Follow up E.V.A. Examination

Below is a clear, complete, and neutral explanation of how the Voll method (EAV – Electroacupuncture according to Voll) is claimed to work and how an operator uses the device, without endorsing its medical effectiveness.

What the Voll (EAV) device

A Voll device is used in Electroacupuncture according to Voll (EAV), an alternative diagnostic method developed in the 1950s by Dr. Reinhold Voll, a German physician.

The device is essentially a low-voltage electrical resistance meter. It measures electrical skin conductance at specific points on the body that are believed (in EAV theory) to correspond to acupuncture meridians and internal organs.

Main components of a Voll device

1. Hand electrode (reference electrode)

   • Held by the patient, usually a metal cylinder

   • Completes the electrical circuit

2. Probe electrode (measuring stylus)

   • Held by the operator

   • Applied to acupuncture points on the hands or feet

3. Measurement unit

   • Displays readings (often 0–100 scale or digital values)

   • May include analog needles or digital screens

4. Optional test substance tray (on some models)

   • Holds vials, substances, or filters claimed to influence readings

How the Voll method works

1. Electrical measurement principle

• The device sends a very small electrical current (typically microamps) through the skin.

• It measures electrical resistance or conductance at the point touched by the probe.

• Skin moisture, pressure, temperature, and contact quality all affect readings.

2. Acupuncture point theory (EAV concept)

According to Voll theory:

• Specific acupuncture points are linked to:

  • Organs (liver, kidneys, lungs, etc.)

  • Body systems (nervous, endocrine, immune)

• Changes in electrical resistance at these points are believed to reflect imbalance or dysfunction.

3. Interpretation of readings (EAV theory)

Typical interpretation used by operators:

How a Voll operator uses the device (step-by-step)

Step 1: Patient preparation

• Patient removes metal jewelry

• Hands and feet are cleaned and dried

• Patient holds the reference electrode

Step 2: Point measurement

• Operator presses the probe onto specific acupuncture points

• Pressure must be consistent (this is critical)

• Readings appear on the display

Step 3: Observation of values

• Operator watches:

  • Peak value

  • Stability of reading

  • Whether the value “drops” after reaching a peak

Step 4: Comparative testing (optional)

Some operators:

• Place substances (homeopathic remedies, supplements, allergens) into the device circuit

• Re-measure the same point

• Observe whether readings change

This is claimed to indicate “compatibility” or “resonance,” though this has no scientific validation.

Step 5: Assessment and recommendations

Based on readings, the operator may:

• Identify “imbalanced meridians”

• Recommend supplements, homeopathy, acupuncture, or lifestyle changes

What the device actually measures (scientifically)

From a scientific standpoint, the device measures:

• Skin electrical resistance

• Influenced by:

  • Sweat gland activity

  • Skin hydration

  • Pressure of the probe

  • Temperature

  • Operator technique

It does not directly measure:

• Organ function

• Disease

• Infection

• Toxins

• Allergies

Summary

In short:

• The Voll device measures electrical skin resistance at acupuncture points

• The operator interprets these readings using acupuncture and meridian theory

• The method is considered an alternative and non-diagnostic by mainstream medicine
