Preventing slowing down of alpha rhythms in stroke patients through modulation of cortical excitatory-inhibitory balance: a randomized controlled trial.

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
Several procedures have been developed to enhance the rehabilitation of stroke patients. However, most techniques struggle to promote sustained recovery in the months following the treatment. Therefore, it is essential to understand the mechanisms that can be harnessed during treatment to potentiate retention of benefits and sustained recovery. While stroke patients often suffer from thalamocortical dysrhythmia (TCD), a perturbation in alpha (8-13 Hz) rhythms caused by decreased excitation in the cortico-thalamic projections, the functional relevance of TCD in stroke patients is not yet clear. We propose that TCD can be counteracted by combining focal stimulation of the motor cortex with virtual-reality (VR) based rehabilitation, which engages distributed networks associated with goal-oriented behavior. Critically, we investigate whether this can be the key to promoting sustained recovery in stroke patients. We compare thalamocortical rhythms and behavioral recovery in patients receiving Sham and bilateral tDCS stimulation of the motor cortex during therapy with the Rehabilitation Gaming System (RGS). Our results reveal that patients in the tDCS group show a sustained recovery in all clinical scales up to three months post-treatment, as opposed to the Sham group. Furthermore, we demonstrate that the slowing down of alpha rhythms can be counteracted by transcranial direct-current stimulation (tDCS), with a particular role for enhancing the excitability of parietal areas. That said, we found no correlation between changes in alpha rhythms and motor recovery. On one hand, our findings suggest that sustained recovery can be potentiated by tDCS-enhanced VR-based rehabilitation. On the other hand, enhancing the excitability of parietal areas while recruiting brain networks associated with goal-oriented behavior can successfully counteract TCD, even though this is likely not the main driver of sustained motor recovery.
