Coma/Near Coma Scale
The Coma/Near Coma (CNC) Scale was designed to measure changes in neurobehavioral status among patients who have sustained severe brain injuries and whose clinical functioning is consistent with vegetative or near-vegetative states. The CNC Scale is useful when reliable, valid, and efficient assessment of patient’s functioning is required to substantiate clinical change or lack thereof in patients whose functioning is at markedly low levels. The CNC Scale expands the levels of the Disability Rating Scale (DRS). It has five levels and is comprised of 11 items that assess dysfunction in the sensory and perceptual dimensions and describes presence of primitive reflexes.
Recognizing a need for rehabilitation professionals to systematically identify and chart changes in functioning in patients whose clinical status is best characterized as approximately “vegetative,” the CNC was developed as a supplement to the Dementia Rating Scale (DRS)....
