to the Coma/Near Coma Scale
Coma/Near Coma (CNC) scale was developed to measure small clinical
changes in patients with severe brain injuries who function at very
low levels characteristic of near-vegetative and vegetative states.
The CNC was designed to provide reliable, valid, easy, and quick
assessment of progress or lack of progress in low-level brain injured
patients. The CNC essentially expands the levels of the Disability
Rating Scale (DRS) that incorporate the vegetative and extreme
vegetative categories. The CNC has five levels, based on 11 items,
that can be scored to indicate severity of sensory, perceptual,
and primitive response deficits.
