Clinical Trial Summary

Background: Disorder of consciousness(DOC) is a series of arousal and cognitive disorders secondary to the most severe brain injury. Once a patient is diagnosed with a DOC, a poor prognosis is assumed and the rehabilitation for whom is greatly limited. Therefore, the treatment of DOC poses extraordinary challenges. Various treatments protocols have been reported of successful in promoting rehabilitation of DOC patients. Repetitive transcranial magnetic stimulation(rTMS), as a non-invasive brain stimulation technique, has shown potentials for consciousness rehabilitation of DOC patients as it is effective in regulating the central nervous system. Methods and design: This protocol is a double-blind randomized sham-controlled crossover trial. Totally 30 participants will be randomly assigned to either group 1 or group 2 in a 1:1 ratio, with 15 patients in each group. Each patient will received 20 sessions, in which 10 sessions will be active and 10 will be sham, separated by 10-days washout period. The active-rTMS will include 10 Hz rTMS over the individual-targeted area on each participants. Primary and secondary evaluating indicators will be performed at each baseline and after rTMS treatment. Primary outcome will be determined as behavioral response to treatment as measured using the Coma Recovery Scale - Revised (CRS-R). Resting-state high-density EEG will be also recorded to investigate the neurophysiological correlates by rTMS. Discussion:This study will contribute to define the role of rTMS for the treatment of DOC patients and characterise the neural correlates of its action. The investigators proposed a method of individualized target selection for DOC patients based on the existing gold standard CRS-R score and MRI, and used a cross randomized controlled trial to verify the role of rTMS in DOC treatment.
