Study Overview
Brief Summary
Disorders of consciousness(DOC) is the most serious complications and has been widely paid attention to by the government. DOC patients cause large social and economic burden to our society for there has no effective cure so far. Spinal cord stimulation(SCS) for wake-promoting therapy has aroused scholars' attention and become a hot area recently. There was much debate about the effectiveness of SCS therapy, but because of the limitation of our understanding of consciousness and the uncertainty of parameters of the stimulation, So, to figure out the indications and effectiveness of neuromodulation therapy should be the first step, and finding individual treatment and parameter may have important implications for DOC patients.
Detailed Description
The spinal cord stimulation therapy is explorative at best at the moment. Attempts to improve the level of consciousness of patients in the different stages of DOC have shown some promise. Spinal cord stimulation(SCS) seem promising in some studies, suggesting that further research is needed. Current publications of DOC spinal cord stimulation therapy was not convincing because of the small number of patients and no randomized controlled trial. Therefore, there was much debate about the effectiveness of spinal cord stimulation therapy because of the limitation of our understanding of consciousness and the uncertainty of parameters of neuromodulation. The better understanding of brain function and large randomized trials are necessary. Future research should also focus on identifying specific neuro-biomarkers (i.e. neural network). So, to figure out the indications and effectiveness of neuromodulation therapy should be the first step, and finding individual treatment and parameter may have important implications for DOC patients.
Scientific Issues Targeted:1) To figure out the effectiveness of spinal cord stimulation therapy using random controlled trial. 2) To explore individual parameters of SCS techniques.

Arms & Interventions
Spinal cord stimulation and conventional treatment
Intervention: spinal cord stimulation (Procedure)
Conventional treatment
Outcomes
Primary Outcomes
the JFK Coma Recovery Scale-Revised (CRS-R) scale
Time Frame: 6 months after the end of the treatment(T3)
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 recording in resting state with Phase Coherence analysis(PC index)(6 months after the end of the treatment (T3))
