Vascular Autonomic Sign

One thing that was noticed was the distinct change in the dimension or amplitude of the pulse on stimulation of certain points on the auricle. This occurrence was consistent and was both repeated and measured with the help of modern equipments.

This was named as the Vascular Autonomic Sign or VAS by Nogier. For successful implementation of Auriculotherapy and Auriculomedicine, it is very important to employ VAS for diagnosis and treatment accurately.
