What is the VAS?
The VAS (Vascular Autonomic Signal), also known as the Nogier Pulse, is a subtle, measurable change in the radial pulse that occurs in response to specific sensory or energetic stimuli. First described by Dr. Paul Nogier in the 1970s, the VAS is a key diagnostic tool in auricular medicine and frequency therapy.

🔬 How Does It Work?
When the body is exposed to a stimulus—such as a frequency, color, ampoule, or acupuncture point—the autonomic nervous system reacts. This reaction produces a brief, subtle expansion of the arterial wall that can be felt by a trained practitioner on the radial artery, usually with the thumb.

This pulse reaction indicates that the body is “responding” to the information provided, and it allows the therapist to:

Detect active or blocked zones

Choose correct frequencies or remedies

Test for resonance or mismatch

Guide treatment with extreme precision

🧠 Why is VAS So Powerful?
Unlike subjective patient feedback, the VAS is an objective diagnostic signal generated by the body’s own autonomic system. It allows for non-verbal, real-time feedback about the energetic and functional state of the patient.

In experienced hands, the VAS becomes a powerful compass for:

Identifying interference fields or “disturbance zones”

Choosing correct laser frequencies

Locating active ear points or acupuncture points

Navigating complex cases with confidence
