of tDCS for dysphagia and contributes to the development of future clinical trials in this field.
