Using the DOCS, the researchers evaluated military veterans and civilians over age 18 years who were unconscious after a severe brain injury. The test stimuli were organized into eight subscales, including social knowledge; taste and swallowing; olfactory; proprioceptive (perception of one's body in space) and vestibular (balance); auditory; visual; tactile; and testing-readiness. The investigators found that DOCS accurately detected improvements, declines and plateaus in neurobehavioral functioning in unconscious patients.
The study also showed how repeated measures using DOCS improved medical and rehabilitation management during coma recovery. The investigators found previously undetected secondary medical complications, which were successfully treated.
