By means of coherence meters, extensive series of measurements are executed on the surface of the skin within seconds. The multitude of measured body conductivity is evaluated statistically. Conclusions can be drawn from their distribution curve on the degree of organisation in the living and highly dynamic organism.

Curves corresponding to logarithmic normal distribution are in a direct correlation with coherent conditions. Curves deviating from logarithmic distribution suggest incoherencies and thus disturbances in the system.
