NCT06321146

Brief Summary

Development of objective, reliable, and convenient assessment methods of disorders of consciousness is crucial. We aim to conduct multicenter prospective observational study and non-invasively collect EEG from patients with traumatic coma to analyze the sequential characteristics of EEG power spectrum, and explore their prognostic value for consciousness recovery.
