An instrument in neurologic rehabilitation for the assessment of a person's 
clarity of consciousness must fulfill the need to provide the rehabilitation 
team with some information regarding the structuring of the rehabilitation 
process. The Vienna Vigilance Score is oriented toward cooperation within the 
rehabilitation team with the specific advantage of focus on the subject status 
of the patient on the basis of the dialogue. It does not use painful stimuli and 
is oriented toward the next developmental step of the rehabilitation process. 
The first extensive application of the Vienna Vigilance Score was carried out in 
a 3-year study of 38 children and adolescents. We report the comparison with 
other coma scales (Glasgow Coma Scale, Children's Coma Score, and Modified 
Glasgow Coma Scale) on 24 children and adolescents (1.4-16.8 years of age). The 
results showed satisfying statistical parameters: measuring range comparable 
with other scales; a Kendall tau correlation of .59 on both the Modified Glasgow 
Coma Scale and the Children's Coma Scale and of .66 on the Glasgow Coma Scale; a 
Spearman's rank order correlation of .70 to both the Modified Glasgow Coma Scale 
and the Children's Coma Scale and of .78 on the Glasgow Coma Scale. By accepting 
the Glasgow Coma Scale as a gold standard for classification of the level of 
coma, we can confirm satisfactory measuring qualities for the Vienna Vigilance 
Score.
