    AbstractThe Glasgow Coma Scale permits 120 possible mathematical combinations of eye, verbal and motor scores. Out of these only about 15 are clinically valid and useful in the assessment of altered consciousness. A mathematical analysis of this pruned scale shows a predominant skew towards the motor response. Without clinically altering the scale. The numerical values can be modified to produce a more equitable dominance by each of the factors and greater precision. This is also necessary as the value of a unit is the same in the sum score, whether contributed by the eye, verbal or motor elements.
