Table 1.

Clinical characteristics of the sample and behavioral results. Age is reported in years. Diagnosis refers to the two screening CRS-R before enrollment (minimally conscious state—MCS, emergence from minimally conscious state—eMCS. Etiology reported (traumatic brain injury—TBI). Time since injury (TSI) reported in months. Total CRS-R scores pre- and post-stimulation are reported for each condition, the modified index of the CRS-R is reported on the second row for each patient. N/A—Not assessed.
