Abstract

There has been a renewed research interest in transcranial direct current stimulation (tDCS) as an adjunctive tool for poststroke motor recovery as it has a neuro-modulatory effect on the human cortex. However, there are barriers towards its successful application in motor recovery as several scientific issues remain unresolved, including device-related issues (ie, dose-response relationship, safety and tolerability concerns, interhemispheric imbalance model, and choice of montage) and clinical trial-related issues (ie, patient selection, timing of study, and choice of outcomes). This narrative review examines and discusses the existing challenges in using tDCS as a brain modulation tool in facilitating recovery after stroke. Potential solutions pertinent to using tDCS with the goal of harnessing the brains plasticity are proposed.

摘要

经颅直流电刺激(tDCS)作为一种辅助工具用于中风后运动恢复,因其对人类皮层具有神经调节作用,重新引发了研究兴趣。然而,它在运动恢复方面成功应用存在障碍,因为一些科学问题仍未解决,包括与设备相关的问题(即剂量反应关系、安全性和耐受性问题、半球间失衡模型以及电极放置方式的选择)和与临床试验相关的问题(即患者选择、研究时机和结果选择)。本叙述性综述探讨并讨论了在使用tDCS作为促进中风后恢复的脑调节工具时存在的现有挑战。提出了与使用tDCS以利用大脑可塑性为目标相关的潜在解决方案。
