Transcranial Direct Current Stimulation in Patients With Disorders of Consciousness

To date, several studies have focused on the use of transcranial direct current stimulation(tDCS) in patients with impaired consciousness.However,its therapeutic effects have been variously documented.So,in this study ,investigators explore the effects of tDCS.

Background:tDCS was supposed as an experimental approach to disorders of consciousness treatment. Its therapeutic effects have been variously documented. Objective: The study aimed to investigate the reactivity of electroencephalography (EEG) and the clinical response of patients with disorders of consciousness and explore the neuromodulatory effects of highfrequency tDCS in DOC. Method:In this double-blind, randomized controlled trial,real or sham tDCS were applied to the left dorsolateral prefrontal (DLPF) cortex of participants with disorders of consciousness for two weeeks. Evaluations were blindly performed at baseline, immediately after the end of the 14-days treatment and 1 week later with the JFK Coma Recovery Scale-Revised (CRS-R) scale and EEG.
