Study type | Interventional |
Altered gamma activity has been observed in several neurological and psychiatric disorders, including a reduction in gamma synchronization in patients with disorders of consciousness. Modulation of gamma oscillations with rhythmic stimulation has been used as a possible therapeutic tool. Hence, we try to use acoustic and electric stimulation at gamma frequency to restore brain oscillation and thereby to improve conscious awareness in patients with disorders of consciousness.

Primary | Coma Recovery Scale-Revised scores | Coma Recovery Scale-Revised(CRS-R) scores are the gold standard for consciousness. CRS-R consists of 23 items, grouped into 6 sub-scales: auditory, visual, motor, oromotor, communication and arousal. The lowest score on each sub-scale represents reflexive activity; the highest represents behaviors mediated by cognitive input. The total score ranges between 0 (worst) and 23 (best). | Day 1-5, Day 11-15 | |
Primary | Neuropsychological assessment | EEG indicators could be used to assess the conscious level, including gamma oscillations and event-related potentials(P300). | Day 5 and Day 11 | |
Primary | Glasgow Outcome Scale-Extended | A widely used index for outcomes after brain injury | 1 year after stimulation |
