Analysis of the Factors Related to the Effectiveness of Transcranial Current Stimulation in Upper Limb Motor Function Recovery after Stroke: a Systematic Review.

Transcranial direct current stimulation is one of the non-invasive techniques whose main mechanism of action is based on its modulation of cortical excitability. The objective of this study is to analyze the variables (i.e, demographics, clinicals, stimulation parameters) that could influence into the responses during rehabilitation of the upper extremity in patients with stroke.
