Cognitive motor dissociation (CMD) is a distinct clinical phenomenon in patients with disorders of consciousness after brain injury. It refers to the condition in which patients show no definite behavioral response to commands in bedside behavioral assessments, but command-related covert consciousness can be detected through neurofunctional testing, manifested as dissociation between task-related brain response and motor control. Compared with unresponsive patients without CMD, patients with CMD usually have a relatively favorable clinical prognosis, so early identification and assessment are of great significance. This article reviews the concept, mechanism and major advances in assessment techniques of CMD, so as to provide a reference for the early identification of covert consciousness in patients with disorders of consciousness.
