Overview
Brief Summary
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.
Detailed Description
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.

Outcomes
Primary Outcomes
the JFK Coma Recovery Scale-Revised (CRS-R) scale
Time Frame: at baseline (T0), immediately after the end of the treatment (T1), 1 week later (T2).Investigators observed the changes from baseline to the end of stimulation.
The CRS-R is a tool used to characterise the level of consciousness.The CRS-R is a tool used to characterize the level of consciousness and to monitor neurobehavioural recovery in DOC. The scale consists of 23 hierarchically arranged items that comprise six subscales addressing the auditory, visual, motor, oromotor/verbal, communication and arousal processes. The lowest item on each subscale represents reflexive activity whereas the highest item represents cognitively mediated behaviors.
Secondary Outcomes
- EEG data ( electrophysiological parameters)(at baseline (T0), immediately after the end of the treatment (T1), 1 week later (T2).)
